The Fluke 1630 is a MUST HAVE for those who are intent on improving the reliability of their systems and making it impervious to impulse damage. The Fluke 1630 is easy to use, highly accurate and an industry standard”- verified purchaser

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.

Earth ground ac leakage current measurement
- Identify ac leakage currents without disconnecting the earth ground stake from the grounding system–ideal for system troubleshooting.
- Rugged 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
- 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.

Fluke Connect® Wireless System
- The 1630-2 FC supports the Fluke Connect Wireless System connects the clamp with an app on your smartphone or tablet (may - not be available in all regions).
- You can save these measurements, and images to Fluke Connect Cloud storage and share with your team.
- Maximize uptime and make confident maintenance decisions with data you can trust and trace.
- Access baseline, historical and current measurements by asset.
- Share your measurement data using ShareLive™ video calls and emails.
- The 1630-2 FC is part of a growing system of connected test tools and equipment maintenance software. Visit the website to learn more about the Fluke Connect system.

The P3100 models are available in single or dual piston format. Unit can be supplied in psi, bar, kgf/cm², and MPa. This robust instrument is highly accurate, quick and easy to use. Units feature a built-in priming pump for large volume applications, piston flotation indicators and a high quality screw press for fine pressure control.
Operating principle
Deadweight testers are the high performance pressure standards for pressure measurement. Utilizing the well proven piston-gauge system consisting of a vertically mounted, precision lapped piston and cylinder assembly, accurately calibrated weight masses (Force) are loaded on the piston (Area), which rises freely within its cylinder. These weights balance the upward force created by the pressure within the system. The pressure is measured when placed on a correctly spinning and floating piston. The total pressure measured is the summation of the weights plus the piston weight carrier assembly.
Instrument base
There are three basic variations in the hydraulic offering; single low pressure, single high pressure and dual piston models. Pressure is generated and controlled by means of a high quality screw press located on the front of the tester. A built-in hand pump is included as standard for all hydraulic models to prime the system and accommodate large volume requirements.
Piston/cylinder assemblies
The piston/cylinder assembly is the heart of each deadweight tester. They are manufactured from materials that provide stability, durability, and low thermal coefficients and distortion. Our experience and knowledge of piston/cylinder production and calibration ensure the precision and performance required for today’s demanding calibration requirements.
Weight masses
Standard weight masses are series 3 nonmagnetic austenitic stainless steel. Each mass is marked with the serial number of the instrument and the nominal pressure value relative to the high or low-pressure piston, when applicable. Optional fractional weights are stainless steel and/or solution heat treated aluminum.
Gravity correction
Gravity varies significantly with geographical location and this variation has a direct effect on the force of the weights and the accuracy of the deadweight tester. Each instrument can be calibrated to local gravity at no extra cost. If unspecified, instruments will be calibrated to Standard Gravity at 980.665 cm/s2.
