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. Span may
be adjusted locally using the digital indicator with
range switch.
Output “
᭛”:
Two wire 4 to 20 mA DC output with digital
communications, linear or square root program-
mable. BRAIN or HART FSK protocol are superim-
posed on the 4 to 20 mA signal.
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
-2.5%, 3.6 mA DC or less(Optional
code /F1)
Note: Applicable for Output signal code D and E
Damping Time Constant (1st order):
The sum of the amplifier and capsule damping
time constant must be used for the overall time
constant. Amp damping time constant is adjustable
from 0.2 to 64 seconds.
