Calibrate logger

SiteView software provides two-point calibration for most of the loggers. If the source signal like voltage or current can be connected to the logger while the logger is connecting to the computer, you can calibrate the logger on-line. If the source signal like a temperature or relative humidity is not available for on-line calibration, you can calibrate the logger off-line after the logger has recorded the low and high point data.

On-Line Calibrate

Click Calibrate button on the top of the logger status page in SiteView and choose On-Line Calibrate menu.

The following dialog appears:

Select the channel you want to calibrate on and click OK button. The following dialog appears:

The above page allows you to calibrate the low point. Please adjust your input which connects to the channel terminal strip to a low point value closes enough to the lowest value of the channel. In the above example “0” is the lowest value.

Click Start Calibration button to start the low point calibration. After the click, Start Calibration button changed to Stop Calibration.

During the calibration process the current real-time value is showing in Current Reading field. If you think this value is stable you may click Stop Calibration button.

Click Next to proceed to the next page.

The above page allows you to calibrate the high point. Please adjust your input which connects to the channel terminal strip to a high point value closes enough to the highest value of the channel. In the above example “50000” mV is the highest value.

Click Start Calibration button to start the high point calibration. After the click, Start Calibration button changed to Stop Calibration.

During the calibration process the current real-time value is showing in Current Reading field. If you think this value is stable you may click Stop Calibration button.

Click Next>> to proceed to the next page.

The above page shows all parameters you have input as well as the values the system have calculated. Two important values can be saved back to the logger by clicking Save Parameters to the logger. Those two parameters are: Calibration Low Value and Calibration High Value.

If you click Save Parameters to the logger button you will get the below warning dialog. Click Yes to confirm the saving process.

If the system saved the parameters back to the logger successfully, at the bottom side of the dialog The calibration is finished! will appear.

You may click Done button to close the dialog.

On the logger status page the Cali. Low and Cali High values for this channel were updated with the new values.

The calibration is finished!

Off-Line Calibrate

Click Calibrate button on the top of the logger status page in SiteView and choose Off-Line Calibrate menu.

The following dialog appears:

In Step 1, it instructs you how to configure the logger to record low and high point values and retrieve them in the downloaded file.

Once you have obtained those four parameters, enter them into their fields respectively. Click Calibrate button to calculate the final parameters and save them back to the logger. The following dialog appears:

Click Yes button to save the parameters.

The calibration is finished!
