3.2.3 Electric resistance measurement
To avoid the meter or the measured equipment from damage,
do not attempt a resistance measurement unless the operator
has already cut off all power sources for the circuit to be
measured and fully discharged all high-voltage capacitors.
Ohm is the unit of electric resistance ( ).
The measuring ranges of electric resistance of this meter are 600.0 ,
6.000k , 60.00k , 600.0k , 60.00M and 600.0M ,
Measurement of electric resistance
1. Turn the rotary switch to the appropriate position.
2. Connect the test lead in black and test lead in red to COM input socket
and V/ input socket respectively.
3. Use another two ends of the test lead to measure the electric
resistance of the circuit to be measured.
4. Read the measured electric resistance value on LCD screen. Notes :
◼
The measured value of the electric resistance of the circuit differs a bit
from the rated value of the electric resistance.
◼
To ensure measurement accuracy, in attempting a low resistance
measurement, first put two pen-shaped meters in short circuit and
capture the resistance reading of these short circuits. Then subtract
the aforesaid reading from the measured resistance.
◼
At 60M /600M position, you have to wait a few seconds before the
reading grow stable. This is quite normal for a high resistance
measurement.
◼
When the meter is in open circuit, the display unit will show "OL" that
indicates the measured value is over the measuring range.
