Temperature Measurement It can : Measure/Source millivolts (0 to ±199.99 mV) Measure/Calibrate in °C/°F (-270 °C to +1820°C, -454 °F to +3308°F) Measure/Source milliamps (0 to 19999 µA) MICROCAL is a state-of-the-art instrument featuring a microprocessor based closed loop design. This means that the programmed output is continuously compared with a highly stable reference, and automatically corrected for any errors. Thus the accuracy achieved is extremely high : typically, better than ±0.02% of FS. Further, use of the microcomputer allows direct display in °C/°F of thermocouple and RTD inputs, as well as automatic and manual cold-junction compensation for thermocouples. The use of membrane keypad for function selection and setting instead of mechanical push button switches greatly enhances reliability. In this mode the instrument displays the linearised temperature of the thermocouple or RTD sensor on the display. The units can be °C or °F. For thermocouples, the cold junction temperature can be automatically corrected for, or set manually. Millivolts Measurement The measured millivolts of a thermocouple or any source can be displayed directly. Calibration in °C/°F In this mode MICROCAL generates the emf corresponding to any required temperature for the selected thermocouple. This can be referenced to any cold junction temperature manually. It can also be automatically compensated. Millivolts Source The required millivolts (-199.99 to 199.99 mV) are directly sourced. Milliamps Measurement C1014\LEAFLET\MICROCAL.CDR\R4\P1\2 CALIBRATION CERTIFICATE MICROCAL is supplied with a detailed internal calibration certificate with traceability to national/international standards. This is supplied free of charge. If a third party calibration certificate is required, it can be supplied at extra cost. Please provide a minimum additional time of 2 months for this. The instrument measures and displays the milliamp input (0 to 19999 µA). Milliamps Source The instrument fuctions as a powered transmitter generating any set current value (0 to 19999 µA) into a load of upto 500 W.
