The Model 2790-A, which is similar to the Model 2790-H, enables high voltage ohms measurements down to 1MΩ.
With the addition of a Model 7702 40-channel differential multiplexer module (part of the Integra family of switch/measure solutions), the Model 2790-A + Model 7702 opens the door to higher channel count applications, such as hi-pot/continuity testing of connectors, harnesses, and power distribution devices up to 500V (internally sourced) up to 40 channels.
