External Temperature Span. The External Temperature Span is the upper range setting for the external 4-20 milliamp ‘temperature’ input channel. The avail able range is:

English Unit Version: 0.000 to 990.0000 degrees F.

Metric Unit Ver sion: 0.000 to 990.0000 de grees C.

Temperature Span Calibration. The Temperature Span Calibration Value is the 20 milliamp (span) count value from the external 4-20 milliamp ‘temperature’ input channel. This parameter is used to calibrate the span point of the incoming 4-20 signal from the external temperature device. To calibrate the span of the incoming 4-20 signal, press the EDIT key. The screen will display IN20MA. Set the incoming signal for 20 milliamps (or connect an external 4-20 calibrator set for 20 milliamps) and press the EDIT key. The MST2000 will measure the external temperature input channel and save the new 20 milliamp reference to memory.

If an external temperature op tion is pre-installed and calibrated at the factory this will be custom set for that unit.

APZCAL

EX_APS

Absolute Pressure Zero Calibration The Absolute Pressure Zero Calibration value is the 4 milliamp (zero) count value from the external 4-20 milliamp ‘absolute pressure’ input channel. This parameter is used to calibrate the zero point of the incoming 4-20 signal from the external 4-20 absolute pressure device. To calibrate the zero point of the incoming 4-20 signal, press the EDIT key. The screen will display IN4MA. Set the incoming signal for 4 milliamps (or connect an external 4-20 calibrator set for 4 milliamps) and press the EDIT key. The MST2000 will measure the external absolute pressure channel and save the new 4 milliamp reference to memory.

External Absolute Pressure Span. The External Absolute Pressure Span is the upper range setting for the external 4-20 milliamp ‘absolute pressure’ input channel. The available range is:

4175

If an external absolute pressure option is pre-installed and calibrated at the factory this will be custom set for that unit.
