Have confidence in your measurements
The PRS-801B Resistance System provides the resolution and accuracy to efficiently measure resistance point-to-point (Rtt) and resistance-to-ground (Rtg) of floors, worksurfaces, carts, garments, packaging, planar material in accordance with all of the ESD Association documents for resistance measurements, such as ESD TR53, ANSI/ESD S4.1, ANSI/ESD S7.1, ANSI/ESD STM97.1, ANSI/STM S11.11, ANSI/STM S11.12 and ANSI/STM S11.13.

The ideal tool for product qualification
The PRS-801B digital resistance meter has an outstanding performance combination of measurement speed, wide range and accuracy. Its constant test voltage system is extremely stable and consistent with lab level, bench top instruments.

The widest range meter
The PRS-801B’s wide range offers the maximum flexibility in measurement applications. The PRS-801B is the only battery operated meter with a range of 0.01 ? to 2.00x1014 ?. In fact, the PRS-801B serves as 3 instruments in 1:

A low resistance range meter for measurements from 0.01 to 1.0x104 ?. Most portable instruments do not measure accurately at or below 1.0x103 ohms. Therefore, a typical ESD Auditor must carry a digital multimeter for low resistance checks of ground connections.
A wide resistance range audit meter to meet ANSI/ESD S20.20 and TR53 procedures from 1.00x103 to 1.00x1011 ?. Measurement guidelines require accurate measurements from one decade below to one decade above the resistance requirements of a facility’s ESD program. The PRS-801B easily exceeds this requirement by as much as 3 decades, depending on program requirements.
Precision high resistance measurement instrument for Packaging to S541 Standards, material and product testing and acceptance verification.
Few competitive instruments can measure accurately up to or beyond 1.00x1011 ohms, while the PRS-801B comfortably measures up to 2.00x1014 ohms.

There are no audit instruments or laboratory bench top instruments that perform in the PRS-801’s wide range

Designed to be more productive and work more efficiently

Easily toggle between exponential and ohmic measurements on the display
Internal memory capable of storing and recalling up to 999 data sets
Programmable color LED’s indicating resistance ranges
Easy-access door for fast battery changes without breaking the calibration seal
Battery status indicator on the display

Measurement flexibility
Connect to virtually any 2-wire fixture or electrode configuration. The PRS-801B’s simple ? inch terminal spacing provides connectivity to a variety of electrodes and fixtures.

Terminal design allows use of mechanically shielded or non-shielded banana plug leads
BNC adapters with ? inch spacing mount directly to the PRS-801B terminals for measurements with wide range probes and fixtures
An instrument reference allows use of a third wire instrument reference to minimize effects of extraneous fields on precision fixture measurements
Electrification period
The PRS-801B is one of the fastest measurement instruments in today’s precision measurement market. Laboratory tests confirm the PRS-801B can measure from 0 to 1.0x1012 ohms in 2.5 seconds. Thus, its specified electrification period (EP) is 15 seconds in accordance with ANSI/ESD STM 11.11 Surface Resistance of Planar Materials. Furthermore, its EP is automatically adjusted to insure a stable measurement is displayed.

Multiple modes of operation
The PRS-801B has Automatic, Manual, Auto-Manual and Continuous operational modes, plus exponential display or standard numeric display in ?, K?, M?, G? and T?. It’s easy to use and read. Measurements are summarized in decades using multiple LED’s from <103 to >1014, whose colors are user programmable to be RED, GREEN or YELLOW.

Constant test voltages
PRS-801B has three Test Voltages ranges that provide stable test references for repeatable measurements. In AUTO mode, the instrument automatically selects the proper test voltage for the resistance being measured.
