Operating instructions
Warning!
• Before measuring voltage, always ensure that the meter is set to the correct
function range and not set to current, resistance or diode test measurement.
Always ensure that you use the correct test lead socket for the type of
measurement to be made.
• Use extreme caution when measuring voltages over 60 V, especially when
the circuit being measured has a high power output.
• Make sure that the circuit to be measured is not “live”, i.e. conducting any current,
before connecting test leads in series with it (such as when measuring current).
• Make sure that the circuit to be tested is not conducting any current before
performing resistance measurements or diode tests.
• Always ensure that the correct function and range are selected. If in doubt about
the correct range, start with the highest and work downwards.
• Take extreme care when using the meter on an inductive component such
as a transformer, relay coils and the like. High voltage may be induced at
the measuring points if an open circuit occurs.
• Make sure that the test leads are in good condition with no damage to the insulation.
• If you replace the fuse, make sure that it is the correct type and rating.
Voltage measurement
Check the battery by rotating the multifunction selector to a new measuring function.
The battery symbol will appear if the battery starts to run low.
1. Connect the black test lead to
and
the red test lead to
.
2. Set the function selector to
(200/250 V~) or
(200 mV – 250 V)
and the required measuring range for
voltage measurement.
3. Connect the test leads across the voltage
source to be measured. Read the value.
Note:
If the incorrect polarity is connected
when measuring DC voltages, the display will
show
(minus) before the reading.
Note:
In each range, the meter has an input impedance of 10 MΩ except the mV range,
which has an input impedance of 3000 MΩ. This can cause measurement errors in
high impedance circuits. If the circuit impedance is less than or equal to 10 kΩ,
the error is negligible (0.1 % or less).
