The PAS-853BRM Digital Surface Resistance Test Kit is the ideal kit for the ESD Plant Auditor. It includes the PAS-853B Wide Range Ohmmeter with 2 each 5 pound Conductive Rubber Electrodes. The PAS-853B instrument is a wide range ohmmeter that measures accurately from 0.01 to 9.99x1012 ohms. The kit is designed to measure resistance point-to-point (Rtt) or surface to ground (Rtg), and meets audit requirements of ESD TR53.

The PAS-853BRM is ideal for making measurements in accordance with test procedures in the following:

  • Floors - ANSI/ESD S7.1- Resistive Characterization of Materials Floor Materials
  • Worksurfaces - ANSI/ESD S4.1 Worksurfaces
  • Compliance Verification - ESD TR53 - Resistance Measurements
  • Floor/Footwear - ANSI/ESD STM97.1 - Floor Materials and Footwear- Resistance Measurement in Combination with a Person
  • Garments - ANSI/ESD STM2.1 Garments
  • Seating - ANSI/ESD STM12.1- Seating - Resistive Measurement
CONTROLS

ON/OFF Battery Bus Cut-off
Slide Switch ON SIDE OF CASE

ON: Energizes instrument and LCD displays Software Version then GO A with AUTO indication (Default)

OFF: Isolates battery and DC voltage from instrument controls and circuit. Use for transport and storage

TEST Pad
With Test Leads installed: Press once & Release.
Measurements performed automatically

In conjunction with MODE changes from Auto operation to Continuous

MODE Pad
Steps through Auto/Voltage ranges with each press of MODE Pad:

AUTO: Default automatic resistance range & Voltage control
<10V: Manual Operation 0.01 to =10V Test Voltage;
Resistance Range: 0.01E-1 to 9.99E9 O
10V: Manual Operation at 10V (Nominal, Semi-Constant)
Resistance Range: 0.98E4 to 9.99E10 O
100V: Manual Operation at 100V (±<5V) Constant Voltage
Resistance Range: 0.98E6 to 9.99E12 O
When data in HOLD, press MODE to terminate HOLD without changing operational mode
Press MODE with TEST to change from Auto to Continuous
Used to measure lead resistance (NULL)
Used by Prostat Authorized Technicians for Voltage Calibration
CONNECTIONS

Positive (+): Test Voltage (RED) – Supplies test voltage to electrodes/fixtures

Negative (-): Current sensing (BLACK) – Conducts current from electrode, fixtures or Ground to instrument

Chassis: Shielding connection to chassis (WHITE) – Reduces transmitted energy and effect on current measurement

Note: ¾ inch spacing between RED and BLACK accommodates dual banana BNC adapters
INDICATION

Colored LED’s indicate instrument operational MODE and Test Voltage (YELLOW) used for the current measurement, as well as measurement completion (GREEN LED).

AUTO: ON during automatic operations; OFF in Manual mode
<10V

100V
GREEN LED: Measurement hold
TYPICAL TOLERANCES

1Nominal performance by range:

0.01E- 1 – 1.0E 0 O <±10%, ±2 Counts
1.0E 0 – 9.99E10 O <±2%, ±2 Counts
1.0E11 – 9.99E12 O <± 10%, ±4 Counts
TEST VOLTAGES

Automatically selected and controlled in AUTO mode. May be manually selected by pressing MODE pad in the following order:

<10V Variable based on resistance load:

Provides 0.001 to =10V
Functional in AUTO within range 0.01 O - <1.0E+4 O
Manual Operation Resistance Range: 0.01E-1 to 9.99E+9 O

10V Constant Voltage (Under Load):

Test Voltage Varies ± <5% in AUTO or Manual Operations
Functional in AUTO within range 1.0E+4O - <1.0E+6 O
Manual Operation Resistance Range: 0.9E+4 to 9.99E+10 O

100V Constant Voltage (Under Load):

Test Voltage Varies ± <2% in AUTO or Manual Operations
Functional in AUTO within range 1.0E+6 O - <1.0E+13 O
Manual Operation Resistance Range: 0.90E6 to 9.99E12 O
Returns to Auto Mode
MODES OF OPERATIONS

GO A: Performs all automatic and manual voltage select functions, stops and displays measurements after Electrification Period (EP) is complete, then displays data with Green LED ON for 10 seconds.

GO C: Performs all automatic and manual voltage select functions, continuously displays measurements until the operator presses MODE or TEST pads. GO C disables electrification period controls.
POWER One 9V alkaline transistor battery; battery life > 50 hours
DIMENSIONS 7.25 in. (184 mm) x 4.3 in, (109 mm) x 1.4 in.
