PAS-853B Wide Range Ohmmeter Description：

Product Manual Datasheet

Hand Held Wide Range Resistance Meter

The PAS-853B is a wide range ohmmeter capable of measuring from 0.01 ? to 9.99 x 1012 ?, making it a single meter to meet requirements of almost all standards for resistance measurements.

Designed to Support ANSI/ESD S20.20

The PAS-853B is designed specifically for ESD Plant Auditors who must make many measurements quickly while supporting ANSI/ESD S20.20 program standard and periodic verification requirements.

Use it for Packaging per ANSI/ESD 541

The PAS-853B performs in accordance with standard resistance measurement practices outlined in ANSI/ESD S541 Packaging and meets all audit requirements of ESD TR53.

Variable & Constant Test Voltages

<10 Volts Variable from 0.01 to 9.9x103 ohms
10 Volts (±<5% Constant Voltage) from 1.0x104 to 9.99x105 ohms
100 Volts (±<2% Constant Voltage) from 1.0x106 to 9.99x1012 ohms

Double the Number of Measurements

The PAS-853B is a lightweight meter with a built-in electrification period of 3 seconds for measurements from 1.00E-2 ? to 9.99E+5 ? and 8 seconds from 1.00E+6 ? to <1.00E+12 ?, making it a quick and easy way to measure more surfaces throughout your day.

Fully Automatic with an Option of Continuous Mode

The PAS-853B will determine the resistance range and test voltage automatically when you make measurements. After the minimum electrification period, the display will freeze an accurate measurement for 10 seconds. Alternatively, the meter has the option of measuring in Continuous mode, which will continue to measure until Reset is pressed.
