6.4.1.7 Tare Button
If the Tare calibration function has been chosen in the Display Settings App (section 6.4.4), then the Tare
Button [
] will appear in the channel screen. For safety reasons, the tare button will be highlighted
in yellow when active. The Tare button and the Zero Button cannot appear on the screen at the same
time. When the Tare button is pressed, the instrument will subtract the current pressure reading (the tare
pressure) so that the indicator will display zero. Subsequent deviations in pressure will be relative to the
tare pressure.

Pressing the tare button again will deactivate the tare and change the pressure indication back to the
reading corresponding to the calibrated output of the transducer. An active tare will revert to a deacti-
vated state after a power cycle.
