5-7 Diode Test & Continuity Measurement
Connect red test lead to the "
•
" terminal and black test lead to the " COM" terminal.
Set range switch to the diode test position " " .
Connect the red test lead to the anode side and black test lead to the cathode side of the diode being tested.
Read forward voltage ( Vf ) value on LCD.
If the test leads is connected rather than procedure(4), the digital reading should nearly equal to the reading in the open circuit condition. This can be used for distinguishing anode and cathode poles of a diode.
When the reading is below 0.050V, it will be indicated by a continuous beeping.
5-8 Peak Detection Measurement

Set Function / Range Switch to desired
•
A or
•
V range.
Set the clamp Meter into the " PEAK HOLD " mode by pushing the "YELLOW" button. The LCD will display " P+ P- ".
Press the “PEAK” button to enter PEAK mode. LCD will display “P+ MAX” or “P- MIN”. The “PEAK” button is toggle selector the P+ and P- value.
Press the “PEAK” button for two seconds to exit the PEAK mode.
Follow this procedure for AC Voltage and current measurement.
The displayed reading is the positive peak value or negative peak value of a surge in current or a voltage transient pulse.
Because the surge transient pulse is usually asymmetric.
5-9 Operation Of Data Record And Read
Singly Data Record
The clamp meter can store 25 data record in memory.
Once the button is pressed, the data number and
RECORD symbol will be shown on LCD. If the memory is full, the FULL signal will be shown on LCD when the record button is pressed.
Singly Data Record
Press “Yellow” button until the READ symbol shown on LCD, then
Press “
•
” button to read previous data. Press “
•
” button to read next data. Press “Yellow” button again to exit.
Continue Data Record
The full memory size got 4000 records. To start recording data, press the RECORD button until 2 “beep” sounds heard and “RECORD” symbol will be shown on LCD. To stop recording data, press the RECORD button again until the RECORD symbol disappears.
Continue Data Record
With the connection of RS-232 interface & computer P.C. software.

Clear data logger
To clear the memory of the meter, power off the meter, then hold RECORD button and then power on it until the
LCD shows CLr.
VI. BATTERY REPLACEMENT
WARNING
To prevent electrical hazard or shock, turn off clamp meter and disconnect test leads before removing back cover.
As battery power is not sufficient, LCD will display
Replacement with one new battery type 9 V is required.
.
Set Range switch to OFF position.
Use a screwdriver to unscrew the screw secured on back cover. Take out the batteries and replace with one new battery Type 9V.
Place back cover and secure by a screw.
