Calibration Check

The calibration check is simple and should only take about one minute.
Perform this calibration check before each day's use.
1. Turn ON the Solaris Multigas Detector in clean, fresh air.
2. Verify that readings indicate no gas is present.
3. Attach calibration cap to the Solaris Multigas Detector.
4. Ensure that TOP
"
that "TOP" is positioned at the top of the instrument.
5. Attach regulator (supplied with calibration kit) to the cylinder.
6. Connect tubing (supplied with calibration kit) to the regulator.
7. Attach other end of tubing to the calibration cap.
8. Open the valve on the regulator.
• The regulator flow rate is 0.25 lpm.
• The reading on the Solaris Multigas Detector display should be
within the limits stated on the calibration cylinder or limits
determined by your company.
• If necessary, change cylinder to introduce other calibration
gases.
• If readings are not within these limits, the Solaris Multigas
Detector requires recalibration. See Chapter 4, "Calibration."
