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) 0.4 0.3 0.3

Supply & Load Requirements “ ᭛”:
* Safety approvals can affect electrical requirements.
See Section 6.6, ‘Power Supply Voltage and Load
Resistance.’
Supply Voltage “
᭛”:
10.5 to 42 V DC for general use and flameproof type
10.5 to 32 V DC for lightning protector (Optional code
/A)
10.5 to 30 V DC for intrinsically safe, Type n,
nonincendive, or non-sparking type
10.5 to 28 V DC for TIIS intrinsically safe type

Communication Distance;
Up to 2 km (1.25 miles) when using CEV polyethyl-
ene-insulated PVC-sheathed cables.
Communication distance varies depending on type
of cable used.
Load Capacitance;
0.22 µF or less (see note)
Load Inductance;
3.3 mH or less (see note)
Input Impedance of communicating device;
