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.

Special Features & Functions

24 V loop supply To power 2-wire transmitter without using external supply

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
