WARNING
Do not use the unit if it is wet or if there is damage to it. Injury to persons can
occur.
WARNING
Do not apply more than the rated voltage between the probe tip and the
ground. This can cause damage to the instrument and injury to persons.
WARNING
Do not operate with the case open. Injury to persons can occur.
5.1 Modes
The meter operates in two different modes: Normal mode and High-sensitivity
mode. The excitation voltage required to activate the meter alarm is much lower
in High-sensitivity mode.
• In Normal mode, the minimum excitation voltage is 90 V AC (FLIR VP50)/190
V AC (FLIR VP52).
• In High-sensitivity mode, the minimum excitation voltage is 24 V AC.
Note
Static electricity and other stray sources of energy can randomly trigger the
FLIR VP50/VP52 sensor. This is normal. Random triggering is more likely in
high sensitivity mode but certainly can occur in the normal sensitivity mode as
well.
5.2 Basic operation
1. Press and hold the power button for at least 2 seconds to switch on the me-
ter. The meter vibrates briefly and the tip light turns on. The status indicator
should be solid green, indicating a proper working condition. If the status in-
dicator is flashing amber through the square, replace the batteries. If the sta-
tus indicator is flashing red, the meter is experiencing a malfunction—
contact FLIR Systems for service.
