In measuring, if the length of test line is not enough, you can
use lead having same size diameter to extend it.
3. Measurement
Well connected the test line as fig. 2, closed power switch,
power indicator lights, and press the "start/stop" button, then the
display shows "E0000". According to the measured value select
appropriate resistance gear range, press its switch, then its
indicator lights, the four and half bits digital stably shown in LCD is
the measured resistance value. When reading resistance value,
please pay attention to the unit of selected range (mΩ / Ω / kΩ).
Measuring large inductance such as power transformer, you’d
better keep the coils not measured short-circuited to avoid
electromagnetic interference.
4. Discharge
Finished measurement, you can directly disconnect main
power. For measuring inductive object, it is not recommended
immediately disconnect the wiring after disconnected the power,
the instrument should be left to continue discharge. General
discharge time is at least 20 seconds; otherwise the EMF of the
inductance could endanger personal safety.
