Wide Range. Accurate. Portable.

The PMK-152 Floor Resistance Test Kit contains the instruments you need to take resistance measurements. The PMK-152 includes Prostat's PRS-812 Resistance Meter with 5 pound conductive rubber electrodes. You can take measurements at 10 and 100 volts with accuracy within ±5%. To measure temperature and humidity, the Prostat PHT-771 Digital Psychrometer is also included. The PMK-152 comes with Prostat's unique 10" and 36" electrode spacers, a ground adapter plug, operator's manual, clamps and a variety of useful accessories. It's all self-contained in a sturdy carrying case. The PMK-152 is highly flexible for your general auditing needs. You may customize the PMK-152 by adding various options.

Measurement Range

The PRS-812's accurate wide range of 0.1 to 9.9x10¹² ohms, with capabilities to 1.0x10¹⁴ ohms, offers exceptional 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.
• A wide range audit instrument that meets and exceeds requirements for ANSI/ESD S20.20 and TR53 periodic verification (audit) 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-812 easily exceeds this requirement by as much as 2 decades, depending on program requirements.
• Precision high resistance instrument for Packaging measurements to S541 Standards, for material and product testing, and acceptance verification. Few competitive instruments can measure accurately up to or beyond 1.0x10¹¹ ohms, while the PRS-812 comfortably measures up to 1.0x10¹² ohms.

Measurement Flexibility

Connect to virtually any 2-wire fixture or electrode configuration. The PRS-812'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-812 terminals for measurements with wide range probes and fixtures

Measurement Speed: Electrification Period

Along with the PRS-801, the PRS-812 is one of the fastest measurement instruments in today's precision measurement market. Laboratory tests confirm the PRS-812 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-812 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 >10^12.

Constant Test Voltages

PRS-812 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 1.0x10¹² ohms. Target calibration is to within ± 0.01 volt, and always within ±0.1%

Measurement Convenience & Calculations

Not only does the PRS-812 make accurate measurements quickly, it stores up to 80 measurement data points in its memory. Press the RECORD/RECALL button to retrieve information and calculate attributes of the stored data. Minimum Recorded Measurements. Maximum Recorded Measurements. Average of all Recorded Measurements. The PRS-812 is a convenient, accurate instrument that meets virtually every measurement requirement in the ESD standards world.
