Hey folks, today it's the Macurco CM-1XLS CO detector up for calibration and bump.

First part goes through calibration, then I show how to run a bump test and why you should purchase a cylinder of higher PPM CO to do bump tests with if you run them as part of your daily program (which you should be doing).

To calibrate:
1. Press and hold button to turn on
2. Wait for normal reading mode
3. Press power button once, wait for test to finish
4. When screen says CAL, press button
5. Wait for zero to finish
6. When screen shows SPN, press button, attach calibration adapter, open regulator valve
7. Wait 2-3 mins for calibration to finish
8. When alarm goes off and shows 35ppm, turn off gas and remove calibration adapter.
9. All set!
