The Model 3800 Wide Range Strain Indicator is a versatile, high-precision laboratory-type instrument designed for use with strain gages and strain gage based transducers. Principal features of the Model 3800 are wide-range control of gage factor; excitation precisely settable over 1 - 15 volt range; and wide balance range with no bridge loading effect.
With these extended operating capabilities, the Model 3800 can be used for the most demanding measurement tasks which are not possible with conventional strain measuring instruments and general-purpose transducer indicators. Resolutions achievable with the Model 3800 are 0.10µ when used as a strain indicator, and 0.10µV/V when used as a transducer indicator (0.025µV/V with suppressed zero).
In addition to the wide-range features, the Model 3800 incorporates simplified operating controls that minimize set-up time, and promote measurement accuracy. The operator follows a logical sequence of steps to configure the instrument for the desired measurement. Color-coded interlocked push-button controls minimize operator errors, and make the operating mode instantly recognizable.
