Advice for Device Operation
Do take note of what gas calibration setting is selected on mass and
volumetric devices.
Do consider that changing or mixing gases can reduce accuracy and give
unexpected results with mass and volumetric devices. Please see the
manual for instructions on correcting to alternate gas viscosities.
Do tare the unit often, while making sure there is absolutely no flow during
the tare (a controller will tare on a zero setpoint command).
Do keep the unit under 125 PSIG. For pressure gauges and pressure
controllers the unit’s pressure should be within its full scale range. Units
special ordered for low pressure use may have reduced pressure limits.
Do keep units running for best performance.
Do consider adjusting your controller’s P & D valve settings to suit your
system's requirements, note the initial settings before adjustment.
NEVER leave a controller with a non-zero setpoint if no pressure is available
to make flow. The controller will apply full power to the valve in an attempt to
reach the setpoint. This can make the valve very hot.
Do follow your recalibration schedule.
