CURRENT MODES

The MTS-1710 has seven basic current modes, which determine how the internal current amplifiers are
configured to perform different types of testing.

The current mode is selected by the [CURRENT MODE] selector. The chart on the next page is a quick
reference for selection of the proper mode. Each of the current modes is detailed in the following sections:
