Non-Contact AC Voltage Measurements

Risk of Electrocution. Before use, always test the voltage de-
tector on a known live circuit to verify proper operation.
In order to realise the test it is necessary to realise the following
actions:

touch the current clamp to the live conductor or insert into the
live side of the electrical outlet,

if AC voltage is present, the detector light will illuminate.
The conductors in electrical cord sets are often twisted. For
best results, rub the probe tip along a length of the cord to
assure placing the tip in close proximity to the live conduc-
tor.
The detector is designed with high sensitivity. Static electric-
ity or other sources of energy may randomly trip the sensor.
This is normal operation.

Manual range selection

When the meter is first turned on, it automatically goes into Au-
toRanging. This automatically selects the best range for the meas-
urements being made and is generally the best mode for most
measurements. For measurement situations requiring that a range
be manually selected, perform the following:
