(14to158°F)withrelativehumiditywithin30to90%RH

in order to ensure adequate life span and operation.

■ WIRING

•Do not install cables (power supply, input and output)

close to noise sources (relay drive cable, high frequency

line, etc.).

•Do not bind these cables together with those in which

sheet.

•With voltage output, do not leave the output terminals

shortcircuited for a long time. The unit is designed to en-

dure it without breakdown, however, it may shorten ap-

propriate life duration.

CHECKING

the full-scale.

4) Output: Check that the load resistance meets the de-

scribed speciﬁcations.
