• UL Certified CAT IV 600V AC, 24 to 600 V AC
• An LED Flashlight in the tip operates independently of the tester functions and can be used to illuminate the work area. Press the Flashlight Button to turn it On/Off. The tester is set to Flashlight Off. The Flashlight will Auto Power Off after 5 minutes.
• Audible Notification Disable - The tester can be operated with a visual only indication of voltage when working in noise sensitive/noise restricted area with the simple press of a speaker button.
• Auto Power Off - After 10 minutes of inactivity (no button pressed and no signals detected), the tester will emit one long beep (~0.5s) and then shut off. Note: if the flashlight is on, it will be also shut off.

The IDEAL 61-637 is CAT IV 600 V AC, UL Listed, Single Range Non-Contact Voltage Tester that automatically detects and indicates the presence of voltage within range of range of 24 - 600V AC . The tester provides non-contact detection of voltage through an antenna enclosed in plastic at the tip of the tester which senses the presence of the electromagnetic field present around live conductors. The tip is illuminated by a green LED when powered on and switches to a red flashing LED, and audible beep that increase in frequency as the voltage level increases. The tester is powered by two 1.5V AAA batteries and features an in tip LED flash light, an audible disable function, a lanyard tie-off point, an auto power off function and a low battery indication.

The tester can be operated with a visual only indication of voltage when working in noise sensitive/noise restricted areas. With the tester On, press the Speaker button for less than 1s. The tester will beep once to indicate the audible warning is muted and only a visual indication will be provided. To restore the audible warning, press the speaker button for less than 1s. The tester will beep twice to indicate the audible warning is active and both a visual and audible indication will be provided. The tester is set to Audible Notification On as the default setting.

An LED Flashlight in the tip operates independently of the tester functions and can be used to illuminate the work area. Press the Flashlight Button to turn it On/Off. The tester is set to Flashlight Off. The Flashlight will Auto Power Off after 5 minutes of no voltage detection. Further voltage detection will reset the APO function to 5 minutes again.
