Operation
WARNING: Risk of Electrocution. Before use, always test the detector on a known live circuit to verify proper operation
NOTE on RF Interference: In the voltage mode, RF signals in close proximity to the detector may cause the voltage light and beeper to
latch into a constant tone and light indication. Wait until the RF signal has disappeared before proceeding with voltage detection.

VOLTAGE DETECTION

8. Slide the Function switch to the Voltage position.
9. The "VOLTAGE" LED will light. If the LED is dim or does not light, replace the batteries.
10. Set the Sensitivity adjustment to max.
11. If the detector begins to beep/flash, slowly turn the
12. Touch the detector voltage sensor to the hot conductor
13. If AC voltage is present, the detector light will flash and
14. Adjust the sensitivity as needed to zero-in and identify
CURRENT DETECTION
NOTE: There must be a load on the circuit (current flow) for the current detection function to work.
1.
Slide the Function switch to the Current position.
2.
The "CURRENT" LED will light. If the LED is dim or does not light, replace the batteries.
3.
Set the Sensitivity adjustment to the max
4.
If detector begins to beep/flash, slowly turn the
5.
Move the detector current sensor near the
flashes and beeper sounds.
6.
Slowly reduce the sensitivity and reduce the distance between the sensor and conductor to zero-in and identify the conductor.

BATTERY REPLACEMENT
