IOC 502-t is a calibrator multimeter for generating currents 0/4-22mA in source or sink mode and voltages from 0-14V. At the same time, external voltages in the ranges of ±2V, ±20V and ±200VDC (fixed ranges or automatic range selection) and currents up to ±100mA can be measured and shown on the display. mV voltages of 0-28mV or 0-560mV can be generated for calibrating strain gauge amplifiers, measuring transducers and small-signal devices.

DIN thermocouples J, K, N, R, S, T, B, E are simulated. The desired sensor type is selected and the temperature value entered via the keyboard. The temperature appears on the display and the mV signal is available at the output jacks. The connection point is compensated for the ambient temperature. Compensation can also be switched off.

The device is powered by an internal rechargeable Li-Ion battery and allows 9 hours of continuous operation with 20mA current output and backlight off.
