Operation Model 7600
Teledyne Analytical Instruments 62
When a channel enabled for auto calibration is in the calibration
mode, a message indicating ZERO cal. or SPAN cal. will appear on the
measurement screen. For example, if channels 1 and 2 have the auto
calibration setting enabled, when the calibration event takes place, both
channels 1 and 2 will indicate ZERO cal. when the zero calibration is
being performed. Zero calibrations are performed first and all enabled
channels will zero simultaneously.
When the zero calibrations are finished, channel 1 will enter the
span calibration followed by channel 2.
