Designed for extended temperature range use, this digital ground tester is ideally used as an outdoor instrument. Easy-to-use, this ground tester offers the basic functions required for ground system testing, including variable frequency 2, 3, and 4 poles, Attached Rod Technique (ART), ground noise voltage measurement, and more.
Designed for extended temperature range use, this digital ground tester is ideally used as an outdoor instrument. Easy-to-use, this ground tester offers the basic functions required for ground system testing, including variable frequency 2, 3, and 4 poles, Attached Rod Technique (ART), ground noise voltage measurement, and more.
Designed to negate the need for a shorting link when making two-pole measurements, this ground tester also offers labeled auxiliary controls used to select the test frequency (94, 105, 111, and 128 Hz), output voltage (50 or 25 V where local standards apply), and to switch the backlight on or off.
