COM: Terminal receiving the black test lead as common
reference.
μAmA: Terminal receiving the red test lead for μA and mA
measurements.
10A: Terminal receiving the red test lead for 10 A measurements.
7. Operating Instructions
Risk of electric shock during operation. Be very careful when
measuring live circuits.
To avoid damage, the meter features an alarm function. Check the
connections, the range, and the terminals as soon as the meter
buzzes.
However, this is only an indication and does not provide protection
against damage or misuse!
Never exceed the limit value for protection. This limit value is listed
separately in the specifications for each range of measurement.
Do not touch unused terminals when the meter is linked to a circuit that is
being tested.
Only use the meter in the indicated overvoltage/installation category.
Never measure voltages that might exceed the indicated category values.
Disconnect the test leads from the tested circuit before rotating the range
selector in order to change functions.
When carrying out measurements on a TV set or switching power circuits,
always remember that high amplitude voltage pulses at the test points
might damage the meter.
Always be careful when working with voltages above 60 Vdc or 30 Vac rms.
Keep your fingers behind the probe barriers at all times during
measurements.
Do not measure current in circuits with voltages > 250 V.
Never perform resistance, diode, or continuity measurements on live
circuits. Make sure all capacitors in the circuit are depleted.
Non-Contact AC Voltage Detector
Remove the test probes when performing non-contact voltage
measurements.
This function only provides a quick indication whether AC
voltages are present. It is not a fully reliable way to determine
whether a circuit is safe to touch without risk of electrical shocks.
1. Set the rotary switch to the EF-
2. Place the top of the meter as close as possible to the lead or the mains
outlet. The green LED turns red and the meter beeps if an AC voltage is
present.
Note: This function is only an indication whether an AC voltage is present,
and does not guarantee that a circuit is voltage-free. It does not detect DC
voltages. If in doubt, perform a full voltage measurement.
