DC type Dynamic Strainmeter DC-96A/DC-97A

This is a dynamic strainmeter that uses direct current as the bridge power supply. 
The bridge power supply can be selected from constant voltage or constant current type. 
In the constant-current type, there is no sensitivity reduction due to the resistance of the connecting cable between the strain gage transducer and the bridge box. 
The instrument can be built into a dedicated case or rack for multi-channel configuration.
