Universal calibrator built to use in field, for quality assurance, start-up and service technicians, portable with a simple menu navigation on display.
The DIGISTANT® model 4420 universal calibrator, built to use in the field, is ideal for checking and calibrating temperature measurement and control devices. The versatile functions of this portable unit allow to be used on-site or at a fixed location, on the test floor or in the laboratory.
The unit allows the simulation and measurement of voltages, currents, temperatures and resistances.
The automatic ramp function is used for controlling processes.
The universal calibrator measures and simulates 14 models of thermocouples and Pt100. In addition, resistances can be measured from 10mΩ to 2kΩ and simulated from 10Ω to 4kΩ.
The reference junction temperature can be entered manually via keypad; if required, however, an automatic reference to an internal or external point is also possible.
Basic values and the corresponding Δ-values can be stored with 10 freely programmable memories each for voltage, current, temperature and resistance. Relevant values can be added and subtracted by operating the Δ+ and Δ-keys respectively.
