Calibration Wizard

The Calibration wizard, opened from the Connect Screen’s Datalogger menu, is used to assist in the calibration of one or more variables in the datalogger program. This calibration tool is available only for the CR1000X-series, CR6 series, CR300-series, GRANITE 6, GRANITE 9, GRANITE 10, CR1000, CR3000, CR800-series, CR5000, and CR9000X dataloggers that support the FieldCal instruction.

The program running in the datalogger must contain one or more FieldCal or FieldCalStrain instructions for the variables you wish to calibrate. One function of this instruction is to write a programname.cal file to datalogger memory that contains information on the variables to be calibrated and the most recent calibration values. The Calibration wizard looks for a *.cal file with a name that matches the program currently running in the datalogger. If a matching file is found, the calibration wizard will use the information from that file to walk you through each step of the calibration. Calibration options offered in the FieldCal instruction are zeroing, offset, two-point multiplier and offset, and two-point multiplier only. Calibration options offered in the FieldCalStrain instruction are zeroing, 1/4 bridge strain shunt, bending 1/2 bridge strain shunt, and bending full bridge strain shunt.

More information on calibration and zeroing is found in Calibration and Zeroing. Also, refer to the datalogger’s CRBasic help file for additional information on the FieldCal and FieldCalStrain instructions, and to the LoggerNet help file if help is needed while using the Calibration wizard.
