Chapter 7. PARAMETER SETUP

(2) Turn the DCP301 ON again, and set setup data C q 0 setting to 241. For details on
how to change settings, see 7-1 Parameter Setup (page 7-1).
(3) Display the setup data C q 1 setting.
(4) Press
ENT
to display the difference (A—B) between the resistances of the Zener bar-
rier connected to leads A and B on the lower display.
(5) Press
ENT
to memorize the difference (A—B) between the resistances to the control-
ler.
(6) Press
DISP
to set the DCP301 to the basic display state.
(7) Turn the power OFF, and remove the short across A and B.
• The resistance error of the Zener barrier connected to leads A and B cannot be
adjusted unless it is 20Ω or less.
• This adjustment is not required when a Zener barrier and an input other than
an RTD are not used.
• Once the Zener barrier has been adjusted, compensation is carried out on the
Zener barrier. When using on an RTD without a Zener barrier, re-adjust without
the Zener barrier.

Short-circuit
● C q 1 (Input 1 Zener barrier adjustment)
The following adjustment must be made when using a Zener barrier.
(1) Turn the DCP301 OFF. When you have finished mounting and wiring the DCP301,
short-circuit across A and B on the terminals of the RTD.
