Millivolt Source 0 to +/- 80mV
Accuracy 0.02% of f.s. (16uV)
Resolution 5uV
Output resistance 10 ohm
Note: For output settings below 8mV an increased resolution of 0.5uV is automatically
switched in. The accuracy for this part of the span is also increased to +/- 4uV
Milliamp Source 0 to 80mA
Accuracy 0.02% of f.s. (16uA)
Resolution 5uA
Maximum load (24V drive) 300R/80mA, 480R/50mA, 1.2K/20mA
Inching
Three levels of increment, 0.1, 1 or 10 for degC/degF, and 1, 10 or 100 uV/uA for voltage
current. The lowest of these represents the highest setting resolution and provides the most
precise control of the output.
24V process loop drive mode
A process loop can be driven at 24V up to 60mA by selecting the Milliamp source mode and
setting it at 60mA (or a lower level if required).
PT100 SIMULATION
14 set temperatures. Specification within ± 0.1% of DIN 43760 resistance values on all
settings.
