Test equipment earthing components in hard-to-reach places, such as inside buildings or in fully paved areas where you cannot insert an auxiliary grounding pin.
Stay online: determine ground loop resistance without disconnecting and reconnecting the grounding electrode to the system.
The Fluke 1630-2 FC grounding clamp without electrode has the high quality and ruggedness you expect from Fluke.
The heavy-duty clamping jaws remain aligned and calibrated even during daily use in industrial environments.
Electrode-less measurement
The 1630-2 FC clamp measures ground loop resistance for multi-grounding systems using the dual clamp jaw.
This testing technique eliminates the dangerous and time-consuming disconnection of parallel earthing pins and the search for suitable locations to place auxiliary earthing pins.
You can also carry out earthing tests in places that were previously difficult to access: inside buildings, on high-voltage pylons, or anywhere you do not have access to auxiliary earthing pins.
Fluke Connect wireless system
The 1630-2 FC supports the Fluke Connect wireless system (may not be available in all regions).
Fluke Connect wirelessly connects the current clamp to an app on your smartphone or tablet.
The app shows the earth resistance measurements on the display of your smartphone or tablet.
You can store these measurements, your phone's GPS location and images in the Fluke Connect Cloud storage and share them with your team.
Key features
AC ground fault current measurement
Identify AC leakage currents without disconnecting the earth pin from the earthing system, ideal for system fault finding.
Robust
The heavy-duty jaws of the current clamp remain aligned and calibrated, even in daily use in industrial environments.
Recording measurements
The clamp ground tester saves time by automatically recording data at preset intervals and stores up to 32,760 readings in memory at the set recording interval.
Saves time by recording and storing measured values.
Alarm threshold
User-definable high/low alarm thresholds, for quick evaluation of measured values.
Band-pass filter
Selectable band-pass filter function that eliminates unwanted noise from AC leakage current measurement.
