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
13
ohms, i.e., 9.99x10
12
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:
• <10 Volts Variable are applied from 0.01 to 9.9x10
3
ohms and provides audible continuity indica-
tion below 1.6 ohms
• 10 Volts ± <0.5V (±<5% Constant Voltage, i.e., Under Load) applied from 1.0x10
4
to 9.99x10
5
ohms
• 100 Volts ± <5V (±<5% Constant Voltage, i.e., Under Load) applied from 1.0x10
6
to <1.0x10
