Escort 2030 calibration process differs from later Agilent/Keysight U1401A/U1401B.
For example, pressing SHIFT after entering Calibration mode does nothing. You need to previously select Output mode and enter Calibration mode after to get -rDy- CAL-0.
But I'm stuck in this mode, any keypresses just switch between CAL-0 and 00000 readings on the main display, no way to get further.
Any info on calibration mode of this process calibrator?

P.S. Found Extech CMM-17 and AKTAKOM 7030 to be the same device.
