Page 10
The DRM-100 measures resistance in 3 ranges, which are
auto-selected depending on the test current and
discovered resistance. The ranges are:
0 µ
Ω
to 1999.9 µ
Ω
for currents from 10 to 100A
0 m
Ω
to 19.999 m
Ω
for currents from 10 to 100A
0 m
Ω
to 199.99 m
Ω
for currents of 10A only
The duration of the test is selectable from 10 to 60
seconds for all currents.
Continuous Resistance Test
The instrument can be set to provide a continuous test
current, so that resistance may be continuously monitored.
This is achieved by setting the test time to continuous (
∞
).
If this value is selected, the instrument selects a test
current of 20A automatically. The DRM-100 can supply
20A indefinitely. The test is started and stopped by
pressing the START/STOP button.
If the test current is afterwards selected to other than 20A,
the continuous test time is immediately cancelled and
defaulted to 10 seconds.
