CAL

 

Calibration

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

In this mode you can

 

 

 

 

 

 

1. Calibrate the instrument using a mV source - rcAL or ref source cal.

 

 

2. Offset the calibration to account for errors in actual sensor

 

 

measurement and a ref sensor - UCAL or user calibration

 

 

3. Return to factory set calibration - FACT or factory set calibration.
