Resistance measurement
Warning!
To avoid electricity shock, before the resistance measurement, user shall first cut off (taking out the
battery/ remove the power line) the power of the device to be tested and discharge the capacitor of the
power.
1. Plug the banana plug of the black test line into the negative COM socket and the banana plug of the red test line
into the positive resistor
socket.
2. Rotate the rotary knob to select “
” measurement function. Then, a sign of “RESISTANCE” will appear
on the top of the screen to remind user that the function of resistance measurement is currently available.
3. Bridge the test lead over the circuit or component to be tested. The tested part online is better to be removed
from the original circuit connection, so as to ensure other part of the circuit will not affect its correct reading.
4. The instrument will display the value of resistance, unit
and decimal point.
The operation option menu of resistance measurement is as follows:
Relative value mode
Peak value holding mode
Extended measuring function
REL
P-H
SEL
F1
F2
F3
a. Press F1 button (REL) to enter into relative value mode.
b. Press F2 button (P-H) to enter into peak value holding mode.
c. Press F3 button (SEL) to enter into extended functions: diode test, continuity test and capacitance measurement.
