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.
Time Constant (approx. sec) 0.2
