The PRS-812 is a comprehensive range of portable constant voltage resistor instruments designed for dedicated ESD auditors and professionals. The PRS-812 is a cost-effective choice for ESD professionals who require excellent accuracy and performance without data downloading. Like its big brother, the PRS-801, the PRS-812 offers an excellent combination of performance, including measurement speed, wide range and accuracy. Its constant test voltage system is extremely stable and consistent with laboratory-grade benchtop instruments.

Measuring range

The PRS-812’s accurate wide range is 0.1 to 9.9×10*12 ohms, providing better flexibility for measurement applications. In fact, it’s three in one because what it does is:

Low resistance range instrument for measuring 0.1 to 1.0×10*4 ohms. Most competitive instruments cannot measure accurately at or below 1.0×10*3 ohms. Therefore, a typical ESD practitioner must carry a DMM to perform low-resistance checks of ground connections. To ensure accuracy in the field, the PRS-800CC calibration shunt is used to confirm and adjust accuracy over its 0.1 to 10 ohm resistance range.

A wide range of audit tools that meet and exceed ANSI/ESD S20.20 and TR53 periodic verification (audit) program requirements, ranging from 1.0×10*3 to 1.0×10*11 ohms. The measurement guidance requires measurement of the resistance requirements of the ESD program for facilities ranging from less than ten years to more than ten years. Depending on program requirements, the PRS-812 can easily exceed this requirement by up to 2 decades.

Precision high-resistance instruments for packaging measurement, material and product testing, and acceptance verification to S541 standards. Few competing instruments are better at measuring up to or beyond 1.0×10*11 ohms, while the PRS-812 can easily measure up to 1.0×10*12 ohms.

Measurement flexibility

Connects to virtually any 2-wire fixture or electrode configuration.

The PRS-812’s simple ¾-inch terminal spacing provides connections to a variety of electrodes and fixtures.

Terminal design allows use of mechanically shielded or unshielded banana plug leads

BNC adapter with ¾-inch spacing mounts directly to PRS-812 terminals for measurements with a wide range of probes and fixtures

Measurement speed: power-on period

Along with the PRS-801, the PRS-812 is one of the fastest measuring instruments on the precision measurement market today. Laboratory testing confirms that the PRS-812 can measure 0 to 1.0×10*12 ohms in 2.5 seconds. Therefore, the electrification time (EP) is 8 seconds based on the surface resistance of ANSI/ESD STM11.11 planar materials. Additionally, its EP automatically adjusts to ensure stable measurements are displayed.
