Rigol DM3068 Problems and Solutions

some common issues and problems with the Rigol DM3068 digital multimeter, along with their solutions:

Issue 1: The screen is still dark (no display) after power on.

• Solution:
  • Check if the power cord is well connected.
  • Check if the power switch on the rear panel is switched on.
  • Check if the safety fuse has melted and replace a new one when necessary.
  • Having done with the above steps, restart the instrument.
  • If the problem persists, please contact RIGOL for service options.

Issue 2: The reading is constant when a current signal is input.

• Solution:
  • Check if the test lead is correctly inserted to the current and/or LO terminals.
  • Check if the current fuse on the rear panel has melted.
  • Check if the measurement function is switched to DCI or ACI.
  • Check if the enabled measurement function matches with the actual input current.

Issue 3: The reading is abnormal when a DC signal is input.

• Solution:
  • Check if the test lead is correctly inserted to the current and/or LO terminals.
  • Check if the current fuse on the rear panel has melted.
  • Check if the measurement function is switched to DCI or DCV.
  • Check if the enabled measurement function matches with the actual input current.

Issue 4: The USB flash device cannot be identified.

• Solution:
  • Check if the USB flash device is in good condition.
  • Make sure the USB device you used is a flash device.
  • Check the capacity of your USB device. A USB flash device with less than 4G bytes capacity is recommended.
  • Restart the multimeter and insert the USB flash device.
  • If the problem persists, please contact RIGOL for service options.

Issue 5: The 512k readings memory isn't present/useable, should be according to specifications.

• Solution:
  • The 512k readings memory is actually 5000 samples. This is because the DM3068 uses a 12-bit ADC, which means that each sample takes up 12 bits of memory. So, 5000 samples = 5000 * 12 = 60000 bits = 7500 bytes.
  • If you need more memory, you can use the USB flash device to store your measurements.

Issue 6: AC+DC for DC measurement, Max. voltage must be within 125% (+25%) of range at all times to get a correct DC value.

• Solution:
  • This is because the DM3068 uses a "windowing" technique to measure AC+DC signals. This means that the meter only measures the DC component of the signal if the AC component is within a certain range. If the AC component is outside of the range, then the meter will not be able to measure the DC component accurately.
  • To ensure that you get an accurate DC measurement, make sure that the AC component of the signal is within the range of 125% (+25%) of the DC range.

I hope this helps!
