BUTTON OPERATION

Non-Contact Voltage Detection key, is used to detect power with a sensor located at the
tip of the clamp head and indicates positive response with an audible alarm and visual LED
indicator light just above the "NCV" button. See reverse side for instructions.
Selection key, switches measurement functions that share a selector position. By pressing
"SEL" key to toggle between AC and DC Volts, Diode, Continuity, Capacitance and Resistance.
Range key, press "RAN" key; to toggle between Automatic Ranging and Manual Ranging.
"Auto" icon will show on the display. Press and hold "RAN" to return to Auto Ranging.
Frequency / Duty Ratio selection key. Pressing this key can select Voltage / Frequency / Duty
Hz%
Ratio or Current / Frequency / Duty Ratio pending selector position.
Hold key, press "HOLD" key; the reading will be locked and "HOLD" icon will display on
display. Press "HOLD" key again to release.
Backlight key: Press and hold "Backlight" key for 2 seconds to turn on. Press and Hold again
