Calibrations

 

Voltage Calibration and Cold Junction Trim have similar functionality.

 

To perform a Voltage Calibration, first select the desired voltage from the drop-down list.  Tapping “?” will display the correct voltage to choose for each T/C type.

 

To select specific inputs for calibration, tap the “Use selected” box, then tap “Select Inputs.”  On the ensuing screen, tap to highlight an input, then tap “Select Highlighted” to mark it for calibration.  Repeat this process for all inputs you wish to calibrate.  Tap “Return” to go back to the Voltage Calibration screen. 

 

Alternately, tap the “All” box from the Calibration screen to calibrate all inputs.

 

Tap to select a Zero or Span Calibration (always perform a zero before performing a span calibration).  Use copper wire for zero and span calibration.

 

Tap “Calibrate” when ready to proceed.  The SDS will show its progress and when the Calibration is completed.

 

To perform a Cold Junction Trim, first select the desired T/C type from the drop-down list.  Use the T/C that is being calibrated for and set the temperature at the nominal value of the operational range.

 

Note that a Cold Junction trim can only calibrate T/C types that the unit is set up for, otherwise the inputs will be grayed out and unavailable.

 

Then tap “Select Inputs.”  On the ensuing screen, tap to highlight an input, then tap “Select Highlighted” to mark it for trim.  Repeat this process for all inputs you wish to trim.  Tap “Return” to go back to the Cold Junction Trim screen.

 

Tap to select a target value.

 

Tap “Calibrate” when ready to proceed.  The SDS will show its progress and when the Calibration is completed.

 

Set Degree Type

Tap the button to toggle between Fahrenheit and Celsius.

 

Datalog Deletion

Tap the Start and End Dates to set the range to delete Datalogs.  When ready, tap “Delete Log Data” or “Delete Survey and Log Data” as appropriate.  Note that this cannot be undone.

 

Shutdown Software

This will shut down the SDS software and return you to the system screen.
