 2. INTRODUCTION
This manual describes how this product works and how to get the most out of it in
terms of performance.
The FS-D weighing indicator is used to build high performance check weighing
scales. It has similar specifications and functions as an indicator of the FS-i series.
Please refer to the instruction manual for the FS-i supplied with the FS-D.

The FS-D indicator has the following features.

‰ The indicator can be used to build platform scales from 6 kg (15 lb) capacity to 1500
kg (3500 lb) capacity.
‰ The indicator can drive up to 4 x 350 Ω load cells.
‰ Three weight display resolutions are available, 1/3,000, 1/6,000 (~1/7,500) and
1/12,000 (~1/15,000) to cover various applications.
‰ Weighing units are kg (kilogram), g (gram), lb (pound), oz (ounce), and lb-oz
(pound and ounce). However, the FS-D set to a capacity higher than 30 kg (70 lb)
does not have all of them. Refer to “11-1. Capacity and minimum display” in detail.
‰ Waterproof to IP-65 specifications.
‰ Constructed from stainless steel for harsh working environments.
‰ Large liquid crystal display with back lighting and analog sweep display of 60
segments with back lighting.
‰ AC power source (100V ~ 240V), and an optional SLA (sealed lead acid) battery is
available for operation where AC power is not available.
‰ Built in comparator lights with large and bright red, green and yellow LEDs for better
visibility.
‰ Two modes of comparator operation, Target weight setting and Upper / Lower limits
setting.
‰ Take-away check weighing with auto-tare function.
‰ Optional serial data and comparator relay interface.

4-1. Precautions for Installing the Indicator
‰ Ground the indicator so that the user will not be subjected an electric shock.
‰ Do not handle the main power cord with wet hands.
‰ The AC plug is not water-resistant. Install it in an area where it does not get wet.
‰ Do not install the indicator where there is flammable or corrosive gas present.
‰ Do not install the indicator under water.
‰ Do not pull, fold or arrange cables forcibly.
‰ Use shielded cables for all connections.
‰ Ground the platform to be connected to the indicator to avoid a risk of electric shock.

Read the section “CAUTION” in the instruction manual of the FS-i to

understand the conditions and precautions for installation, operation and
cleaning the indicator.

4-2. Load Cell Connections

‰ Solder the load cell cable to the connector plug (1JMNJW-165-PM7) provided with
the FS-D and connect it to the connector on the bottom of the FS-D.
1. Use the supplied hexagonal wrench (1.27 mm / 0.05 inch) to loosen the setscrews A

7. Connect the connector plug to the
load cell connector on the bottom
of the display pod.

4-3. Verifying Load Cell Output and Input Sensitivity

The input sensitivity is 0.2 µV/division or more. When designing a weighing scale, the
load cell output voltage should satisfy the input sensitivity of the indicator. Or the scale
should be designed so that the following calculating formula is satisfied.
‰ In order to achieve a scale with stable performance, select the input sensitivity as
large as possible.
Calculating formula:
A: Rated capacity of load cell (kg)
E× B×d B: Rated output (mV/V)
0.2 ≤ d : Min. display (smallest of kg) / scale division
A×n
E: Excitation voltage (mV) = 5000 mV for FS-D
n: Number of load cells
Example of calculation:
In the case of designing a scale with a capacity of 60 kg, using a load cell with a
rated capacity of 100 kg and rated output of 1 mV/V:
Load cell capacity: A = 100 kg
Rated output: B = 1 mV/V 5000 × 1 × 0.005
Set function setting C02-3, then = 0.25 > 0.2
Min. display (smallest): d = 0.005 kg 100 × 1
Excitation voltage: E = 5000 mV
Number of load cell: n=1

Calibration (CAL) switch

7-1. Calibration using a weight
1. Warm up the indicator with a weighing platform connected for at least half an hour.
‰ Change the user function setting “f01” or place something on the platform to
disable the auto power-off function.
‰ When turning the power on and the indicator may display ------- ,
press the PRINT/ENT key to proceed to the weighing mode.
2. Press and hold the calibration (CAL) switch until
Cal appears, and release the switch.
‰ Press and hold the 0 key for about 5 seconds, then you
-00Cal00
can also enter the calibration mode (when “C01-0” is set).
‰ Press the ON/OFF key or (CAL) switch to exit without
calibration.
3. Press the PRINT/ENT key, then the gravity
acceleration value will be displayed. -009.7985
‰ It is not necessary to set the gravity acceleration value
when calibrating the indicator with a calibration weight
at the place where it is to be used. (See the next
section about the gravity acceleration correction.)
4. Press the PRINT/ENT key, then Cal 0 will be
displayed. -00Cal00
5. Make sure that there is nothing on the platform, and wait
until the STABLE indicator turns on.
6. Press the PRINT/ENT key. The indicator inputs the
zero point, and the display shows 5pn 1 and the -05pn010
weight value for calibration (SPAN calibration).
‰ The weight value is equal to the capacity. When you
enter with “kg” or “g” mode, then the value is “kg”.
Entering with “lb” or “oz”, then “lb”.
-00030.00
12
 ‰ If you need ZERO calibration but do not need SPAN
calibration, turn the power off to exit from the calibration
procedure.
7. To calibrate with a different weight, change the
displayed value using the 10-key pad.
‰ If you enter the wrong number, press the C key. The
-00020.00
value returns to the capacity and enter the number again.
8. Place a calibration weight on the platform with the same
value as displayed, and wait until the STABLE indicator
turns on.
9. Press the PRINT/ENT key. The indicator calibrates
SPAN and end will appear. Remove the weight -00end00
from the platform, and turn the power off.

