Taring Your Flow Controller
Taring is an important practice that ensures that your ow controller is
providing the most accurate measurements possible. This function gives the
ow controller a good zero reference for ow measurements. For controllers
with a barometer, taring can also be used to align the internal absolute
pressure sensor with the barometric pressure reading.
How to Tare
When auto tare is -ON- your ow controller automatically
tares its ow rate whenever it has a zero setpoint for more
than 1.2 seconds. For manual tares, follow these steps:
1. Ensure that nothing is owing through the device,
usually by giving the controller a zero setpoint.
2. MENU > TARE> TARE FLOW. Flow tares should occur at the
expected process pressure, as long as there is no ow.
3. MENU > TARE> TARE PRESS Absolute pressure tares must be
done with the controller open to atmosphere.
When to tare
• After signicant changes in temperature or pressure.
• After installing the controller in a dierent orientation.
• After dropping or bumping the ow controller.
