3.2 LCD Display

The LCD of the METER features two numerical registers

and various indications displayed to the user only when the

applicable function so requires.

Key:

1. Partial register (5 figures with moving comma FROM 0.1 to
99999) indicating the volume dispensed since the reset
button was last pressed.

2. Indication of battery charge.

3. Indication of calibration mode.

4. Totals register (6 figures with moving comma FROM 0.1 to
999999), that can indicate two types of Total:
4.1. General Total that cannot be reset (TOTAL).
4.2. Resettable total (Reset TOTAL).

5. Indication of total multiplication factor (x10 / x100 ).

6. Indication of type of total, (TOTAL / Reset TOTAL).

7. Indication of unit of measurement of Totals: L=Litres

Gal=Gallons

8. Indication of Flow Rate mode.

9. Indication of unit of measurement of Partial: Qts=Quarts

Pts=Pints

User Buttons
The TP101 features two buttons (reset and cal) which

individually perform two main functions and, together, other

secondary functions.
The main functions performed are:

Reset key - resetting the partial register and resettable

total (reset total).

Cal key - entering instrument calibration mode.

Used together, the two keys permit entering configuration

mode, useful for changing the units of measurements and

calibration factor.

4. operation

4.1
Daily Use
The only operations that need to be done for daily use are

partial and/or resettable total register resetting.
The user should use only the dispensing system of TP101.
Occasionally the meter may need to be configured or

calibrated. To do so, please refer to the relevant sections.

Below are the two typical normal operation displays.
One display page shows the partial and reset total registers.
The other shows the partial and general total. Switchover

from resettable total to general total display is automatic and

tied to phases and times that are factory set and cannot be

changed.

NOTE: 6 digits are available for Totals, plus two icons x

10 / x100. The increment sequence is the following:
0.0 99999.9 999999 100000 x 10 999999 x 10
100000 x 100 999999 x 100

4.2
Dispensing in Normal Mode
Normal mode is the standard dispensing.

While the count is made, the partial and

resettable total are displayed at the same

time (reset total).
Should one of the keys be accidentally

pressed during dispensing, this will have

no effect.

A few seconds after dispensing has

ended, on the lower register, the display

switches from resettable total to general

total: the word reset above the word total

disappears, and the reset total is

replaced by the general total.

This puts the meter in standby mode and remains stable until

the user operates the TP101 again.
4.2.1 Partial Reset
The partial register can be reset by

pressing the reset key when the meter

is in standby, meaning when the

display screen shows the word

TOTAL.

After pressing the reset key, during

reset, the display screen first of all
shows all the lit-up digits and then all
the digits that are not lit up.

At the end of the process, a display

page is shown with the reset partial
and the reset total.

After a few moments, the reset total

is replaced by the non resettable Total.

4.2.2 Resetting the Reset Total

The reset total resetting operation can

only be performed after resetting the

partial register. The reset total can in

fact be reset by pressing the reset key

at length while the display screen

shows reset total as on the following

display page:

Schematically, the steps to be taken

are:

1. Wait for the display to show normal
standby display page (with total only
displayed).

2. Press the reset key quickly.

3. The meter starts to reset the partial.

4. While the display page showing the
reset total is displayed. Press the
reset key again for at least 1 second.

5. The display screen again shows all
the segments of the display followed
by all the switched-off segments and
finally shows the display page where
the reset Reset Total is shown.

4.3

Dispensing with Flow Rate Mode Display

It is possible to dispense fluids, displaying at the same time:
The dispensed partial.
The Flow Rate in [Partial Unit / minute] as shown on the
following display page:

Procedure for entering this mode:

Wait for the Remote Display to go to Standby, meaning the
display screen shows Total only.
Quickly press the CAL key.
Start dispensing.
TP101

Issue No: 1 - 21/11/08

 The flow rate is updated every 0.7 seconds. Consequently,

the display could be relatively unstable at lower flow rates.
The higher the flow rate, the more stable the displayed value.
q

IMPORTANT! The flow rate is measured with reference to

the unit of measurement of the Partial. For this reason, in
case of the unit of measurement of the Partial and Total
being different, as in the example shown below, it should
be remembered that the indicated flow rate relates to the
unit of measurement of the partial. In the example shown,
the flow rate is expressed in Qts/min.

