Features w.r.t. strain gauge measurements

• The 1 kHz carrier frequency for strain gauge measurements ensures noise insensitive measurements with high reproducability, even under severe conditions.
• Supports all types of bridge configurations and connections, e.g. straingauges ¼-bridge in 3- and 4-wire connection. Internal ¼-bridge completion with the choice of 120, 240 or 350 Ohm
• Concept of 1-5 common dummies for 100 channels. The advantage of a common dummy straingauge is the compensation of the temperature dependent strain in the measured object. This strongly simplifies the application and wiring.
• -An optional central isolation and resistance module is available. This option is very useful when the straingauges can not be accessed during the test (e.g. if they are under water).
