Non Contact Voltage Detection (Ncv) - Metrix MTX204 Bedienungsanleitung

long and exceed 15s.

3.10. Non Contact Voltage Detection (NCV)

The NCV mode detects only AC voltages connected to the network with
respect to ground. Always check for the presence of a voltage with a voltage
measurement. To measure the absence of a voltage, use a VAT

Network : 230V only, 50 Hz (sensitivity : 10 mV)
The meter can detect AC live voltage without contact.
The NCV detection zone is displayed on the sheath.
1. Remove all test leads from the Meter
2. Turn the rotary switch to
3. Approach live conductor from LCD (position
of the Meter may affect measurement)

If no AC live voltage is detected the Meter will
display EF and product will be silent.

If AC live voltage is detected product will show 4
different levels:
from - to ----, at – buzzer will sound discontinuously,

at ---- buzzer will sound continuously, and backlight will
blink red. Basic detection voltage is for 220/230V.

NCV is only for indication purpose and shouldn't be
used for measurement, or to detect the absence of
voltage.
The NCV mode has an indicative meaning only and must not be used either for
measuring nor detect the absence of voltage.
An engraved marking on the sheath indicates the position of the antenna for NCV
indication.
