SAFETY INFORMATION
EMC: Conforms to EN61326-1.
The following safety information must be observed to insure maximum personal safety during
the operation of this meter:
Use the meter only as specified in this manual or the protection provided by the meter might be
impaired.
Do not use the meter if the meter or test leads look damaged, or if you suspect that the meter
is not operating properly.
Never ground yourself when taking electrical measurements. Do not touch exposed metal
pipes, outlets, fixtures, etc., which might be at ground potential. Keep your body isolated from
ground by using dry clothing, rubber shoes, rubber mats, or any approved insulating material.
Turn off power to the circuit under test before cutting, unsoldering, or breaking the circuit.
Small amounts of current can be dangerous.
When using the probes, keep your fingers behind the finger guards on the probes.
Measuring voltages which exceed the limits of the multimeter may damage the meter and
expose the operator to a shock hazard.

OPERATION
1.7 ON/OFF SWITCH: Power.
1.8 LCR / DCR / ( LCR AUTO CHECK > 2 sec ) Button
•Shift " L ( Inductance ) " " C ( Capacitance ) " " R ( Resistance ) " " DCR ( DC
Resistance ) " " DIOD E TEST " ranges.
•Depress this button for more than 2 seconds to enter LCR AUTO TEST mode.
•Depress this button again for more than 2 seconds to exit.
•Note: In the LCR Auto Check mode, the " AUTO " symbol will flash continuously on the
display.
1.9 DQR ( SER / PAL > 2 sec ) Button
Use this button to shift between dissipation (D) and equivalent reisistance (R) [ESR or RP
depending on the PAL or SER mode you are in] when in capacitance mode (C). When you are
in inductance mode (L), this button will switch you from quality factor (Q) and equivalent
resistance (R). In resistance mode (R), this button will only switch you between PAL and SER.
In DCR mode this button will have no function.
Depress this button for more than 2 seconds to enter " SER ( Series test mode ) " PAL (
Parallel test mode ) ".
The SER or PAL will be blinking while it is in changing mode. To set the mode depress this
button again for more than 2 seconds to exit. The PAL mode does not seem to lock in when
you switch over to it. It just keeps blinking. Just moved thru the LCR button until you come
back to C and it should be locked in then. One the mode is locked in you can press the button
to shift thru D, ESR(or RP), Q.
Auto-detection is defaulted for the SER ( series test mode ) and PAL ( parallel test mode ).
SER ( series test mode ) defaults for resistance to be measured lower than 10kΩ; and PAL (
parallel test mode ) defaults for resistance to be measured higher than 10kΩ. Depressing

DQR/SER/PAL button can settle to either SER ( series test mode ) or PAL ( parallel test mode
).
1.10 FREQ (LEVEL 0.1V/0.5V RMS > 2 sec) Button
•Shift " 100Hz " " 120Hz " " 1kHz " "10kHz" test frequency.
•Depress this button for more than 2 seconds to enter " 0.1V " RMS " 0.5V " RMS test
signal am plitude ( LCR mode ) .
1.11 Data Hold Feature
•Press [HOLD] button to toggle in and out of the Data Hold mode.
•In the data hold mode, the "HOLD" annunciator is displayed and the last reading is held
on the display.
•Press [HOLD] button again to release the hold and current readings are once again
displayed.
1.12 Inductance ( L ) Measurements
•Set the function " L " position.
•Touch the probes to the Inductance.
•Read the Inductance directly from the display.
•In the Inductance ( L ) mode, if a capacitor is measured by mistake, the meter will show
a negative value on the display to indicate the mistaken measurement.
•When performing tests, do not touch the metal part of the tweezers by hands, otherwise
the readings would be disturbed and inaccurate.
1.13 Capacitance ( C ) Measurements
•Set the Function to " C " position.
•Touch the probes to the capacitor.
•Read the capacitance directly from the display.
•Discharge the capacitor before taking capacitance measurements.
•In the Capacitance ( C ) mode, if an inductor is measured by mistake, the meter will
show a negative sign in front of the reading on the display to indicate the mistaken
measurement.
•When performing tests, do not touch the metal part of the tweezers by hands, otherwise
the readings would be disturbed and inaccurate.
1.14 Resistance Measurements
•Set the function to " R " or " DCR " position.
•Turn off power to the circuit under test. External voltage across the components causes
invalid readings.
•Touch the probes to the test points. In ohms, the value indicated in the display is the
measured value of resistance with proper decimal point and annunciate or indication.
•When performing tests, do not touch the metal part of the tweezers by hands, otherwise
the readings would be disturbed and inaccurate.

1.15 Testing Diodes
•Set the Function to " " position.
•Turn off power to the circuit under test. External voltage across the components causes
invalid readings.
•Touch probes to the diode. A forward-voltage drop is about 0.6V ( typical for a silicon
diode ).
•Reverse probes. If the diode is good, " OL " is displayed. If the diode is shorted, a value
near 0mV will be displayed.
•If the diode is open, " OL " is displayed in both directions.
•Audible Indication: Less than 0.05V.
1.16 Auto Power off
•Auto power off: approx. 30 minutes.
•After auto power off, ON/OFF switch to restart the meter.
•To disable this feature press and hold the ( HOLD ) button while moving slide switch
from “OFF” to “ON.” The auto power off feature is now disabled. Note " APO " indicator
is missing from the LCD.
•To enable this feature press and hold the ( HOLD ) button while moving slide switch
from “ON” to “OFF.” The auto power off feature is enabled. “ APO” should now be
visible on the LCD.
CLEANING
Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Dirt or
moisture in the terminals can affect readings.
BATTERY REPLACEMENT
Remove the batteries if the meter will not be used for an extended time.
Power is supplied by 3 volt button-type lithium batteries x2, CR2032. " " appears on the LCD
display when replacements are needed.
1. Set the Function Switch to OFF.
2. Remove battery cover screw.
3. Slide off battery cover and change battery.
4. Replace battery cover and screw.
