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.
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 triangle, replace the batteries. If the sta-
tus indicator is flashing red, the meter is experiencing a malfunction—
contact FLIR Systems for service.
