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.
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).
