RS232 Data Interface
The instrument can transmit data to PC computer by a RS232 infrared photoelectricity interface in real-time mode. You can connect the RS232 interface to a serial port of PC computer, then install the user data record software into the computer according to the README.TEXT file in the SETUP disk. After that, you can record and print the measured data of the instrument in real-time mode on the WINDOWS. The user data record special software can complete to record, collate, plot, print data in real-time mode.
 
Note: In all measurement mode, the measured data can be transmitted to the PC serial port automatically, but the
instrument will stop transmitting in the SETUP mode.
