"SEL/NCV" BUTTON (FOR SECONDARY FUNCTIONS)

Pushing the "SEL/NCV" Button 12 activates the secondary function for each application accessible by the Function Selector Switch 2. For voltage and current (excluding DC uA), it toggles between AC and DC. For the other functions, it switches between °F and °C, between Hz and % Duty-cycle, and between Continuity, Resistance, Capacitance and Diode-Test. The default function for each application is printed on the meter in white; the secondary function or functions for each setting is printed on the meter in orange.

"SEL/NCV" BUTTON (FOR NCV TESTING)

Press and hold the "SEL/NCV" Button 12 to enter Non-contact Voltage Testing (NCV) mode to test for presence of AC voltage. The NCV icon and "EF" will be present on the display. Approach the conductor under test leading with the sensing antenna 14. In the presence of AC voltage, the red NCV light 13 will flash, audible signals (beeps) will sound, and dashes will appear on the display. As the NCV sensing antenna 14 approaches the voltage source, more dashes will be presented on the display and the frequency of the audible sound will increase. Release the "SEL/NCV" Button 12 to exit NCV testing mode.

NOTE: When NCV Function is initiated, a blinking or steady red glow and an audible beep indicate voltage present and the screen will display the corresponding sensitivity level (1 to 4 bars) when voltage is detected. If no indication, voltage could still be present.

NOTE: Only voltages of 40V AC or greater will be detected.

Press the "HOLD"/Brightness Button ⑨ to hold the measurement on the display. Press again to release the display and return to live measuring.

Press and hold the "HOLD"/Brightness Button 9 to toggle between high and low brightness for the backlight on the main display. By default, the meter will use the low brightness setting on both the main and secondary displays.
