Calibration
Calibration procedure using 'cc/sec' units
Please read this entire procedure before proceeding with this calibration routine.
* Follow the instructions of the CalCheck unit, the pointer of the pressure gauge
must resting over the green segment.
* select the 'Custom Cal' symbol from the instruments menu.
* Ensure the instrument is in clean air and then press the ENTER key, the instrument
will Zero, this will take a few seconds but once complete a 'Ready' message will
appear.
* Insert the instruments
probe into the CalChecks outlet and press the ENTER key.
The instrument will automatically sequence through the cold and hot stages of
calibration but when finished gives a summary of values.
* Pressing the ENTER key will return back to the calibration option screen. Press the
ESC key to start using the instrument or press the ENTER key to recalibrate again.
NOTE:
* GasCheck
Tesla can detect changes in Humidity and Carbon dioxide, therefore avoid
breathing on the probe.
Part No. Description Used
A-21500 0.0005 cc/sec Helium Calibration kit For when GasCheck Tesla is used with cc/s units
WARNING: Great care should be taken to ensure the calibration gas is neither pressurised or restricts flow to
the instruments probe. Changes in flow of gas to the sensor will result in significant errors in readings.
