Page 27: Calibration
Once this calibration data is stored, the input measurement and the signal source can be adjusted back to the most accurate value. The LDS-Dactron system uses sigma-delta A/D and D/A converters and an anti-aliasing filter with a very high cutoff frequency. As a result, the amplitude characteristics of the input and output are not frequency dependent. -

This will open the normal Calibration screen and dialog informing you to allow the Front-End DSP Box to warm up for at least 10 minutes; click on OK to access the Calibration screen. Before pressing the button, Start measure the DC voltage offset on the OUTPUT channel.
- Page 32 Calibration DC Measurement for Offset Calibration You will also be requested to measure the RMS value of the output at the AC 10 Volt full-scale range and type it into the dialog box. Please make sure that the voltmeter is switched to AC measurement. This concludes the calibration of the OUTPUT channel.
- Page 33 Calibration Input Channel Calibration The input channels are calibrated automatically. The system will now use the calibrated OUTPUT channel as the signal source. The gain error and offset estimation are calculated automatically for all the input range settings. The input calibration process depends on an accurately calibrated OUTPUT channel.
- Page 34 Calibration AC Measurement for the Gain Validation After validation, both the offset and gain error should be within tolerance. The pass/no-pass tolerance used during the validation is: 10 volt range: 1% of the Full Scale 1.0 volt range: 2% of the Full Scale Low-voltage Range Calibration has low voltage input ranges of 0.1 V and 0.01 V.
- Page 35 Calibration … Cable Connection for Low-voltage Range Calibration The dialog boxes below ask for a measurement and entry of the DC and AC reading from the meter. These measurements will be used for the Output Channel calibration so that the low voltage Input Channel calibration is provided with an accurately calibrated signal source.
