3-3 START-UP

ROM "Checksum" test

 

EEPROM Read/write test

Before proceeding, the operator should be familiar with the keypad and indicators (Section 3-2 on page 3-1).

Operational checks and adjustments are not normally required, provided that the sensor, inter-connection cable and analyzer have been properly installed. The analyzer continually performs self-checking routines during operation.

Calibration with ambient air is recommended after start-up and at regular intervals (see Section 4-2 on page 4-1)

The following sections provide instructions for initial start-up and subsequent standardization of the analyzer.

a.Initial Power-Up

1.Ensure that the proper sensor and sensor cable are connected to the analyzer.

2.Apply power to the analyzer.

The following internal tests are performed:

RAM Read/write test

3.If an error code flashes, refer to the error code lists in Table 3-10 through Table 3-13. Press ACK to continue with the startup procedure.

After internal tests are passed, the software version is displayed for a few seconds, and the analyzer goes directly into RUN mode. "RUN" is briefly displayed, then current oxygen level.

Error codes E-0 (power failure) and E-5 (not calibrated) typically occur upon power-up.

4.Monitor the oxygen output or display until the level stabilizes (typically 5 hours). The alarms and current output levels can be set immediately if desired.

5.Once the sensor has stabilized, the analyzer is operational and is ready for subsequent operations. Refer to Table 3-14 below for the default settings present upon power-up.
