• Use the meter only as specified in this instruction manual. Otherwise
the meters protection may be impaired.
• Never use this meter on a circuit with voltages greater than 750Vrms @ 50/60 Hz.
• Do not operate the meter if the body or test leads look damaged.
• Check the function selector range switch and make sure it is at the correct position before each measurement is taken.

Data Hold Function
Press the “HOLD” button at any time to hold the current reading. To
release the data being held, simply press the “HOLD” button again.
Peak Hold Function
This meter is designed with 1ms peak hold function at ACA, ACV, DCA
and DCV ranges. Before performing a peak hold operation, a calibration
process must be completed first.
To do this, press and hold the peak button for 2 seconds. “CAL” will display on the LCD and the offset will be calculated and kept in the meter.
After the calibration is complete, you can choose P+ or P- by pressing
the “PEAK + HOLD” button to keep the peak reading. To return the meter
back to normal operation, press the “PEAK” button for 2 seconds.
When the function range changes, the meter will require another calibration for peak measurement.
MAX/MIN Function
This meter is designed with a MAX/MIN function at ACA, ACV, DCA and
DCV ranges.
Press the “MAX/MIN” button once to set the meter to the MAX mode.
Press it once again to set the meter to MIN mode. Press it once again and
the meter will display the present reading and will continue tracking the
MAX and MIN changes. This mode will also be indicated with the blinking
“MAX MIN” symbol.
Set the meter back to normal operation by pressing the “MAX/MIN”
button for more than 2 seconds.
REL Function:
This meter is designed with REL function at ACA, ACV and DCV, DCA ranges.
Press the “REL” button to change the zero to the current reading and the
relative value will show on the LCD. Press it once again and the meter
will display the relative zero point. This mode will also be indicated with a
blinking “REL” symbol.

Measurement Procedures
Current Measurement
Switch the main function selector to proper current range.
ACA
Open the clamp by pressing the jaw-opening handle and insert the cable
to be measured into the jaw. Choose AC current measurement by pressing the “AC/DC” button for ACA readings.
DCA
To measure DC current, choose DC measurement by pressing the
“AC/DC” button. Wait for the reading to stabilize then press the “REL”
button to reset the reading. Once completed, insert the cable to be
measured into the jaw and read the value.
Notes: Before taking this measurement, disconnect the test leads from the
meter for safety. If the reading is difficult to read, push the “HOLD” button
and read the result later.

Voltage measurement
Switch the main function selector to Voltage Range. Connect the Red test
lead to the “+” terminal and the Black one to the “COM” terminal. Choose
AC or DC by pressing the AC/DC button. Measure the voltage by touching
the test lead tips to the test circuit where the value of voltage is needed.
Read the result on the LCD panel.
Resistance measurement
Switch the main function to the “Ω” range,
verify that the power line is disconnected from
the system. Connect the Red test lead to the
“+” terminal and the Black one to the “COM”
terminal. Connect the tips of the test leads to
the points where the value of the resistance is
needed. Read the result on the LCD panel.
Note: When measuring the resistance value of
a circuit system, make sure the power is off
and all capacitors required are discharged.

Continuity Test
Switch the main function to
the “
” range, verify
that the power line is
disconnected from the
system. Connect the Red
test lead to the “+” terminal
and the Black one to the
“COM” terminal. Connect
the tips of the test lead to
the points where the value of
the conduction condition
is needed. If the resistance
is under 100Ω, the beeper
will sound continuously.

Diode Test
Switch the main function to the
“
” range, verify that the
power line is disconnected from the
system. Connect the Red test lead to
“+” terminal and the Black one to the
“COM” terminal. Connect the tips of
the Red test lead to the anode side and
the Black test lead to the cathode side
of the diode being tested. Read the
forward Voltage (Vf) value on the
LCD panel.
If the polarity of test leads are reversed
with diode polarity, the digital reading will show “OL”. This can be used
for distinguishing between anode and
cathode terminals of a diode.

Frequency measurement
from the terminals
Switch the main function to the “Hz”
range. Connect the Red test lead to the
“+” terminal and the Black one to the
“COM”. Connect the tips of the test
leads to the points where the frequency
of the voltage signal is required. Read
the value one the LCD panel.
Frequency measurement
with the clamp
Switch the main function to the “Hz”
range. Open the clamp by pressing
the clamp-opening handle and insert
the cable to be measured into the
clamp. Close the clamp and you will
find the reading on the LCD panel.
Note: When taking frequency
measurements, you should either use
the terminal signal or clamp signal
but not both. If both sources are
applied an error reading will occur.

Battery Replacement
1) When the battery voltage drops below the proper operation range the
symbol will appear on the LCD display, indicating that the battery
needs to be changed.
2) Before changing the battery, switch the main function to “OFF” and
disconnect the test leads.
3) Open the back cover using a screwdriver.
4) Replace the old battery with a new 9V battery.
5) Close the back cover and fasten the screws using a screwdriver.
Product Maintenance
WARNING!
Before opening the meter, disconnect both test leads and never use
the meter before the cover has been reinstalled and fastened.
To avoid contamination or static damage, do not touch the circuit
board without proper static protection.
Notes:
• If the meter is not going to be used for a long time, take out the battery and
do not store the meter in high temperature or high humidity environment.
• When taking current measurements, keep the cable at the center of the
clamp to yield a more accurate test result.
• Repairs or servicing not covered in this manual should be performed
only by qualified personal.
• To clean the meter, periodically wipe the case with a dry cloth. Do not
use abrasives or solvents on these instruments.
