In continuity mode, if a voltage greater than 25 V exists, testing
will be automatically inhibited and voltage measurement will be
displayed.
SP5 Switched probe
The SP5 switch probe allows the user to start a test by pressing the
[TEST] button on the probe, instead of on the instrument. This
allows for complete hands-free testing and increases user safety.
AC/DC voltage and frequency measurements
Note: Measured voltage must not exceed 600 V phase to earth or
Phase to Phase.
Note on TRMS measurement:
IN TRMS mode the instrument will measure both AC and DC
components of the supply voltage (AC+DC). In DC mode only the
DC component is measured.
1. Rotate selector switch to the ‘V’ position.
2. Connect test leads to the circuit under test.
3. Press the [TRMS] button to select DC or return to TRMS.
4. The measured voltage will be displayed on the main digital scale
in units of V or mV, as appropriate In TRMS mode, the measured
frequency (Hz) will be simultaneously displayed.
Insulation resistance testing - general
Safety note:
Insulation resistance testing is performed at high DC voltages and is
hazardous if touched. Always observe the safety precautions when
