DC current measurement
1. Connect the black test lead to
and the red test lead to
(for 0–200 mA) or to
(for the range
200 mA – 10 A).
2. Set the multifunction selector to
.
3. Connect the test leads in series with
the current source to be measured.
Read the value.
Warning!
Do not connect the leads in parallel with
the voltage source when measuring current!
If in doubt about the correct range, start with
the highest and work downwards.
When measuring high currents, the meter should only be connected briefly (less than
10 seconds for currents over 5 A). This is to prevent the shunt in the instrument from
overheating.
The interval between two readings must be greater than 15 minutes.
Resistance measurement
1. Connect the black test lead to
and
the red test lead to
.
2. Set the multifunction selector to and
the required range for resistance measurement.
3. Connect the test leads across the circuit to
be tested. Read the value.
Warning:
Ensure that the circuit to be tested is
not “live” before taking any measurements.
In order to avoid the risk of personal injury, never
measure components with a voltage higher than
60 V DC or 30 V AC.
The test leads can add 0.1–0.2 Ω to the actual resistance measured. To obtain accurate
readings of low-resistance components, short-circuit the input sockets beforehand,
record the short-circuited reading and use it to remove the lead resistance error from
the reading on the display.
If the short-circuited reading is higher than 0.5 Ω, check whether any connection/test
lead is loose or damaged.
For high-resistance measurement (>1 MΩ), it is normal for the reading to take several
seconds to stabilize.
For maximum accuracy, leads that are of the highest possible quality and as short as
possible should be used.
