Transfer curve
The curve shown gives the transmitter
output current as a function of the gas
concentration. If the user connects the
transmitter to a unit other than one that
is provided by ISC Oldham, they
should be certain that the transfer
curve is fully compatible with the input
characteristics of their equipment to
ensure the proper interpretation of the
information provided by the transmitter.
Similarly, the unit should provide
sufficient voltage to compensate for
any voltage drop in the cable.
