Automatic Vacuum Calibration System

AVCS^-3SD from Potomac Electric Corporation features a fully automatic pressure and process flow control, as well as data acquisition, from 1.3x10^-3 to 1.3x10⁺⁵ Pa (1x10^-5 to 1000 Torr) with enhanced accuracy.

The pressure control algorithm, integrated controls, calibration and data analysis software are intended to provide a cost effective approach to calibration of vacuum gauges that is NIST traceable, fast and repeatable. AVCS-3DS allows user to develop, store and recall multiple process recipes for each gauge or for a group of gauges and, according to the company, will consistently follow the selected calibration protocol. A built in calibration process log file, in addition to data and process security, provides users with complete supervisory oversight of each process step. AVCS-3SD is fully compliant with ISO 3567.

The system has three process modes and a service mode:

• Automatic mode - Auto selection of set points based on the number of set points per decade. Automatic processing from lowest to highest pressure.
• Semi-automatic mode - Manual entry of set points prior to test. Automatic processing from lowest to highest pressure.
• Manual mode - Manual set point entry (one at a time) with automatic pressure and process control. Each consecutive set point can be set higher or lower than the previous one.
• Service Mode - Manual control of all valves and controllers. Beneficial for step by step system calibration and troubleshooting.
