2.1.2 DC voltage ratio measurement

Basic Information
Ratio measurement refers to that measure input voltages to main input terminal and sense

terminal with multimeter, and work out the ratio.
Voltage ratio= Voltage value of main input terminal/Voltage value of sense terminal.
Main input LO terminal and sense LO terminal have to share common reference points, and

their voltage difference can not exceed ±2V.
Ration measurement is automatic measurement range measurement, and automatic zero

calibration is started. Main input terminal can measure up to 1000V voltage at most, and
sense terminal to 12V voltage at most.
