Frequently Asked Questions - DM3068 Rigol
What is the maximum input voltage for the Rigol DM3068?
The DM3068 is rated for CAT I 1000V and CAT II 600V. For DC voltage, the maximum is 1000V; for AC RMS, it is 1000V up to 1 kHz, derating at higher frequencies.
Can the DM3068 measure capacitance?
Yes, the DM3068 can measure capacitance from 1 nF to 10 mF with a resolution of 1 pF.
How do I connect the DM3068 to a computer?
The DM3068 has a USB device port for connection to a PC. You can also install an optional GPIB or LAN interface module.
What is the accuracy of the DM3068?
The DM3068 offers up to 0.02% DC voltage accuracy (1-year) and 0.06% AC voltage accuracy (1-year), depending on range and frequency.
Does the DM3068 support data logging?
Yes, the DM3068 has a data logging function that can record measurements with user-defined intervals. Logged data can be stored internally or transferred via USB.
How do I perform a diode test?
Set the function dial to the diode symbol. Connect the red lead to the anode and black to the cathode. The multimeter displays the forward voltage drop in volts.
What type of fuse does the DM3068 use?
The DM3068 uses a 3.15A/250V fast-acting fuse for the current measurement input. Always replace with the same type and rating.
Can I measure AC current with the DM3068?
Yes, the DM3068 can measure AC current from 1 μA to 10 A (with internal shunt) and up to 10 A RMS. For higher currents, use an external current clamp.
How do I clean the DM3068?
Clean the exterior with a soft, dry cloth. Do not use any liquids or solvents. Avoid getting moisture inside the device. No internal cleaning is required.
What is the warranty period for the DM3068?
Rigol typically provides a 3-year warranty for the DM3068 digital multimeter, covering manufacturing defects under normal use.
