When change the calibration value requested push the rotary button ENTER button once more. Confirm with ENTER button rotary button.
Note: When resistance points are calibrated two-terminals way connection the calibrator tostandard

ENTER button rotary button pushed for new value confirmation. Output terminals are automatically switched on
at the same time ready for measuring the selected calibration point
