5.2. Preliminary Note
1.
To check the 9 V battery please switch on the DMM. If the
battery is weak, a "LO BAT" or "BAT" sign will appear on the
left of Display. If this does not appear on the display proceed
as below. See "Maintenance" if the battery has to be replaced.
2.
The warning sign next to the test leads jack is for warning that
the input voltage or current should not exceed the indicated
values. This is to prevent damage to the internal circuitry.
3.
The function switch should be set to the range which you want
to test before operation.
5.3. DC Voltage Measurement
1.
Connect the black test lead to the COM jack and the red test
lead to the V/
Ω
/ mA- jack.
2.
Set the function switch to the DC V range to be used and
connect the test leads across the source or load under
measurement.
Note:
1.
If the voltage range is not known beforehand set the function
switch to the highest range and work down.
2.
When only the figure "1" is displayed, overrange is being
indicated and the Function switch must be set to a higher
range.
3.
CAUTION
: Do not apply more than 600 V to the input.
Indication is possible at higher voltages but there is danger of
damaging the internal circuitry.
4.
Use extreme caution to avoid contact with high tension circuits
when measuring high voltage.
