A.2.2 Zero and span adjustment
requirements (HART and Low
Power)
Zero and span values can be set anywhere within the range
limits stated in Table A-1, Table A-2,
Span must be greater than or equal to the minimum span
stated in Table A-1, Table A-2,
A.2.3 Service
Liquid, gas, and vapor applications
A.2.4 4–20 mA (output code A)
Output
Two-wire 4–20 mA, user-selectable for linear or square root
output. Digital process variable superimposed on 4–20 mA
signal, available to any host that conforms to the HART
protocol.
Power supply
External power supply required. Standard transmitter
(4–20 mA) operates on 10.5 to 55 Vdc with no load.

Load limitations
Maximum loop resistance is determined by the voltage level
of the external power supply, as described by:
Max. Loop Resistance = 43.5 (Power Supply Voltage – 10.5)
Voltage (Vdc)
Communication requires a minimum
loop resistance of 250 ohms.
1. For CSA approval, power supply must not exceed 42.4 V.
