Initial power up

Allow adequate time (approximately 60 minutes) for the heaters to begin operation and
for the transmitter to reach normal operating temperature on power up.
Normal operating temperature for the O
temperature for the combustibles cell is 300 °C (573 °F). The normal sample line
temperature is 170 °C (443 °F). During this time, the eductor air solenoid remains closed so
no sample is pulled through the analyzer. When the transmitter reaches operating
temperatures, the solenoid energizes, eductor air begins to flow, and the unit begins
normal operation.
