pressed, it will display 'cd01'. The 4-digit number represents the last ultrasonic
speed

compensated.

established by the transmit & receive process. The display shows '5.0' mm
(target thickness of the zero plate) and 'CAL' alternately. As soon as the display
value has stabilized, press the 'CAL' key 3-8 to confirm. Then the instrument
