range (0,01kΩ to 10000kΩ) make the resistance
range very useful for general purpose testing.
Voltage Tests (V)
If >1V a.c. or d.c. is present at the terminals the
measured voltage is indicated on the display. The
voltage display will function within specification
even if the fuse has blown.
If the voltmeter operation is in question, test the
voltmeter on a known source.
1. Set the selector switch to V.
2. Connect the test leads.
3. After a short settling time, the reading will be
displayed automatically.
To view the frequency of the a.c. V being measured
press the key. The frequency will be displayed
in the range 16Hz-460Hz. To view a.c. V press the
key again.
Millivolt Tests(mV)
The measured a.c. or d.c. voltage is indicated on
the display.
1. Set the selector switch to mV.
2. Select either a.c. or d.c. mV using the
key.
3. Connect the test leads.
4. After a short settling time, the reading will be
displayed automatically.
Note: Live circuit warning does not function on mV
range.
Zeroing of d.c. mV (no a.c. mV zero facility)
To zero the d.c. mV range, short the leads together
in the d.c. mV position, wait for the reading to
settle and then press the
TEST button. Up to
9,9mV can be zeroed on the d.c. mV range. The
symbol will appear to indicate the zero has
been adjusted.
1. Select the d.c. mV range.
2. Short the test leads together.
3. When the reading has stabilised, press the
TEST button. The zero offset symbol will
appear.
4. To release the zero offset press the TEST
button again.
To view the frequency of the a.c. mV being
measured press the key. The frequency will
be displayed in the range 16Hz-460Hz. To view a.c.
