All Tinycal series instruments are dual function: generation/simulation and measurement. Keys on the instrument’s front panel enable configuration for generation of set values in either engineering units or percentages. Panel keys also enable generation in steps that can be timed for 1 to 9 seconds per step, which it memorizes thanks to its 6 configuration keys. Simulation from the instrument —T240 and T250— can be configurated to simulate the sensor response (Pt100 or type of thermocouple selected).

The measurement function is easily selectable with the IN/OUT button, as clearly indicated on the display, which indicates the value to be measured. To prevent possible connection or manipulation errors, the measurement circuit is protected againstshort-circuits and external voltage up to 30 V, guaranteeing the instrument longer service life. The T220 and T225 models of Tinycal family are equiped with an integrated 24-V dc sypply, enabling power supply to the loop from the calibrator (active mode), or volontarily in passive mode.

All the instruments of the Tinycal family offer high precision and high-resolution measurements, which, together with their ease of use, high reliability and convenient transport, as well as reduced weight and small size, make them basic standards in an instrumentation workshop.
