Calibrating Transducers and Servo Valves

Calibrate the 1000-Torr Pressure Transducers

1. Ensure that nitrogen is attached to the

Adsorptive

gas inlet port on the instrument and the

pressure is set to 15 psig.

2. Pressurize the ports.

a. Select

Unit [n] > Show Instrument Schematic

Unit [n] > Enable Manual Control

b. Close all valves (double-click a valve to open or close it).

c. Open valves 4-b and 4-s. Open valve 2 (adsorptive) for 15 seconds.

d. Close all valves.

Verifying the 1000-Torr transducers’ accuracy requires the use of:

• 004-09814-00 Paroscientific Pressure Calibration Standard OR
• 004-09603-00 Crystal Pressure Gauge (if 004-09814-00 is

unavailable)

• 003-09623-01 Vacuum Calibration Standard. (Yellow Jacket)
