30. Click ‘ZERO’ button again.
31. Click ‘SAVE’ and overwrite existing calibration le by continuing to click ‘OK’ as dialogs appear.
32. Click ‘DONE’ to exit calibration dialog box.
Torque calibration is now complete. If the readings do not correspond with the procedure or are not within
acceptable limits, contact SuperFlow Customer Service.
Pressure Transducers:
If you have pressure sources and calibrated
pressure measurement equipment with a higher
accuracy than the transducer, it is possible
to calibrate the pressure sensors using the
procedures similar to those used to calibrate the
torque sensor. However, scroll and locate the
desired pressure channel and apply a known
pressure to the sensor within range to verify calibration.
Atmospheric Transducers:
Check the calibration of the weather channels, AirInt, Humidy, and BaroP using a weather station of your
choice.
– AirInt is calibrated via the AirSen channel 1.
– Humidy is calibrated via the HumSen channel 6.
Raise or lower the voltage values in either channel to perform calibration. SuperFlow uses a Kestrel
3500 pocket weather station to calibrate these channels. Any similar device will su󰀩ce.
Temperature:
There is no adjustment for the calibration of the temperature sensors. If a temperature is reading
incorrectly, try using a di󰀨erent probe. If available, the temperature may be veried with a thermocouple
simulator. If that does not work, contact your SuperFlow representative.
Speed:
There is no adjustment for the calibration of the speed sensor. If the speed is reading incorrectly, check the
cables, connectors, and, if possible, the gap between the pickup and the gear. If it is still reading incorrectly,
repair parts or service may be required. If available, the speed may be veried with a hand tachometer.
Speed pickup gap .015"-.020"
An abrupt change in pressure may result in
damage to the sensor being calibrated. Make
certain that the regulated air supply is set to zero
before introducing pressure at a slow pace. When
nished calibrating, slowly bleed o󰀨 the air supply
before removing from the sensor being tested.
