<9. General Specifications>
9-2
IM 01C25F01-01E
Failure Alarm “◊”
Output status at CPU failure and hardware
error;
Up-scale: 110%, 21.6 mA DC or more
(standard)
Down-scale: –5%, 3.2 mA DC or less
Note: Applicable for Output signal code D and E
Damping Time Constant (1st order)
Amplifier damping time constant is adjustable
from 0 to 100.00 seconds and added to
response time.
Note: For BRAIN protocol type, when amplifier damping
is set to less than 0.5 seconds, communication
may occasionally be unavailable during the
operation, especially while output changes
dynamically. The default setting of damping
ensures stable communication.
Update Period “◊”
45 ms
Zero Adjustment Limits
Zero can be fully elevated or suppressed, within
the lower and upper range limits of the capsule.
External Zero Adjustment “◊”
External Zero is continuously adjustable with
0.01% incremental resolution of span. Re-range
can be done locally using the digital indicator
with range-setting switch.
Integral Indicator (LCD display)
5-digit Numerical Display, 6-digit Unit Display
and Bar graph.
The indicator is configurable to display one or
up to four of the following variables periodically.;
Pressure in %, Scaled pressure, pressure in
Engineering unit.
See “Setting When Shipped” for factory setting.
