cell temperature for single channel configurations and both O
readings for dual channel configurations.
The transmitter probe takes approximately 45 minutes to warm up
to the 1357 °F (736 °C) heater setpoint. The 4-20 mA signal remains
at a default value of 3.5 mA, and the O
through this warm-up period. After warm-up, the probe begins
reading oxygen, and the 4-20 mA output is based on the default
range of 0-10% O
If there is an error condition at startup, an alarm message is
displayed.
