T1001.EPS Values in absolute for EJA510A.
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 commu-
nications, linear or square root programmable.
BRAIN or HART FSK protocol are superimposed 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
