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.