The word Gal remaining alongside the flow rate refers

to the register of the Totals (Reset or NON Reset) which
are again displayed when exiting from the flow rate reading
mode.
To return to Normal mode, press the CAL key again. If one
of the two keys RESET or CAL is accidentally pressed during
the count, this will have no effect.

q
IMPORTANT! Even though in this mode they are not

displayed, both the Reset Total and the General Total (Total)

increase. Their value can be checked after dispensing has

terminated, returning to Normal mode, by quickly pressing
CAL.
4.3.1 Partial Reset

To reset the Partial Register, finish dispensing and wait for the

Remote Display to show a Flow Rate of 0.0 as indicated in

the illustration then quickly press RESET.

5. calibration
5.1
Definitions

Calibration factor or k factor :

Multiplication factor applied by the system to the electrical

pulses received, to transform these into measured fluid units.
FACTORY K FACTOR:

Factory-set default factor. It is equal to 1,000. This calibration

factor ensures utmost precision in the following operating

conditions:

Fluid diesel fuel

Temperature: 20c

Flow rate: 10-120 litres/min

Even after any changes have been made by the user, the

factory k factor can be restored by means of a simple

procedure.

USER K FACTOR:
Customized calibration factor, meaning modified by

calibration.
5.2

Why Calibrate
When operating close to extreme conditions, such as for
instance with fluids close to acceptable range extremes (like
diesel fuel at low temperatures) or in extreme flow rate
conditions (close to minimum or maximum acceptable
values), an on-site calibration may be required to suit the real
conditions in which the TP101 is required to operate.

5.3
Calibration Procedure:
TP101 permits making quick and precise electronic calibration

by changing the calibration factor (k factor).
There are 2 different ways of calibration:

1. On-site calibration, performed by means of a dispensing
operation.

2. Direct calibration, performed by directly changing the k
factor.

To enter the calibration phases it is necessary to press and

hold down the CAL button.


Why enter the calibration phases?

To display the currently used calibration factor.

Return to factory k factor after a previous calibration with

user k factor.

Change the calibration factor using one of the two previously

indicated procedures.

In calibration mode, the partial and total dispensed quantities

indicated on the display screen take on different meanings

according to the calibration procedure phase. During the

calibration, the TP101 cannot perform any normal dispensing

operations. In calibration mode, the totals are not increased.
q

WARNING! The TP101 features a non-volatile memory. It

keeps the calibration and dispensing data stored even after
replacing new batteries or long periods of inactivity.

5.3.1 Display Of Current K Factor And Restoring Factory K

Factor

By pressing the CAL key while the

appliance is in standby, the display page

appears showing the current calibration

factor used.

If you are using TP101 with factory k

factor, the display page shown in the

diagram will be displayed, with the

word fact.

If one user k factor has been set, the

calibration factor set by the user (in our

example 0.998) will be displayed. The

word user indicates a calibration factor

set by the user is being used.
The flow chart

alongside shows the

switchover logic

from one display

page to another.

In this condition, the

Reset key permits

switching from User

factor to Factory

factor.
To confirm the

choice of calibration

factor, quickly press

CAL while User or

Fact are displayed.

After the restart

cycle, the meter

uses the calibration

factor that has just

been confirmed.
q

ATTENTION! When the Factory Factor is confirmed, the

old User factor is deleted from the memory.

