Connect the cables from the sensors to the input con-
nectors before turning on the power of the GX-1.
Otherwise, the precision may be lowered.

Notes:
• Connect +S to +BV, and –S to –BV at the sen-
sor when remote sensing is performed, or at the
input connector when not performed. Otherwise,
a correct excitation voltage cannot be obtained.
• Be sure to connect the shield of the sensor con-
nector and the cable shield.
