Thermometry
Number of inputs 12 (2 dedicated; 10 scanned)
Input configuration Inputs can be configured independently from the front panel to accept any of the supported input types
Isolation Sensor inputs optically isolated from other circuits but not from each other
A/D resolution 24-bit
Input accuracy Sensor dependent, refer to Input Specifications table
Measurement resolution Sensor dependent, refer to Input Specifications table
Maximum update rate 10 rdg/s on each non-scanned input, 5 rdg/s when configured as 100 kΩ NTC RTD with reversal on; 2 rdg/s on each scanned input; update rate is dependent on the number of channels enabled (typically from 10 rdg/s for 1 channel
to 2 rdg/s for all 10 scanned channels)
Autorange Automatically selects appropriate NTC RTD or PTC RTD range
User curves Room for 39 200-point CalCurves™ or user curves
SoftCal™ Improves accuracy of DT-470 diode to ±0.25 K from 30 K to 375 K; improves accuracy of platinum RTDs to ±0.25 K from 70 K to 325 K; stored as user curves
