Operation
Resistance Tests (kΩ)
This is a low voltage (5 V) low current (20 µA)
test for sensitive electronic equipment. It
operates in the same way as the continuity
ranges. This range can be used for diode
testing.
1. Set the selector switch to
kΩ.
2. Connect the test leads.
3. The test will activate automatically.
Voltage Tests (V)
The measured a.c. or d.c. voltage is indicated
on the display. The analogue scale display can
be toggled between the default range of 0 to
500 V (1 V resolution) or the 1 to 50 V (0,1 V
resolution) range by pressing the
TEST button.
When a.c. volts are detected the ----- symbol
will appear next to the '
V'. The presence of
negative d.c. is indicated by '-dc' on the
display, but no reading is given.
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 settle time,the reading will be
displayed automatically.
Live Circuit Warning
When more than 25 V is applied to the
terminals, the instrument defaults to a
voltmeter on all switch positions except
OFF
and Battery Check. In addition, the audible
bleeper will sound on all switch positions
except
OFF and V. All selected tests will be
inhibited except for Insulation tests of 100 V
and above, which will remain available until the
voltage exceeds 55 V.
Note: If the 500 mA fuse has ruptured, the
voltmeter will continue to operate for voltages
greater than 100 V at 50 Hz.
