1. Analog Output Setting Mode [ *RANGE ]
The analog output has output 1 and output 2. Only output 1 can be used for communication
purposes.
Set a range appropriate for 4-20 mA DC output signals. The range has two setpoints: the lower
limit (zero point) of the range corresponding to the minimum (0%) of a given output signal and the
upper limit (span point) of the range corresponding to the maximum (100%) of the given output
signal.
(1) Output1
[*OUT1]
(a) Select a parameter to be output.
・ Physical density [*DENS]
・ Compensated density [*C_DNS]
・ Specific gravity [*SP_GR]
・ Calorific value [*CALRY]
・ Molecular weight [*MOL]
・ Concentration [*CONCT]
・ Gas temperature [*TEMP]
・ Gas pressure [*PRESS]
(b) Set the zero and span points. (This item is not applied if temperature or pressure are cho-
sen as the parameter in item (a) above.)
