TANGAMPEREMETER MED ÅPEN TANGKJEFT
Frequency Test
1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana
plug into the V•Hz%•
Ω
•CAP• •TEMP positive jack.
2. Set the function switch to the Hz Position.
3. Read the Frequency value on the display.
4. The display will indicate the proper decimal point and value.
Temperature Measurements
1. Set the function switch to the TEMP position.
2. Insert the Temperature Probe into the negative COM and V•Hz%•
Ω
•
CAP
•
•TEMP
positive jacks, observing polarity.
3. Touch the Temperature Probe head to the device under test. Continue to touch the
part under test with the probe until the reading stabilizes.
4. Read the temperature on the display. The digital reading will indicate the proper
decimal point and value.
WARNING:
To avoid electric shock, be sure the thermocouple probe has been removed
before changing to another measurement function.
NON-CONTACT VOLTAGE (NCV) :
The NCV function works on any rotary switch position.
1. Test the detector on a known live circuit before use.
2. Hold the top of the meter very close to the voltage source as shown.
3. If voltage is present, the red light will long lighting.
LI-TEST
LI-test means Low input resistance. In the DCV/ACV function mode, pressing the function
switch “Low imp.250K
Ω
” can change the input resistance from
10
M
Ω
to about 250K
Ω
. It
may check the tangency state of the crunode.
NOTE:
Over rang protection:250V rms
VOLTSENSE Button
we need to continue to hold down this button and then The NCV function can work.
MODE Button
Only in Resistance. Continuity. Capacitance. Diode measuring mode, the MODE Button Can use.
DATA HOLD Button
To freeze the LCD reading, press the HOLD button. While data hold is active, the HOLD icon appears on the LCD.
Press the HOLD button again to return to normal operation.
Note:
in Resistance. Continuity. Capacitance. Diode measuring mode, the HOLD button
Can’t use.
LCD Backlight Button
The LCD is equipped with backlighting for easier viewing, especially in dimly lit areas. Press the HOLD button for
over 1 second to turn the backlight on. Press again for over 1 second to turn the backlight off.
