Fresh Air Setup prompt (FAS?)/Pulse Check start screen (PULSE) is displayed, depending on the sensor installed. |
WARNING!
Only carry out the Fresh Air Setup/bump test in fresh, uncontaminated air; otherwise, inaccurate readings can falsely indicate a hazardous atmosphere as safe. If the quality of the surrounding air is uncertain, do not carry out a Fresh Air Setup/bump test. Do not use the Fresh Air Setup/bump test as a substitute for daily calibration checks. The calibration check is required to verify span accuracy.
Failure to follow this warning can result in serious personal injury or death.

•
|
PULSE is displayed shortly. |
|
•
|
The electronic pulse check icon and a countdown are displayed. |
|
•
|
At the end of the countdown, the results of the electronic pulse check are displayed (PASS or ERR). |
If ERR:
|

|
If the bump test fails, calibrate the device (® Section ). |
If PASS:
|
•
|
The device returns to normal operating mode. |

If Calibration Due (CAL DUE) is enabled via MSA Link™ software (default is OFF): |
|
•
|
If calibration is due, CAL DUE will scroll across the display continuously. Press the button to proceed. A calibration is now necessary. |
|
•
|
If calibration is not due, CAL, the number of days, and DAYS will scroll across the display once before proceeding. |
