setter(Refer to Fig. 6 in [16] MAINTENANCE) This tester
employs the constant voltage method for measurement of
resistance and there is no need of 0
Ω
adjustment for normal
measurement.
To cancel resistance of the test leads in measurement in the x 1
Ω
range, turn the 0
Ω
setter in the battery case with the test pins
shorted CW or CCW to the 0
Ω
line at the right end of the
Ω
scale.
Also if the 0
Ω
point has moved over a long period of use, make
0
Ω
adjustment in the same manner.
Applicable voltage and current in measurement of resistance
Measurement of resistance is conducted with the internal power
source. About 1.2V is output as follows: + to the (-COM) terminal
and - to the ( ) terminal. When this voltage is applied, the
following current flows. Refer to the following table when
measuring polarized resistors such as transistors and diodes or
resistors whose values change according to intensity of current to
flow.
