2.5. NON-CONTACT VOLTAGE DETECTION
(NCV)
The instrument can detect an AC voltage of approximately
230V.
„ Withdraw the probe tips.
„ Set the switch to NCV.
„ Move the top of the instrument (+ terminal side) close to the
conductor without touching it. The position of the instrument
may affect the result. The sensitivity is better on the battery
compartment cap side (Figure 15).
If no alternating voltage is detected, the device displays EF.
If a voltage is detected, the device displays one of 4 detec-
tion levels:
„ -
, the buzzer beeps once a second and the backlighting
flashes at the same rate.
„ - - , the buzzer beeps twice a second and the backlighting
flashes at the same rate.
„ - - - , the buzzer beeps three times a second and the
backlighting flashes at the same rate.
„ - - - -, the buzzer emits a continuous beep and the back-
lighting is on continuously.
The absence of a voltage indication in the NCV func-
tion does not mean that there is no voltage. To confirm
the absence of a voltage, use a VAT.
2.6. AUTOMATIC STANDBY
To save the batteries, the instrument automatically switches to
standby after 10 minutes without user activity (switch turned
or Select key pressed).
The instrument can be reactivated by turning the switch or
pressing the Select key.
