Calibration
The Calibration Menu allows you to configure the sensor for calibration, per-
form the calibration, and view the last calibration and calibration history.
Start Calibration
Select gases and Cal gas values; start a calibration
Cal Gas Values
Enter Cal gas values
Last Cal Results
Shows results for the last calibration
Cal History
Plots the history of gases calibrated
Auto Cal Config
Set Auto Cal timers
Flow Calibration
Used with flow sensor only
Types of Calibration
AMEVision allows you to perform manual, automatic, or remote calibrations.
Automatic and remote calibrations require a factory-provided remote calibra-
tion unit (RCU) that automatically switches the calibration gases for you; manual
calibrations are performed without an RCU, and gases are switched manually.
Manual Calibration
The user defines the calibration gas values and physically switches the gases.
Automatic Calibration
This is an option that allows the system to calibrate itself. The user defines the
calibration gas values, the time each gas will flow through the sensor, and the
frequencies at which automatic calibrations will be performed (for example,
every four hours, every two days, etc.). The system calibrates itself at those pre-
defined times. Do not select Automatic Calibration unless you have a Remote
Calibration Unit (RCU).
Remote Calibration
The user defines the calibration gas values, but interactively determines how
long each calibration gas should flow from the RCU and into the sensor by
pressing
ENTER/MENU to accept the values when the gas is stable. The gases,
however, are automatically switched on/off using the RCU. Do not select Re-
mote Calibration unless you have this option.
Remote and Automatic Calibrations are only available if your analyzer
has an RCU and the ‘
AutoCal ’ option is enabled in the Sensor Con-
figuration menu.
