About measurement mode
Measurement mode can be switched by mode switch.
The following constant measurement mode is set at shipment.
<Always measuring mode>
The measured value is displayed at all times.
It automatically turns off in 35 seconds from the start of measurement.
<Measurement value hold mode>
Fixed the measurement value after 15 seconds from the start of measurement, turn OFF
after displaying for 5 seconds.
When the object to be measured is in the vicinity of the switching point of applied voltage
(around 1.00 x 10
6
Ω
), the applied voltage may go back and forth between 100 V / 10 V
and the measurement result may not be stabilized.
In this case, please adopt measurement result narrowed down to either applied voltage.
Measurement value In the hold mode, it is sometimes fixed as a result of an unintended
applied voltage, so we recommend using it in the continuous measurement mode.
How to switch measurement mode
Remove the protective case and remove the 4 screws
on the back side, the main case opens.
When the switch at the upper right of the battery box
is tilted to the left, it is always in measurement mode,
and when it is tilted to the right, it enters measurement
value hold mode.
After switching, install the main unit case and the
protective case in reverse order.
When the object to be measured is high resistance (× 10
10
to 10
11
Ω
or more), it takes
time to stabilize the measured value.
Because measured values may not be stabilized within 15 seconds, we recommend you
to use in constant measurement mode when measuring high resistance.
Measurement value When using hold mode, please measure twice or more and adopt
later measurement result.
The current mode can be confirmed with the 15 S mark.
