Configuration via LCC-S software (option)
An easy and friendly configuration with the software!
It is possible to configure the device.
For example, the instrument could be configured from 30 to 50% RH.
In order to compensate a possible drift of the transmitter, it is possible to add an offset to the displayed value by the HM110 instrument: it shows 48% RH, a standard instrument shows 45% RH. It is then possible, through the software, to integrate an offset of -3 to the displayed value by the HM 110 instrument
To access the configuration via software:
Connect the cable of the LCC-S to the connection of the transmitter.
