OPERATING INSTRUCTIONS:
Modes of operation:
The NCVT-2 can operate as a dual range (NCVT-2 mode) or single range (NCVT-1 mode) tester. In
NCVT-2 mode, the tester will light a steady blue LED in the tip to indicate power-on and dual range
mode. In NCVT-1 mode, the tester will light a steady green LED in the tip to indicate power-on and
single range mode.
Turn unit on:
Press and hold the power button for ½ second, then release. Listen for single-beep sound and
watch for a steady green or blue LED to illuminate in the tip of the tester. The tester is now
activated and is operational. Test on known live circuit to verify tester functionality. See Silent
mode for additional power-on options.
Turn unit off:
Press and hold the power button for ½ second then release. Listen for a double-beep sound and
watch the green or blue LED turn off. The tester is now deactivated and is not operational.
System self-test:
The "power on" blue or green LED visually confirms battery sufficiency, system integrity, and
operation/active mode. Always test on known live circuit to verify tester functionality prior to use.
Changing operation modes:
While the unit is powered on, press and hold the power button for 2 seconds. The power-on LED
will switch from blue to green or green to blue. The tester will start in whichever mode it was last
powered off in.
Checking for the presence of AC voltage:
Prior to use, test on known live circuit to verify tester functionality. Place tip of the tester near an
AC voltage and refer to the tables below for each mode:
NCVT-2 mode:
POWER-ON
Audible
Single Beep
Visual
Steady Blue LED Blue LED Turns OFF and Red LED
NCVT-1 mode:
POWER-ON
Audible Single Beep
Visual
Steady Green LED Steady Green LED
In NCVT-2 mode, the tester will be more sensitive and will show voltage indication at a further
distance away from a high voltage source than in NCVT-1 mode. Use NCVT-1 mode in situations
where you expect the voltage source will be greater than 48V AC.
Low battery indication:
Scenario 1 – Powering on the tester: The "power on" LED in the tip of the tester changes from a
steady green or blue to a blinking green or blue and a series of beeping sounds is generated. The
tester then turns off. The unit is now deactivated and is not operational, the batteries require replace-
ment. To replace the tester batteries refer to the Maintenance section titled "Battery Replacement."
Scenario 2 – Operating the tester: If the LED lights dim and the tone fades, the tester may require new
batteries. To replace the tester batteries refer to the Maintenance section titled "Battery Replacement."
Auto Power Off:
After 4 minutes of non-use, the tester automatically powers off to conserve battery life. Listen for
a double-beep sound and watch the "power on" LED turn off. The tester is now deactivated and
is not operational.
Silent mode:
The tester can be operated with only visual indication of voltage. With the tester powered off, press
and hold the power button for 2 seconds then release.
MAINTENANCE:
Battery Replacement:
• Orient the tool/tester with the pocket-clip facing you.
• Gently depress the tab, Fig. 2, until you can slide the end-cap off the main body of the tester.
• Remove the batteries using caution to prevent damage or injury to the internal components.
• Replace with two 1.5V AAA or LR03 or NEDA 24A batteries.
• Place batteries into tester with the positive terminals facing the tip, Fig. 3.
• Carefully align and slide the end-cap to the body of the tester, Fig. 4. Push the cap until it is
fully seated (denoted by a clicking sound), Fig. 4.
• Note: Hold pocket-clip on cap close to tester body while sliding cap onto tester.
• Test on known live circuit to verify tester functionality.
