Multimeter Features
Detecting AC Voltage Presence (Vsense) (U1242C only)
The Vsense detector is a non-contact voltage detector that detects the presence
of AC voltages nearby.
– You are advised to test on a known live circuit within the rated AC voltage
WARNING
– Voltage could still be present even if there is no Vsense alert indication.
– The Vsense detector may be affected by differences in socket design,
You are advised to measure voltage by using test leads through the Z
