RIGOL
Service Guide for DM3000 Series
Rear panel multiplexer function (only for the model equipped with multiplexer module)
Including the model of multiplexer card, the voltage limit of LO relative to safe ground
falls to 200Vpeak (Max).
Channel: 12 voltages, 4 current, additional protections.
Measurement Type：2-wire resistance, capacitance, DC voltage, DC current, AC voltage, AC
current, period, diode and frequency.
Work Characteristics：The precision of performance is consistent with the value measured from
front panel. The switch time of multiplexer card is 50ms; the switch time of auto measurement is
600ms. (4½ digits)
Input Characteristic: Difference input voltage is 150Vpeak(Max); the isolated voltage in
interchannel is 150Vpeak(Max)，the current terminal is input 1Apeak(Max), channel isolation > 60dB
(@10KHz)，the voltage of all the terminal relative to safe ground is 150Vpeak(Max).
Input Protection: 2A restore the fuse in current channel, 250V limit voltage.
500mA melt the fuse in voltage channel with multiplexer card.
