Wide Range. Accurate. Portable.
The widest range portable constant voltage resistance instrument in today’s market, the PRS-801B is the choice of most ESD professionals. Why? Because the PRS-801B 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-801B’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 PAS-853S Test Lead Shunt is used to remove any resistance in the test leads and get the most accurate reading.
- 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-801B easily exceeds this requirement by as much as 3 decades, depending on program requirements.
3. 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-801B’s wide range.
Measurement Flexibility
Connect to Virtually any 2-wire Fixture or electrode configuration.
The PRS-801B’s simple ¾ 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 ¾ 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
Measurement Speed: Electrification Period
The PRS-801B 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
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.
- <10 Volts: 0.1 to 9.99x103 Ω
<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 Ω - 100 Volts – Constant Voltage under Load
Constant at 1.0x106 to 2.0x1014 Ω
High Quality Test Leads
The 30 inch high performance test lead harness is designed for PRS-801B precision high resistance measurements in the 1011 to 1014 range. It includes a shielded (-) negative test lead for accuracy and minimum electrical interference from personnel and equipment. The shield is connected directly to the PRS-801B instrument reference and fixture ground.
Direct Data Download with Included Software
Not only does the PRS-801B 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 2.0 software is easy to load and use. The PRS-801B connects to your computer’s USB port using the provided USB cable.
In the Auto Connect mode, you can control the PRS-801B measurement sequence so that each data point is downloaded to the spreadsheet at the conclusion of each measurement. The Spreadsheet cursor automatically moves to the next data entry cell in preparation for the subsequent measurement.
Once as many as 999 data points are stored in the PRS-801B’s memory, they can be downloaded to a spreadsheet at a later time. Each data point will be placed in its own spreadsheet cell.
When CONNECT 2.0 is used, a backup Text file is maintained for every measurement set, its date, time and location should you desire.
The CONNECT 2.0 utility is compatible with 32-bit and 64-bit version of Windows from XP all the way to Windows 10.
