Transmitters OLCT 20
OLCT 20 gas transmitters are equipped with a pre-calibrated sensor and do not require any
adjustment on installation.
However, as gas detectors are safety equipment, it is recommended to bump test the complete
transmitter after a sensor replacement.
3.2.1
Calibration
After removing the sensor from the transmitter, perform the calibration by using the calibrating
bench provided for that purpose (see CALIBRO’s user manual).
