GENERAL
FUNCTIONS
MICROCAL is a precision thermometer/calibrator for
measurement of process signals and calibration of process
instrumentation.
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.

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.
