Page 53: Operation Mode "Device Test" With Strain
Operation mode "Device Test" with strain gauge simulator Note: The "Device Test" function is only included in the TRANS CAL model 7281-V0001 version. The most accurate way to calibrate a measurement chain is a comparison with a high-precision reference. A mechanical quantity whose precise value is known is applied as a load to the sensor. The effect, for instance for strain gauge based sensors, is to unbalance the bridge circuit, resulting in an output signal. -
Page 54: Operation Mode "Voltage Source
