Change Type and
Connections
The
Connections
command allows the user to select the sensor type and
the number of sensor wires to be connected from the following list:
• 2-, 3-, or 4-wire Pt 100, Pt 200, Pt 500, Pt 1000
(platinum) RTDs (
= 0.00385
/
/°C)
• 2-, 3-, or 4-wire Pt 100, Pt 200 (platinum) RTDs (
= 0.003916
/
/°C)
• 2-, 3-, or 4-wire Ni 120 (nickel) RTDs
• 2-, 3-, or 4-wire Cu 10 (copper) RTDs
• IEC/NIST/DIN Type B, E, J, K, R, S, T thermocouples
• DIN type L, U thermocouples
• ASTM Type W5Re/W26Re thermocouple
• GOST Type L thermocouples
• –10 to 100 millivolts
• 2-, 3-, or 4-wire 0 to 2000 ohms

Output Units
The
Snsr 1 Unit
and
Snsr 2 Unit
commands set the desired primary
variable units. The transmitter output can be set to one of the following
engineering units:
• Degrees Celsius
• Degrees Fahrenheit
• Degrees Rankine
• Kelvin
• Ohms
• Millivolts
Sensor 1 Serial Number
The serial number of the attached sensor can be listed in the
Sensor 1 S/N
variable. It is useful for identifying sensors and tracking sensor calibration
information.
Sensor 2 Serial Number
The serial number of a second sensor can be listed in the
Sensor 2 S/N
variable.
2-Wire RTD Offset
The
2-wire Offset
command allows the measured lead wire resistance to
be input, which results in the transmitter adjusting its temperature
measurement to correct the error caused by this resistance. Because of a
lack of lead wire compensation within the RTD, temperature
measurements made with a 2-wire RTD are often inaccurate.
