Operation
Do not touch the electrodes during measurement. There is a danger of electric
shock. Especially when you touch the electrode after pushing the measurement
button, 100 V may be applied, which is extremely dangerous.
Warning
・
(Bat) and measurement value blink alternately,
battery life is reached.
If the display blinks or the measured value is not displayed, replace the battery
with a new one and perform measurement again. An accurate measurement
result can not be obtained unless the battery is exhausted and it is below the
rated voltage of this unit.
・
Do not touch the cord / electrode / alligator clip during measurement. The
equipment may be affected and accurate measurement may not be performed.
・
If lateral force is applied to the plug by tensioning the cord strongly, contact
failure will occur. Leave the cord lightly and measure it.
Caution

When you press and hold the measurement switch
(0.5 sec or more), the resistance value is displayed
on the display and measurement starts.
When the object is less than 1 × 10
6
Ω
, the applied
voltage is 10 V, and when the object is 1 × 10
6
Ω
or more, the applied voltage becomes 100 V, one
of the marks will light up.
It turns off automatically after 35 seconds have elapsed.
Since high resistance measurement (10
9
to 10
10
Ω
or more) measures a weak
current, it is susceptible to ambient noise influences, and external factors such as
noise elements may be included in the measurement result.
If highly accurate measurements such as calibration are required, measure after
measures on the next page.
When the resistance value is outside the measurement range,
it is displayed as shown below.
When 9.00 × 10
2
Ω
or less, "9.00 × 10

" indication flashes.
When it is 2.00 × 10
12
Ω
or more, "2.00 × 10

" indication flashes.
The standard stipulates to read the measured value
after 15 seconds. It is also possible to hold the
measured value after 15 seconds according to the
standard (see page 7).
