The TINYCAL series instruments offer a dual function: generation/simulation and measurement. The instrument’s keypad allows its configuration for the generation of fixed values, both in engineering and percentage values. The keypad also allows the generation by jumps as well as the configuration of the jump time between 1 and 9 seconds for each section, for which the instrument is provided with 6 keys to store the configuration values. The simulation from the instrument – T240 and T250 – offers the possibility to configure it to simulate the response of the sensor (Pt100 or type of thermocouple selected).
The measurement function, which is easily selectable by means of the IN/OUT key and whose characteristic is clearly indicated on the instrument display, allows the indication of the value to be measured. The measuring circuit is protected against short-circuits and external voltages up to 30 V, thus ensuring a longer service life of the instrument. The T220 and T225 models of the TINYCAL family are equipped with an integral 24 Vdc power supply, which allows, by means of the appropriate connection, the loop to be powered from the calibrator itself (active mode) or voluntarily to work in passive mode.
All the instruments of the TINYCAL family offer great precision and high resolution, which together with their ease of use, great reliability and ease of transport, due to their reduced weight and dimensions, make these instruments basic standards in the instrumentation workshop.
