• Tests voltage without contact.
• Safety CAT IV 1000 V rated for a wide range of
applications including industrial, commerical,
and residential.
• Water-resistant IP65 rated for indoor and
outdoor use.
• Magnetic solenoid detection to diagnose
electromagnets and relays (NCV-1040-EUR only).
OPERATING INSTRUCTIONS
Turning the Voltage Probe ON
To turn the Voltage Probe on, momentarily press
the ON/OFF button. A continual single ash visually
indicates the Voltage Probe is active in default
voltage range (50 to 1000 V). Press the ON/OFF
button again to switch to high sensitivity
range (12 to 50 V for NCV-1030/1040-EUR only).
A continual double ash indicates the Voltage
Probe’s sensitivity range is at the 12 to 50 V range.
Turning the Voltage Probe OFF
Press and hold the ON/OFF button for longer
than two second to turn the Voltage Probe off. The
absence of ash at the tip indicates the Voltage
Probe is inactive.
Auto Power Off
To save battery life, the NCV-1030/1040-EUR are
enabled with an automatic power off feature. The
Voltage Probe will automatically power off after
approximately 3 minutes of non-use.
Checking for the Presence of AC Voltage
To test for the presence of AC voltage in a
receptacle, insert the tip of the Voltage Probe. To
test a wire, approach the wire with the tip of the
Voltage Probe. Switch between default (50 V to
1000 V AC) and high sensitivity (12 V to 50 V AC)
voltage range detection by short pressing the ON/
OFF button (NCV-1030/1040-EUR only). The LED at
the tip of the Voltage Probe will illuminate and
ash bright red and a buzzer will sound when AC
voltage is detected.
Note: High sensitivity range is optimized for 12 to
50 V range with a maximum indication up to 1000
V. Using the tester above 50 V in high sensitivity
range may affect polarity indication.
When operating the Voltage Probe, always
keep ngers behind the nger guard.
