Operating modes
Automatic update
Repetitive update of measured quantity based on the „Fix time“
External synchronisation
Measuring cycle is reset via an external 0V clock pulse. The display is then blanked. A new measuring
cycle starts when the clock goes high with the measured value being displayed as normal.
Single measurement
Following an external reset signal, the instrument calculates the measured quantity once. The display is
maintained until the falling edge of the next reset pulse.
The modes ”external synchronisation” and ”single measurement” are not possible with options K4 and K16.
