4.5 Start-Up and Calibration Procedure
1. Verify that the proper electrical connections have been made (See
Section 4.3) and apply power to the M452. Allow the M452 to warm
up for at least 15 minutes.
2. Purge the M452 with zero gas (usually oxygen) at a minimum flow
rate of 0.1 LPM for at least 2 minutes.
3. Check that the Status Outputs (See Section 4.3.4) are in their normal
states and no errors are indicated.
4. Close the zero calibration input (See Section 4.3.3) for a minimum of
1 second to perform the automatic zero calibration.
5. Re-check the Status Outputs to ensure that no errors are indicated.
6. Check the voltage on the analog output (See Section 4.3.2) and verify
that it reads 0.000 ± 0.010 volts.
7. The M452 is now ready for operation.
