Wide Range. Accurate. Portable

The widest range portable constant voltage resistance instrument in today's market, the PRS-801 is the choice of most ESD professionals. Why? Because the PRS-801 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.

Measurement Range

The PRS-801's wide range offers the maximum flexibility in measurement applications. In effect, it is 3 instruments in one because it functions as:

  • A low resistance range instrument for measurements from 0.1 to 1.0x104 ohms. Most competitive instruments do not measure accurately at or below 1.0x103 ohms. Thus, the typical ESD practitioner must carry a DMM for low resistance checks of ground connections. To ensure-field accuracy, the PRS-801CC Calibration Shunt is used to confirm and adjust the accuracy of its 0.1 to 10 ohm resistance range.
  • Wide range audit instrument to meet ANSI/ESD S20.20 and TR53 procedures from 1.0x103 to 1.0x1011 ohms. Measurement guidelines require accurate measurements from one decade below to one decade above the resistance requirements of a facility's ESD program. The PRS-801 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 1.0x1011 ohms, while the PRS-801 comfortably measures up to 2.0x1014 ohms. There are no audit instruments or laboratory bench top instruments that perform in the PRS-801's wide range.

Measurement Flexibility

Connect to Virtually any 2-wire Fixture or electrode configuration. The PRS-801's simple 0.75" 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 0.75" inch spacing mount directly to the PRS-801 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.

Measurement Speed: Electrification Period

The PRS-801 is one of the fastest measurement instruments in today's precision measurement market. Laboratory tests confirm the PRS-801 can measure from 0 to 1.0x1012 ohms in 2.5 seconds. Thus, its specified electrification period (EP) is 8 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-801 has Automatic, Manual and Auto-Manual operational modes, plus exponential display or standard numeric display in ohms, K-ohms, M-ohms, G-ohms and T-ohms. 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/ORANGE.

Constant Test Voltages

PRS-801 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.

  • <10 Volts: 0.1 to 9.99x103 ohms. <10V is variable across this range from 0.1 mV to 9.99V
  • 10 Volts - Constant Voltage under Load. Constant at 1.0x104 to 9.99x105 ohms. Target calibration is to within ± 0.01 volt, and always within ±1%
  • 100 Volts - Constant Voltage under Load. Constant at 1.0x106 to 2.0x1014 ohms. Target calibration is to within ± 0.01 volt, and always within ±0.1%

Direct Data Download with Included Software

Not only does the PRS-801 make accurate measurements quickly, it documents measurement data immediately or in batch downloads to your Excel® Spreadsheet program. This minimizes transposition mistakes and speeds up precision measurements. The included PROSTAT® CONNECT software is easy to load and use. The PRS-801 connects to your computer's USB port via the included USB 2.0 to RS232 Serial DB9 Converter USB 2.0 to RS232 Serial DB9 Converter.
