After the power-on self test is completed, the large middle digit shows
“OLΩ” and resistance measurement can be performed. At this point,
withhold the trigger, open the jaws, clamp the circuit under test, and read
the resistance value.
The large middle digit shows "OLΩ", indicating that the measured
resistance exceeds the upper limit of the clamp meter.
The middle large number shows "L0.01 Ω", indicating that the
measured resistance exceeds the lower limit of the clamp meter.
Resistance + clock mode:
The measured resistance loop resistance
is 0.51Ω.
The number of save groups is 1 and the
loop ground voltage to be measured is 0.0V.
Resistance + clock mode:
is normal. The check ring has two resistances of 1
Ω and 10Ω.
