5.9.3.2. ANALOG OUTPUT CALIBRATION
Analog output calibration should to be carried out on first startup of the analyzer
(performed in the factory as part of the configuration process) or whenever recalibration
is required. The analog outputs can be calibrated automatically, either as a group or
individually, or adjusted manually.
In its default mode, the instrument is configured for automatic calibration of all
channels, which is useful for clearing any analog calibration warnings associated with
channels that will not be used or connected to any input or recording device, e.g.,
datalogger.
Manual calibration should be used for the 0.1V range or in cases where the outputs must
be closely matched to the characteristics of the recording device. Manual calibration
requires the AUTOCAL feature to be disabled.
Automatic calibration can be performed via the CAL button located inside The AOUTS
CALIBRATION submenu. By default, the analyzer is configured so that calibration of
analog outputs can be initiated as a group with the AOUT CALIBRATION command.
The outputs can also be calibrated individually, but this requires the AUTOCAL feature
be disabled.
5.9.3.3. ENABLING OR DISABLING THE AUTOCAL FOR AN INDIVIDUAL ANALOG
OUTPUT
To enable or disable the AutoCal feature for an individual analog output, elect the
ANALOG I/O CONFIGURATION submenu (see Figure 5-3) then press:
