When broadband strain signal conditioner 1B31's pin 19 connects to pin 20, the excitation voltage output by programmable bridge excitation source UEXC = +10 V. In order to upgrade UEXC to +10 ~ +15 V, it must be connected to a resistor REXT between the XC ADJ end and SENSE- end, the circuit is shown in the figure. REXT value is determined by the following formula ( resistance units kΩ):
