Honeywell Digital (DE) Mode
Reproduces the transmitter signal exactly to within its
resolution
Display 6 digits numeric indication
Display Resolution 0.01 unit for reading range (-999 to 999)
0.1 unit for reading range (-9999 to -1000) or (1000 unit to 9999).
1 unit for reading range (-99999 to -10000) or (10000 to 99999 ).
10 units for reading range (-999999 to -100000 ) or (100000 to
999999).
Display Update Rate 2 seconds
Display Indication Accuracy 0.1% of calibrated span (+/-1 digit)
Maximum Meter Voltage 30V DC
Max Loop Voltage Drop
≤
2.3V @ 21.5mA
Min Loop Operating Current 3.6mA
Power Fail
All calibration constants are stored in non-volatile memory
and are not affected by power loss.
Failure mode LCD display failure will not affect transmitter operation
Reverse Polarity Protection Yes
Loop Supply Voltage
Requirement
Min. loop voltage = 2.3Vdc + (Rloop * 22mA)
Where:
MinVTx is the transmitter minimum supply voltage
Rloop is the resistance on the loop (in ohms)
Display Performance
The LCD display will turn blank below -20 °C and above
70 °C
(-4°F and 158°F), rendering the display unreadable.
However the loop will continue to function.
