Description

The 3595-1Q1 is an enhanced version of the 3595-1C1, which includes 3 and 4 terminal resistance and RTD measurement facilities organised in a similar way to the original 3595-1H IMP. All 20 channels are available to use in pairs for the 3 and 4 wire measurement modes.

The channels of the 3595-1Q1 are fully programmable and so each 3 or 4 wire measurement takes up2 channels but leaves the rest available for other 3595-1C measurement modes are programmed using the same codes as a 3595-1H. The connector wiring for the 3 and 4 terminal resistance modes differs a little from the 3595-1H, but otherwise, the 3595-1Q is compatible with the measurement modes of the 3595-1H analogue channels.

Features
