Performing System Calibration
When satisfied with the system inventory and calibration configuration, begin the calibration process by
clicking the Start Calibration button to open the System Calibration window. The fields in the Calibration
Parameters area indicate the current setting for each Chassis, Channel, Gain and Bipolar setting in the
system. These fields are described below:
• Chassis: This field indicates which chassis is currently
scheduled to be calibrated. Initially, the chassis will be
set to "Main" to indicate the WaveBook main chassis.
• Channel: This field indicates which channel is
currently scheduled to be calibrated. The value of this
field will correspond to the current channel number
regardless of the current chassis unless concurrent
calibration was selected for the current chassis. In this
case, the value of field will be "All" indicating that all
channels on the current chassis will be calibrated
concurrently.
• Gain: This field indicates the current gain value
scheduled to be calibrated. The value of this field
initially starts at 1 for each channel being calibrated
and will go up the maximum gain value for the current
chassis.
• Bipolar: This checkbox indicates the current polarity
scheduled to be calibrated. Both bipolar and unipolar
polarities are calibrated for each gain value. This
value initially is set to unipolar for each gain and will
subsequently toggle to bipolar for the current gain
value.
WaveCal - System Calibration Dialog Box
WaveCal automatically updates the current calibration parameters depending on their current settings and
user events. Calibration is controlled by the following command buttons:
• Test Voltage: This button may be used to test channel voltage levels both before and after calibration.
This command will display the current voltage level for the current channel(s). If concurrent calibration
has been selected for the chassis, then the voltage levels for all 8 channels for the current chassis will
be displayed. Otherwise, only the voltage level for the current channel will be displayed. A sample test
is shown below:
