Chapter 2 Measurement

WARNING
Before taking a measurement, check the position
of the function switch. If the function switch
setting is incorrect, it outputs a voltage for
measuring insulation resistance between
measurement, which may be dangerous.
NOTE
NOTE
2.5 Battery Check
The battery check function places the heaviest
current drain. Check the battery promptly.
1. Remove the probes from the object being
measured. The end of the disconnected may
be short-circuited or open-circuited, but if an
external voltage is applied, an accurate
battery check will not be obtained.
2. Set the function switch to BATT CH.
3. Press the
MEASURE
switch. (The voltage for
measuring insulation resistance is not generated.)
4. If the needle is within the range indication
(battery effective range), the batteries can be
used. If it is to the right of the indication,
replace the batteries with new ones.
Before setting the function switch, if the
MEASURE switch is pressed, the needle may
first swing to the left end of the scale, but it
will indicate an accurate position after about
3 seconds.
