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 ow 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 ow. 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.
