NCV Function (non-contact voltage detection)
The NCV function (Non-Contact-Voltage detection) allows voltage in lines to be
detected without contact occurring. The NCV sensor is situated at the tip of the cur-
rent sensor.
Bring the NCV sensor close to a line or cable. The red diode is lit when voltage is
present (2). This function is also active when the meter is switched off.
☞
The highly sensitive NCV sensor may cause the diode to glow when
static electricity is present. This is normal and not a malfunction.
Always test the NCV function on a known voltage source in order to
avoid incorrect detection. Incorrect detection creates the risk of elec-
tric shock!
Auto power OFF function
The meter turns off automatically after 30 minutes if no button or switch is operated.
This function saves battery power and extends the service life.
To restart the meter after an automatic shutdown, touch the rotary switch.
