AUTO-RANGE TYPE MULTITESTER
MODEL AU-31
This is a circuit tester developed for measurement of small capacity
electric circuits based on our advanced design and engineering
technology. Electric circuits that can be measured include small
communication equipment, household appliances, lighting lines
(voltage), various batteries and other general electric circuits.
Before using your new tester, please read this instruction manual
that describes various useful methods of application and safe
operation.
[1] FEATURES
1. Auto range
A fully automatic range selector type eliminates a need for selection
of ranges for voltage or resistance measurement. The suitable
range is automatically set according to application.
2. Auto polarity
Both positive and negative polarities of DC voltage and current can
be automatically measured.
3. High input resistance
An input resistance as high as 10M
Ω
for measurement of both DC
and AC voltage minimizes measurement loss.
4. Series capacitor input
When measuring AC voltage in a DC and AC superimposed circuit,
the DC component can be cut and only AC voltage can be detected
and measured.
5. No need for 0
Ω
adjustment
There is no need for 0
Ω
adjustment, that is required when other
conventional testers are used.
