3.8 Edit >> System
The Edit System dialog box contains parameters that apply to all of the processes
in a process database. The settings are arranged on a tabbed dialog box.

Sensor: Must be set to the EIES sensor (standard or gas compensating) that the
channel detector module is attached to.
Update: The rate at which readings are returned from the EIES detector. The
detector module takes 1000 readings per second and averages readings between
updates.
Cal Rdg (Readings): The number of detector readings averaged to calculate the
calibration constants. The total calibration time for a channel is 4 times the Cal.
Readings divided by Update.
Start: Starts calibration of the selected EIES detector. Depending on the number
of readings and the channel update interval, calibration may take several seconds.
NOTE: This calibrates the detector electronics assuming no current from
deposition. It is different from QCM calibration, which calibrates detector
readings relative to a QCM while deposition is occurring. Allow a one hour
warm-up for the PMT to reach optimum stability prior to calibrating.
Calibrate Channel: The detector Module channel selected for calibration.
