    Has been replaced with the PAS-853B Wide Range Ohmmeter

    The PAS-853 is Beautifully Designed
    Beautifully Designed
    This digital wonder is designed specifically for the plant ESD auditor who needs to make many measurements quickly. Its design and accessories reduce inconvenient weight and time required for routine measurements.

    The PAS-853 instrument is a wide range ohmmeter that measures accurately from 0.01 to 1.0x1012 ohms. In AUTO mode the instrument automatically adjusts resistance range and selects test voltage in accordance with standard practices outlined in ANSI/ESD STM11.11, and meets audit requirements of ESD TR53:

    • 10 Volts Variable applied from 0.01 to 9.9x103 ohms and provides audible continuity indication below 1.6 ohms
    • 10 Volts ± <4V applied from 1.0x104 to 9.9x105 ohms
    • 100 Volts ± <3V (Constant) applied from 1.0x106 to 1.0x1012 ohms

    Used with two multi-conductor well insulated test leads, the PAS-853 is easy to use and makes fast measurements with minimum effort.

    A Most Convenient Auditing Instrument
    Using Prostat's highly flexible, multi-strand leads, the PAS-853 makes all conventional TR53 audit measurements with a simple Press & Release of its TEST pad. Combine the leads with your current 5 lb. electrodes, fixtures, clips and clamps for your periodic measurements. Conveniently connect your specialized fixtures directly to the instrument using dual banana plug adapters. A Most Convenient Auditing Instrument

    It can also be used with optional fixtures integrated into the instrument to reduce weight, cost and enhance simplicity.

    With integrated fixtures installed, Prostat’s PAS-853 Resistance Auditing System incorporates a unique pressure sensor to actuate measurements, eliminating the need for a 5 pound electrode, fixture weights and test leads. The new PAS system simplifies plant periodic verification and makes the audit process more convenient. It supports ESD TR53 Compliance Verification of ESD Protective Equipment and Materials. PAS was designed by Professional ESD Auditors, for ESD Auditors.

    Technical Specifications

    ON/OFF Battery Bus Cut-off

    Slide Switch ON SIDE OF CASE
    ON: Energizes instrument and LCD displays Software Version then
    GO with AUTO indication (Default)

    TEST

    When sufficient* pressure is applied measurements start at low voltage and display the value (e.g. 1.2E4) as well as the voltage in use. Used in conjunction with CAL?

    MODE

    Steps through Auto/Voltage ranges:
    • AUTO: Default automatic resistance range & Voltage control
    • <10V: Manual Operation 4mV to =10V Test Voltage; Resistance Range: 0.0E-1 to 1.0E9 ? @ approx. 8V
    • 10V: Manual Operation at 10V (Nominal, Semi-Constant) Resistance Range: 0.9E4 to 1.0E10 ? @ 6 to 10V
    • 100V: Manual Operation at 100V (±3V) Constant Voltage Resistance Range: 0.9E6 to 1.0E12 ?
    • When data in HOLD, press MODE to terminate HOLD without changing operational mode
    • Used to enter fixture or lead resistance NULL mode and Pressure calibration CAL? Mode.

    CONNECTIONS

    Lead Terminals: Positive (+) Test Voltage and Negative (-) current sensing at front end of instrument. Note ¾ inch spacing to accommodate dual banana – BNC adapters

    Fixture Terminals: Four PAS fixture receptacles located on bottom of instrument case

    RESISTANCE RANGE TOLERANCE

    0.1E- 1 -- 1.0E 0 ? <±10% ±1 Counts Nominal ±5%
    1.0E 0 -- 1.0E11 ? <± 5% ±2 Counts Nominal ±2%
    1.0E11 -- 1.0E12 ? <± 20% ±5 Counts Nominal ±10%

    Nominal represents typical overall performance across measurement range under test lab conditions
