Highland Technology has announced the latest release in its line of standalone test and measurement modules, the P620 Resistance Simulator. The P620 includes six independent, isolated channels that can simulate platinum RTDs and resistances ranging from 5 ohms to 5Mohms. It uses entirely solid-state simulation to eliminate transient errors associated with relay switching and provides for monotonic resistance changes.
Any channel may be rerouted, under software control, to the front-panel calibration-check connector, allowing the board to be tested for calibration by a precision DVM without disturbing the connections to the equipment under test. The built-in self test provides an onboard ohmmeter, allowing loopback checking and full automatic self-test. Both USB and Ethernet interfaces are provided.
