1. Touch the one of the socket pin with the tip of the sodium lamp test
antenna.
2. Press and hold down the LAMP TEST button
• The bulbs is good if glowing.
• If the bulb does not glow, repeat lamp test with touching the other
socket pin.
Note: If the bulb glows with either of socket pins during lamp test, the
lamp is good. In some cases, only part of the bulb will glow, the other part
should glow when testing the other socket pin.
VolTect™ Non-contact Voltage Detection
Amprobe LT-10 Lamp Tester is NOT equipped with a probe tip to be inserted
into the slot of the receptacle contact. Testing voltage that way will not be
reliable.
The LT-10 can only be used for detecting hot wires in outlets when the
wiring is exposed.
With some cables, such as extension cords, hot and neutral wires might be
twisted. In order to reliably test voltage, move the tester along the cable for
some distance (typically a few inches). The tester will only indicate voltage
in places where the hot wire of the twisted wires is closer to the tester. It
will NOT indicate voltage in other places of the cable.

WARNING!
• To avoid electric shock, do not touch ANY part of antenna during lamp
or voltage tests. Touching antenna during these tests affects tester
sensitivity.
• If the instrument is used in a manner not specified by the manufacturer,
protection provided by the tester may be impaired.
• Test on a known energized source within the rated ac voltage range of
the instrument both before and after use to ensure the instrument is in
good working condition.
• The non-contact voltage detection function is always on. When the
probe or antenna is close to energized wires, LED flashes and beeps.
Non-contact voltage detection will be disabled when the LAMP TEST
button is pressed.
