12. according to the user command. In course of executing, the input of the switch can be by the keyboard and serial interface.





6. Instruction:
Through the stimulating voltage interface of load cell which connect to the LDO manostat and the precise resistance network. The manostat produce the stable voltage for the work of the circuitry. The reference voltage of precise resistance network is sent to the D/A diversion for basic voltage by the voltage select switch. Under the control of the SCM,the D/A diversion output the relative stimulating voltage to the resistance network. The output voltage of simulator is transmitted by the load cell interface after the diverse of the resistance network. The temperature load cell offer the temperature compensation data for the temperature amend. The A/D diversion of the SCM measures the data of the stimulating voltage. The position of voltage select switch is sent to the SCM by the I/O interface. The SCM checks whether the position of voltage select switch and the current stimulating voltage match. The SCM communicates with the upper-machine through the RS-232 interface. The operator controls the simulator by keyboard. The memorizer is used to save the program input by keyboard or loaded down through RS-232 interface.