5.3.2 In-field Calibration

This procedure calls for the fluid to be dispensed into a

graduated sample container in real operating conditions (flow

rate, viscosity, etc.) requiring maximum precision.
q

WARNING! For correct TP101 calibration, it is important to:

Completely eliminate air from the system before calibrating.
Use a precise Sample Container with a capacity of not less
than 5 litres, featuring an accurate graduated indicator.
Ensure calibration dispensing is done at a constant flow rate
equivalent to that of normal use, until the container is full.
DO NOT reduce the flow rate to reach the graduated area of
the container during the final dispensing stage (the correct
method during the final stages of sample container filling
consists in making short topups at normal flow rate).
After dispensing, wait a few minutes to make sure any air
bubbles are eliminated from the sample container. Only read
the Real value at the end of this stage, during which the
level in the container could drop.
If necessary, carefully follow the procedure indicated in 5.4.

5.4
In-field Calibration Procedure

5.4.1 TP101 In Stand by Mode

5.4.2 Press the CAL Key for 2 Seconds

TP101 enters calibration mode, shows

CAL and displays the calibration

factor in use instead of total. The

words FACT and USER indicate

which of the two factors is currently in use.
5.4.3 Press the RESET Key for 2 Seconds

TP101 shows CAL and the partial at

zero. TP101 is ready to perform

on-site calibration.
5.4.4

Dispensing into Sample Container

Without pressing any KEY,
start dispensing into the
sample container.

Dispensing can be interrupted and started again at will.
Continue dispensing until the level of the fluid in the sample

container has reached the graduated area. There is no need

to reach a preset quantity.

Indicated value

Real value

5.4.5 Press the RESET Key

TP101 is informed that the calibration

dispensing operation is finished.

Make sure dispensing is correctly

finished before performing this

operation.
To calibrate the TP101, the value indicated by the partial

totaliser (example 9.800) must be changed to the real value

marked on the graduated sample container.

In the bottom left part of the display an arrow appears

(upwards and downwards), that shows the direction

(increase or decrease) of the USER K FACTOR value change

when the operations 5.4.6 or 5.4.7 are performed.

Indicated value
Real value
TP101 calculates the new USER K FACTOR. This calculation

could require a few seconds, depending on the correction to

be made. During this operation the arrow disappears but the
CAL indication remains.

If this operation is performed after operation (5.4.5), without

changing the indicated value, the USER K FACTOR would be

the same as the FACTORY K FACTOR, thus it is ignored.
5.4.9

At the end of the calculation, the new

USER K FACTOR is shown for a few
seconds, after which the restart cycle
is repeated to finally achieve standby
condition.

ATTENTION! From now on, the indicated factor will become

the calibration factor used by the meter and will continue to
remain such even after a battery change.

5.4.10 TP101 stores the new calibration factor

and is ready for dispensing, applying the

newly defined USER K FACTOR.

5.5
Direct Modification of K Factor

This procedure is especially useful to correct a mean error

obtainable on the basis of several performed dispensing

operations. If normal TP101 operation shows a mean

percentage error, this can be corrected by applying to the

currently used calibration factor a correction of the same

percentage. In this case, the percentage correction of the

USER K FACTOR must be calculated by the operator in the

following way:
Example:
Error percentage found E% - 0.9 %

CURRENT calibration factor 1,000

New USER K FACTOR = 1,000 * [(100 ( - 0.9))/100]=

1,000 * [(100 + 0.9)/100] = 1.009

If the meter indicates less than the real dispensed value

(negative error) the new calibration factor must be higher than

the old one as shown in the example. The opposite applies if

the meter shows more than the real dispensed value (positive

error).
5.5.1 TP101 in STAND BY Mode

5.4.6 Press the RESET Key

Arrow direction changes. The operation

can be repeated if necessary.

5.4.7 Press the CAL Key

will then change quickly.

If the desired value is exceeded, repeat the operations from

point (5.4.6).
5.4.8 Press the RESET Key for 2 Seconds
TP101 is informed that the calibration

procedure is finished. Before doing this,

make sure the DISPLAYED factor is the

ACTUAL factor.

5.5.2 Press the CAL Key for 2 Seconds

TP101 enters calibration mode, shows

CAL and displays the calibration factor

being used instead of the partial. The

words FACT and USER indicate which

of the two factors (factory or user) is

currently being used.
