In some cases, Many different applications involve switching a voltmeter or voltage source n Switching in Multipoint Testing multiple sources and measuring instruments are connected to a single to multiple devices, including testing batteries, electrochemical cells, n Testing Devices with device. Switching allows automating the testing of multiple devices, circuit assemblies, thermocouples, etc. High Voltage and thereby reducing error and costs. The types of switch cards and the techniques used in these applications High Current Designing the switching for an automated test system demands will depend on the magnitude and impedance of the voltages switched. an understanding of the signals to be switched and the tests to be The approximate level for low voltage switching is in the millivolt range performed. Test requirements can change frequently, so automated or less, mid-range levels are from 1V to 200V, and voltages greater than test systems must provide the flexibility
