Frequently Asked Questions - DM858 Rigol
How do I measure DC voltage?
Set the rotary switch to DCV, connect the test leads (red to V/Ω, black to COM), and probe the circuit. Read the voltage on the display.
How do I measure AC voltage?
Set the rotary switch to ACV, connect the test leads (red to V/Ω, black to COM), and probe the circuit. The meter displays the RMS voltage.
How do I measure resistance?
Turn off power to the circuit, set the rotary switch to Ω, connect the test leads across the component, and read the resistance value.
How do I use the continuity test?
Set the rotary switch to the diode/continuity position (≥ symbol), connect the test leads across the points to test. A beep indicates continuity (resistance < 50Ω).
How do I measure current?
Select DCI or ACI on the rotary switch. Insert the red lead into the A or mA terminal (depending on expected current), break the circuit, and connect the meter in series.
How do I clean the multimeter?
Disconnect all test leads and power. Use a damp cloth with mild detergent to wipe the exterior. Do not use solvents or immerse the meter.
How do I replace a fuse?
Turn off and disconnect the meter. Open the battery/fuse compartment. Remove the blown fuse and replace with same type (1A/1000V or 10A/1000V). Close the compartment.
What is the maximum input voltage?
For voltage measurements, the maximum input is 1000V DC or 750V AC RMS. For current, do not exceed 10A.
How do I connect to a PC?
Use the USB port on the back. Install the UltraSigma software from the included CD or Rigol's website. Connect the meter and configure the interface settings.
What is the warranty period?
The Rigol DM858 comes with a 3-year warranty against defects in materials and workmanship. Register your product online for full coverage.
