• Tare (TARE):
Enabling the Tare function will set the current pressure reading as the zero
reference pressure in order to measure a net change in pressure as opposed to
measuring the gross pressure.
Enabling the Tare feature:
Step 1: Press the On/Off button once to enter the main setup menu.
Step 2: Press (Z) to cycle through the options until TARE is displayed.
Step 3: Press (S) to access the Tare setting options.
Step 4: Press (Z) to toggle between OFF and ON.
Step 5: Press (S) button to apply the displayed option and return to main setup
menu.
NOTE 1: When tare function is enabled, the T5 symbol will appear in the lower
left corner of the display.
WARNING: Do NOT disconnect the gauge from the pressure fitting while the
tare function is enabled. The gauge could still be under pressure
even though the reading shows 0.
NOTE 2: If the maximum gross full-scale pressure value is reached while the
Tare feature is enabled, the PG7 will automatically disable the Tare
feature and return to reading the gross pressure in order to help
prevent the user from accidently overpressuring the gauge.
NOTE 3: Pressing (Z) with the tare function enabled will re-tare the gauge at the
current pressure value.
