For electrical applications the test leads can be connected to Live (B), Neutral (A) and Earth (E) and the voltages measured and stored
without having to disconnect the test leads from the three conductors.
Test probes and crocodile clips are supplied for connection to the circuit under test.
Fused test leads are available as an optional accessory.
7.4 SP5 Switched probe (not MIT400/2, MIT405/2 )
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 as below:
1. Connect the SP5 probe to the instrument using the special 3-pole +ve socket ( this replaces the RED test lead).
2. Select a suitable insulation resistance range.
3. Press and hold down the SP5 probe button. The instrument will start an insulation resistance test.
4. To end the test, release the probe test button.
