10.4.7 Display which corresponds to 20mA
output:
20 . 000
The Rate Totaliser display which corresponds to a
20.000mA output current is defined by this function.
Using the

20 . 000
in the
4/20mA output sub-menu and press
(
which will
reveal the existing rate or total display with one digit
flashing. The required display can be entered using
the

push button to adjust the flashing digit
and the

digit. When set as required press

Notes:
1. If the calibration of the rate or total display
defined as the source for the 4/20mA output
is changed, the 4/20mA output will
automatically be set to give a constant 3.5mA
output irrespective of the display. The
4/20mA output should always be
reconfigured following reconfiguration of the
source display.
2. If the Rate Totaliser and the 4/20mA current
sink output are powered from separate
supplies, the 4/20mA output current will
continue to flow when the Rate Totaliser
supply fails or is turned off. Powering both
from a common supply eliminates this effect.
