2. Introduction
The VP5x-2 detects the presence of AC voltage at electrical outlets, junction strips, electrical circuits, and other devices without having to contact the device physically. The VP50-2 (110 V regions) has a minimum excitation voltage of 90 V AC (this is its normal, or low sensitivity, mode); The VP52-2 (220 V regions) has a minimum excitation voltage of 190 V AC (this is its normal, or low sensitivity, mode). Both models have a high sensitivity mode allowing detection down to 24 V AC. Tactile vibration, audible beeper, and visual cues alert the user when AC voltage is present.

4. Safety
NOTE
This device will not detect DC voltage.
Before and after each use, verify proper operation by testing on a known ‘live’ circuit (withinthe stated range of this device).
Static electricity can randomly trigger this device, this is normal for a device of this type.
In bright light conditions, the indicators will be less visible.
WARNING
Please read, understand and follow all warnings, cautions, safety information and instructions before operating this device. Failure to do so can result in death or seriousinjury.
Keep hands and fingers on the body of the probe when measuring, do not touch livecircuits.
Risk of electric shock and burn. Contact with live circuits could result in death or seriousinjury.
This device may not detect voltage if: The user is not holding the tester, the device is attoo long a distance from the voltage source, or if the tested frequency is outside of thespecified range.
Do not attempt to detect voltages outside the specified range.
CAUTION
Use caution with voltages > 30 V AC.
If the device indicates that no voltage is present, voltage may still be present, use cautionand double check your test results.
Never assume neutral or ground wires are de-energized. Neutrals in multi-wire branchcircuits may be energized when disconnected and must be retested before handling.
Voltage detection performance is affected by varying electrical socket designs and insulationthickness/type; use caution.
Do not use this device if it is wet, does not power up properly, appears damaged, or ifdoes not function properly.
Always wear protective clothing and eye-ware.
Do not use this device for purposes that have not been outlined in the user documentation.
Do not attempt to repair this device. There are no user-serviceable parts.
Do not expose this device to extremes in temperature or humidity.

6. Operation
WARNINGDo not use this instrument before testing on a known live circuit.
WARNINGKeep hands and fingers on the probe body, away from the probe tip.
6.1 Low (normal) and High Sensitivity ModesThe 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 button (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.
CAUTIONStatic 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
Short press the power button (5) to switch the meter ON. The meter vibrates briefly, beeps twice, and the tip lights (2) turn ON.
When ON, the status indicator (4) should be solid green, indicating a proper working condition.• If the status indicator is flashing amber, replace the batteries.• If the status indicator is flashing red, the meter is malfunctioning (contact FLIR for Service).
Once powered, short press the power button to toggle the sensitivity modes. The beeper will sound when the sensitivity is changed. See the Low and High Sensitivity Modes section for additional information.WARNINGTest on a known live circuit before testing on an uncertain circuit. Varying electrical socket designs and insulation thickness/types can affect voltage detection performance.
Hold the AC voltage sensor (1) very close to the voltage source.
If voltage is present, the meter vibrates, beeps, and the alarm indicator (3) flashes.• With voltage detected, in the normal (low sensitivity) mode, the alarm indicator flashes red.• With voltage detected, in high sensitivity mode, the alarm indicator flashes amber.
To switch OFF, long press the power button. The meter beeps once and the status indicator and tip lights switch off.
6.3 FlashlightTo turn the flashlight (9) on or off, long press the flashlight button (7), the meter will beep. Note that the voltage detector does not operate while the flashlight is ON.
6.4 Low Battery IndicationThe status indicator (4) flashes amber when the batteries need replacing. After 1 minute of flashing, the meter automatically switches OFF. See the Maintenance section for battery replacement instructions.
6.5 Auto Power OFF (APO)The meter switches OFF after 3 minutes of inactivity. The flashlight switches OFF after 30 minutes, regardless of activity.
7. Maintenance
7.1 Cleaning and StorageWith the meter OFF, clean with a damp cloth and mild detergent, do not use harsh detergents, abrasives or solvents.
Use compressed air to clear dust from the flashlight lens. Clean the lens with a commercial lens cleaner if necessary.
Ensure that the device is dry before performing tests. When storing for long periods, remove the batteries and store separately.
7.2 Battery Replacement
Switch the meter OFF before replacing the batteries.
Unscrew the cap, as shown.
Replace the 2 x ‘AAA’ batteries, observing correct polarity, as shown on the outside of the case, near the compartment cap.
Secure the cap, ensuring that the red plastic ring in the battery cap aligns with the battery, as shown.
Check that the device powers up correctly before attempting to make measurements.
Recycle used batteries; do not dispose in household trash. Follow all regulations with respect to the disposing of this device at the end of its lifecycle.
