The TRANSIC111LP performs a self-test. PASS is displayed after termination of the self-test.
Shortly after the self-test, the device is ready for measurement and starts displaying measured
oxygen values. A green LED lights when the transmitter has found the absorption line and can
output valid measured values.
12
Close the device front panel.
13
Ensure the enclosure is closed tight.
