Page 4: Introduction & Description
PAS-853B Wide Range Ohmmeter i. introduction & description The PAS-853B instrument is a wide range ohmmeter that measures accurately from 0.01 to <1.0x10 ohms, i.e., 9.99x10 ohms. In its 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: •... - Page 5 PAS-853B Wide Range Ohmmeter A. Modes of Operation There are two main Modes of PAS-853B Operation 1. AUTO mode (Displayed as GO A): Automatically adjusts resistance range, test voltage and Elec- trification Period (EP). Measurements stops at the end of EP, Green LED is On, measurement is displayed for 10 seconds then instrument resets for the next measurement.

LCD. This is especially impor- tant when making low resistance measurements less than 1.0 or 2.0 ohms. Two 200 cm Prostat leads have a combined resistance of approximately <0.35 ohms. - Page 11 D. To adjust the PAS-853B to compensate for lead resistance connect the leads to the instrument and then short the leads together using the supplied shorting connector (shunt). The instrument should be OFF before starting this sequence.