‰ Note
The value set in step 7 will be cleared after the power is switched off.
If the indicator will be moved to another location, set the gravity
acceleration value for the current location and calibrate the indicator
according to the procedure above. See the next section to set the value.

7-2. Gravity acceleration correction

When the indicator will be moved to different place from the calibration location, it
should be calibrated using a calibration weight.
But if a calibration weight is not available, the gravity acceleration correction will
compensate the indicator. To use this function, set the gravity acceleration value to the
value of the location where the calibration will be done. Refer to the gravity
acceleration map appended to the instruction manual of the FS-i series.

1. At step 3 of the previous section “7-1. Calibration using

a weight”, enter a new value using 10-key pad.
‰ The integral part “9” is fixed, enter the value after the
-009.8050
decimal point.
‰ If you hit the wrong number, press the C key. The
value returns to the original number. Enter the number
again.

2. Press the PRINT/ENT key, then Cal 0 will be

displayed. -00Cal00
3. Go to step 5 of “7-1. Calibration using a weight”.

13
 8. AUTO-TARE FUNCTION
The FS-D has an auto-tare function to be used with the comparator function enabled.
If the weight value is within the OK range and stable for a preset time, then the
indicator will automatically tare the weight and show zero. The Function “f22”
designates the timing to tare automatically. See “9. ADDITIONAL INFORMATION”
about the added F-Function settings related to the auto-tare function.
‰ To use the auto-tare function, set the function settings below.
f08-1: Compare all weighing data (other settings may be used depending on
the application).
f21-1: Auto-tare function enabled.
f22-0 ~ 9: Select the timing to tare automatically to avoid the wrong tare
operation, for example; too early to tare, to take a longer time to go to
the next weighing and so on.

‰ Take-away check weighing:

Take-away check weighing (negative comparison) is the way to compare the
negative weight taking away material from a container. Set the Function “f24-1”
together with the auto-tare function enabled “f21-1”. In this operation mode, the
indicator operates as “take-away the material” Æ “OK and stable” Æ “auto-tare” Æ
“take-away the material” Æ ······.
In this setting, the polarity of the target weight and the upper / lower limit weight are
ignored and the indicator shows the comparator results as below.
f07-1: -(|Target|+HI limit) -(|Target|-LO limit)
f07-0: -|Upper limit| -|Lower limit|
Negative value Net 0 Weight display

HI OK LO
Note To start the take-away check weighing, be sure to use the TARE key to tare
the weight of the container filled with material. The ZERO key may zero the
display, and the indicator goes below the zero point by taking out the material.
Then, the auto-tare function does not work.

‰ When the Function “f23-1 Tares the initial (container) weight.” is set:
To start the auto-tare function application, usually the container (filled with material) will
be placed on the weighing pan and its weight must be tared using the TARE key.
When the Function “f23-1” is set, the indicator will tare the initial (container) weight
automatically.
Remove all load on the weighing pan to return to the zero point, the tare weight will be
automatically cleared. If the indicator could not return to the zero point because of a
zero shift, press the ZERO key to clear the tare weight.

‰ If the indicator is equipped with the optional RS-232C interface, the OK weighing data
only can be sent out automatically. Set the Function setting “f06-7 Auto-print mode
+/- data”.

Multi-connection with Print key mode (new function)

This is one of the applications when a PC and more than one FS-D are connected.
The indicator will prepare the weighing data by pressing the PRINT key first and will
send out the prepared data after receiving a command from the PC.
1. Set the Function “f06-5” for all of the indicators.
2. Weigh something and wait for the STABLE indicator to turn on (the indicator having
f18-##).
3. Press the PRINT key, the indicator will temporarily store the weight data and turn
the PRINT indicator on.
‰ The indicator does not accept the PRINT key while the PRINT indicator on.
4. Send the “@##S” command to the indicators from the PC.
5. The indicator (f18-##) will respond to the command to send the weight data in
memory and turn the PRINT indicator off.
The address ## = 23 (f18-23).
