14.4. Connections
Connections differ depending on the input type. Connect standard tools to the measurement input
terminals that are to be adjusted
.
<For ARF2 _ _ AS models>
(1) DC voltage input
Adjustment is done on three input terminals
of each input terminal unit: INPUT CH2, CH5
and CH11.
Connect the INPUT CH2, CH5 and CH11 at
the same time as shown in the figure on the right.
INPUT CH1-4 are adjusted by adjusting
INPUT CH2.
INPUT CH5-8 are adjusted by adjusting
INPUT CH5.
INPUT CH9-12 are adjusted by adjusting
INPUT CH11.
(2) Resistance temperature detector input
Adjustment is done on three input terminals
of each input terminal unit: INPUT CH2, CH5
and CH11.
Connect the INPUT CH2, CH5 and CH11 as
shown in the figure on the right.
Connections to each terminal must be
done separately (not at the same time).
INPUT CH1-4 are adjusted by adjusting INPUT CH2.
INPUT CH5-8 are adjusted by adjusting INPUT CH5.
INPUT CH9-12 are adjusted by adjusting INPUT CH11.
To prevent electric shock, turn off the power source before making connections.
