PRS-812B Resistance Meter Description：

Product Manual Datasheet

The ideal choice for the ESD Auditor

The PRS-812B Resistance Meter delivers the full-featured functionality and advanced measurement capabilities that ESD Auditors need. It puts a lot of testing power in your hands to quickly and 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 and ANSI/ESD STM97.1.

Fully automatic for peace of mind

The PRS-812B uses 3 modes of measurements: Automatic, Manual and Auto-Manual. When measuring in Automatic mode, the resistance range and test voltage is automatically selected for you. Auto mode gives you peace of mind and saves you time.

A very accurate resistance meter

The PRS-812B’s wide range meter offers fast, accurate resistance testing using the included high quality 10 foot test leads. The low resistance range is designed to measure from 0.10 to 1.0x104 Ω.The PRS-812B also meets ANSI/ESD S20.20 and TR53 procedure requirements from 1.00x103 to 1.00x1011 Ω. Measurement guidelines require accurate measurements one decade above the resistance requirements of a facility’s ESD program.

Under load test voltages

Uses constant voltage under load for 10 volts and 100 volts with an accuracy of ± .05%, meeting the requirements of ANSI/ESD S20.20 resistance testing for product qualification and compliance verification. The low resistance range uses variable voltage from 0.1 mv to 9.99 V.

Long lasting battery

The PRS-812B uses a 3 cell Li-ion battery pack that will last typically 480 hours, taking more than 8,000 measurements before you will need to charge it. Charging is accomplish without removing the battery pack, using the included USB cable and wall charger. The Micro USB cable allows you to charge the PRS-812B via the USB port of your computer. Also included is a wall charger with interchangeable AC blades for global use that includes North America, Europe, United Kingdom, Australia, and China.
