GENERAL
RADICAL is a precision thermometer/calibrator for measurement of process signals and calibration of process
instruments.
RADICAL is a microcontroller based design. It incorporates a highly stable reference, a high-resolution
Analog - to - Digital converter, electronic switching circuitry & other specialised electronics.
Further, use of the micro-controller allows direct display in ºC/ºF of thermocouple and RTD inputs, as well as
automatic and manual cold-junction compensation for thermocouples.

Bar-Graph display
Min-Max function
Step function (manual) in Source mode
Ramp function in Source mode
Auto shutoff
Battery low warnings
Gives a graphic indication of the measured parameters on a
scale of 0~100% in steps of 2.5%
Shows ‘peak’ & ‘trough’ values over a measurement interval
Allows a sourced parameter to be increased or decreased
in steps of 1 mV, 1 mA or 1Ω
Allows a sourced parameter to be smoothly increased or
decreased at a specified rate
Switches the instruments off if no key is pressed for the
specified time
Gives visual alerts when the battery is low and needs
recharging, & also when it is about to shut down
