WARNING
Do not use this instrument before testing on a known live circuit.
WARNING
Keep hands and fingers on the probe body, away from the probe tip.
6.1 Low (normal) and High Sensitivity Modes
The meter operates in one of two modes: normal (low sensitivity), mode, or
high sensitivity mode. The excitation voltage required to activate the meter
alarm is much lower in the high sensitivity mode, see below.
• In Normal (low sensitivity) mode, the minimum excitation voltage is 90 V
AC (VP50–2) or 190 V AC (VP52–2).
• In high sensitivity mode, the minimum excitation voltage is 24 V AC.
• Toggle the low and high sensitivity modes by short pressing the power but-
ton (with the unit powered up).
• In normal (low sensitivity) mode, the status indicator illuminates solid green.
• In high sensitivity mode, the status indicator illuminates solid amber.
• The VP50–2 is intended for 110 V AC regions and the VP52–2 is intended
for 220 V AC regions.
CAUTION
Static electricity and other stray sources of energy can randomly trigger the sensor, this is
normal. Random triggering is more likely in high sensitivity mode but can also occur in the
low sensitivity mode.
6.2 Basic Operation
1. Short press the power button (5) to switch the meter ON. The meter vi-
brates briefly, beeps twice, and the tip lights (2) turn ON.
2. When ON, the status indicator (4) should be solid green, indicating a prop-
er working condition.
• If the status indicator is flashing amber, replace the batteries.
• If the status indicator is flashing red, the meter is malfunctioning (con-
tact FLIR for Service).
