3-3 START-UP
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
ROM "Checksum" test
EEPROM 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.
