Tare Function DG-10-E
In this mode the positive deviation of the measured value from the tared value (max. 20% of
the measuring range) is constantly indicated by the main display. The untared pressure value
is always shown on the bar graph display. Thus the digital gauge’s actual working load can be
read off even if the tare function is active. When the tare function is active, a function
indicator appears on the display. There are 2 possible ways of activating this mode:
1) Select the tare function and set the value to be tared using the keys .
When set, the measured value to be tared is backed up as tare. The main display and the
auxiliary display then show the value “0000” in the unpressurised state.
Example: If a value to be tared is set as 2 bar, the main display indicates 0 bar in the
unpressurised state.
2) Load the digital gauge with the pressure to be tared.
The current measured value appears in the main display field of the main display. Select
the tare function and then operate both keys simultaneously . The current
measured value will be backed up as tare. The main display and the auxiliary display are
set to (0000).
Setting the tare value to (0000) resets the tare function in both models.
