Resistance Measurement
After the booting auto-
inspection is completed, it shows "OL Ω" and
will be able to proceed with resistance measurement. At this point,
press the trigger and open the jaws, clamp the target loop, reading
to get the resistance value.
If the user thinks it necessary, the test can be done with the ring as
shown in the following figure 5. Its show value should be consistent
with the normal value on the test ring (5.1Ω).
The normal value on the test ring is the
value at a temperature of 20°C.
It is normal to find the difference of
numerical 1 word between the show
value and the nominal value,
For instance: If the nominal value of
test ring is 5.1Ω, it would be normal
showing 5.0Ω or 5.2Ω. Figure 5
It shows "OL
Ω‖, indicating that the
measured resistance value exceeded
the upper limit of Meter, see Figure 2.
It shows "L0.01
Ω‖, indicating that the
measured resistance value exceeded the lower limit of Meter, see
Figure 6.
