Fluke 1630

The 1630-2 FC clamp measures earth ground loop resistances for multi-grounded systems using the dual-clamp jaw. This test technique eliminates the dangerous and time-consuming activity of disconnecting parallel grounds, as well as the process of finding suitable locations for auxiliary test stakes. You can also perform ground tests in places that were previously difficult: inside buildings, on power pylons or anywhere you don’t have access to soil to place auxiliary test stakes.


Heavy-duty clamp jaw stays in alignment and in calibration even in every day, on-the-job industrial environments.

Logging Measurements

The earth ground clamp saves time by automatically recording data at pre-set intervals and saves up to 32,760 measurements in memory at the set logging interval. Saves time by recording and storing measured values.

Alarm threshold

User-defined high/low alarm limits, for rapid measurement evaluation.

Band-pass filter

Selectable band-pass filter function removes unwanted noise from the ac leakage current measurement.
