Introduction
This 19,999-count L/C/R hand-held meter is a special
microprocessor-controlled meter for measuring functions of
inductance, capacitance and resistance. Extremely simple to
operate, the instrument not only takes absolute parallel mode
measurements, but also capable of series mode measurement. The
meter provides direct and accurate measurements of inductors,
capacitors and resistors with different testing frequencies. It is
selectable for auto and manual ranging.

How To Operate
Caution
◆
When measuring within a circuit, the circuit must be
de-energized before connecting the test leads.
◆
The instrument that used in dusty environment should be
wiped and cleaned regularly.
◆
Do not leave the instrument exposed to direct heat from the sun
or beat source for long periods.
◆
Before removing the cover, ensure that the instrument is
disconnected from any circuit and in power "OFF" position.
Note:
For achieving optimum precision for all L, C and R
measurements at either the highest or lowest ranges, it is
recommended to calibrate the meter before testing.

Operating Instructions
Data Hold
This data hold function allows the operator to freeze the display.
To enter this mode, press the "HOLD" pushbutton; press again to
release.
Static Recording
Press the "REC" pushbutton for more than one second to enter the
static recording mode. The maximum and minimum
readings are then stored in memory, while a beeping tone is
produced when a new tested value has been recorded. Push
the same button to cycle through the maximum, minimum and
average of the present readings.
The MAX, MIN or AVG indicators will display on LCD will turn
on to indicate what value is being displayed. Whenever the
"MAX AVG MIN" indicators appear on the LCD simultaneously,
the display reading is always a present value. To exit this mode,
press and hold the pushbutton for more than one second.
Notes:
1. Static recording captures only stable values and updates the
memory; it will not record any "OL" (overload) value for any of
the L/C/R functions. In addition, the meter will not record which
values are below 50 counts in Capacitance measurement.
2. Static recording is only available in manual ranging; however,
activation while in auto-ranging will automatically set meter to
manual ranging and cause calibration prompts to be displayed in
the recommended ranges.

Test Frequency
Relative
Press the "REL" key to enter the relative mode and stores the
display reading as a reference value. It will then display all
subsequent readings in relative to reference value. Press the button
again to exit the relative mode.
Notes:
1. The relative mode can’t be activated if the display value is
either "OL" or "0000".
2. Relative mode is only available in manual ranging; however,
activation while in auto-ranging will automatically set the meter
to manual ranging and cause calibration prompts to be displayed
in the recommended ranges.
3. The relative mode cannot be activated if the meter is set at auto-
ranging with data hold activated.
Tolerance
There are 1%, 5%, 10% and 20% tolerance range. To enter this
tolerance mode, insert the appropriate component as a standard
value into the socket or connect the component to the test probes,
then press the "TOL" pushbutton to set this value, as the standard
reference tolerance. Similarly, any value which appears on the
LCD display, such as DH or MAX/MIN/AVG, can be used as a
standard value to sort components. Press this button again to cycle
through 1%, 5%, 10% and 20% tolerance as desire.
This function is designed for convenient component sorting. An
audible tone of “Be-Be-Be” will sound whenever the component
under test exceeds the setting tolerance. Conversely, a single tone
of “Be” indicates the component is within the setting tolerance.
1
Notes:
1. The tolerance mode can’t be activated if the tested display is
either "OL" or "0000"; nor can it be activated the tested
capacitance value is below 10 counts.
2. Tolerance mode is only available in manual ranging; however,
activation while in auto-ranging will automatically set the meter
to manual ranging and cause calibration prompts to be displayed
in the recommended ranges.
3. The tolerance mode can’t be activated if the meter is set at auto-
ranging with data hold mode activated.
4. For 20% selection is available on Model-A only.
When the meter detects that the protective fuse is open, the "FUSE"
character will appear and an internal beep will sound continuously.
In this situation, none of the function keys can be operated and all
other meter functions will be discontinued. Fuse replacement is
required.
1
Calibration
Notes:
1. Changing measurement frequencies is handled the same as
selecting a different hardware range, and so automatic
calibration prompts will be displayed in the recommended
ranges.
2. Be sure to use same testing position after short calibration.

Auto Power Off/ Disable Auto Power Off
When the meter has not been used for five minutes after the last
operation was made, a long "beep" tone will sound. The meter will
then automatically enter a "sleep" mode and there will be no
display on the LCD. To reactivate the meter, simply press any
pushbutton. After re-activating.
When the meter is to be used for long period, the auto power-off
can be disabled by pressing and holding "L/C/R" button while
turning meter ON. Release the button, and press any button again.
The symbol will be disappeared to
confirm that the auto power off has been disabled.
By using a 12V AC adaptor as an optional power source, auto
power off is disabled automatically.
When the " " symbol flashes on the display, the battery voltage is
below normal working voltage and is weakening. Replace battery with a
new one to maintain accuracy of the meter.
Press and hold " " key for more than one second to toggle backlit
ON/OFF.

Communication
1. Fixes one side of cable to the meter, and the text side shall be
facing up. To connect the 9-pin’s terminal of cable to
communication port 1 or 2 of personal computer. See the
Figure-8.
2. Press "RS232" button to enable this interface. You will find that
the symbol of “ ” is lit on the display.
3. Execute the software to take the data for your applications.
4. Be sure to push the snap ends on the cable of meter side for
removing the cable.
The text side shall be facing up.

MAINTENANCE
WARNING
To avoid electrical shock, do not perform any service
unless you are qualified to do so.
SERVICE
If the instrument fails to operate, to check battery and test leads,
and replaces them if necessary. If the instrument still can’t work,
double check operating procedure as described in this instruction
manual. When servicing, use specified replacement parts only. The
meter must be completely turned off while replacing either the fuse
or battery.
Battery Replacement
2
Fuse Replacement
The meter can self-detect if its input protective fuse is either open
or damaged. In this case, the LCD will display the
symbol "FUSE" and an audible beep will sounds continuously,
warning the user to replace the damaged fuse to maintain the
accuracy of measurement. While replacing the fuse, the
power of the meter must be completely shut off.

Cleaning the Meter
WARNING
To avoid electrical shock or damaging the meter,
never get water inside the case.
