Notes
1) Once a measurement procedure has been started, the menu selection is blocked.
2) During a measurement procedure (after Start has been pressed), you can switch
between functions. This permits, for example, the observation of the Min/Max
function during data logging.
3) The Clear key has no function in the absolute pressure instruments.
4) The AVERAGE function creates an arithmetic average value of all measured values
during the time period selected in the menu. After expiry of the time period, the
average value will be displayed.
5) Measurement of the leak rate (diff/gauge sensor) or tendency (abs. sensor). The
pressure change (CHANGE RATE) from the start time to the current time will be
displayed. The first display occurs 10 s after the start.
