The Fluke 1555 insulation resistance tester offers digital insulation testing up to 10 kV, making it ideal for testing high voltage equipment including switchgear, motors, generators and cables.
Data collection is easy using the Fluke Connect® wireless app. Remote operation lets you spend as little time as possible in potentially hazardous zones. Real-time trending shows a live graph on your phone, rather than a hard-to-read set of changing values. And you can create reports quickly, using pre-designed templates that you can customize with company logos. The 1555 insulation tester can now conduct the entire range of test voltages specified in IEEE 43-2000 with a best in class, 3 year warranty and CAT IV 600 V safety rating.
Other useful features:
• Automatic calculation of Dielectric Absorption (DAR) and Polarization Index (PI) with no additional setup
• Guard system eliminates the effect of surface leakage current on high-resistance measurements
• Selectable test voltages in 50 V steps from 250 V to 1000 V, and 100 V steps above 1000 V
• CAT III 1000 V, CAT IV 600 V safety rating
• Warning function alerts the user that line voltage is present and gives the voltage reading up to 600 V AC or DC for increased user safety
• Measurements can be stored in up to 99 memory locations, with each location assigned a unique, user defined, label for easy recall
• Long battery life gives the user over 750 tests between charges
• Large digital/analog LCD for easy viewing
• Capacitance and leakage current measurement
• Ramp function for breakdown testing
• Resistance measurements up to 2 TΩ
• Timer settings up to 99 minutes for timed tests
• 3-year warranty

Key Features
• Quickly configure, start and stop tests on the 1555 remotely, a safe distance away from any operating, energized equipment, using Fluke Connect® and a smart phone
• Real time trending gives you easy-to-see visual cues, rather than hard to read, rapidly changing values
• Report creation using Fluke Connect desktop saves time and makes test results easier to understand
• Fluke Connect saves test results to the cloud for analysis and preventive maintenance

The P3200 models are available in single or dual piston formats for increased operating ranges. Units 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.

PressCal software for pressure calculations and certificate generation
Operating principle
Deadweight testers are the high performance pressure standard 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.
