1 Year Total Accuracy Specifications at TCal ±5°C & Range Parameters Range Typical Output Stability (Accuracy relative to calibration Standards) Range Notes Note 1 : Allowance must be made for output resistance when driving into a load. Note 2 : Limited by 50 Ohm output impedance. Note 3 : Internally adjustable from 2mA to 30mA - Factory set to 20mA as standard. For safety the trip is controlled by a fail-safe circuit independant of the processor which shuts the high voltage output off in the event of an overload. Note 4 : Typical RMS noise figures at 50% of full scale, bandwidth 1 to 10Hz. High...
