Analog Input Channels 0 to 15: Thermocouple
− Configurable channels for thermocouple or differential voltage inputs; easy-access
jacks for each channel for quick wiring
− One CJC (cold junction compensation) input for each thermocouple channel
− B, E, J, K, N, R, S, and T thermocouple types supported; the instrument automatically
linearizes the measurements and returns the data as a 32-bit, floating-point
temperature values
− Input range of ±0.075 V (with 0.25 μV RMS A/D noise using no software filtering)
− Break-detection circuitry to detect open thermocouple inputs
Analog Input Channels 16 to 31: RTD
− Configurable analog input channels for RTDs and differential voltage inputs;
easy-access jacks for each channel for quick wiring
− 100 Ω, 500 Ω, and 1000 Ω platinum RTD types supported using alpha curves of 0.00385
(European) or 0.00392 (American)
− 4-wire, 3-wire, or 2-wire configurations; the DT8872 automatically linearizes the
measurements and returns the data as 32-bit, floating-point temperature, resistance, or
voltage values
− Input range of ±1.25 V
Analog Input Channels 31 to 48: voltage
− Direct connection of analog input channels for differential voltage inputs; removable
screw terminal blocks for each channel for quick wiring
− Software-selectable input range of ±10 V, ±100 V, or ±400 V per channel
