Velleman DVM851 Problems and Solutions

some common issues and problems with the Velleman DVM851 and their solutions:

Issue: The laser does not turn on. Solution:

  1. Check that the power switch is turned on.
  2. Check that the power cord is properly plugged into the laser and the power outlet.
  3. Check the fuse in the power supply. If the fuse is blown, replace it with a new one.

Issue: The laser is not cutting or engraving as well as it used to. Solution:

  1. Check the laser power setting. Make sure that it is set to a high enough power level for the material you are cutting or engraving.
  2. Clean the laser head. Dust and debris can build up on the laser head and interfere with its performance.
  3. Check the focus of the laser. If the laser is not focused properly, it will not cut or engrave as well.

Issue: The laser cuts or engraves unevenly. Solution:

  1. Check the alignment of the laser head. If the laser head is not aligned properly, it will cut or engrave unevenly.
  2. Check the smoothness of the surface you are cutting or engraving. If the surface is not smooth, it will cause the laser to cut or engrave unevenly.
  3. Check the speed of the laser. If the laser is moving too fast, it will cut or engrave unevenly.

Issue: The laser causes smoke or fumes. Solution:

  1. Use a laser-safe cutting or engraving material. Some materials, such as acrylic, can produce smoke or fumes when they are cut or engraved.
  2. Use a laser ventilation system to remove smoke and fumes from the work area.

PeakTech 1636 Information The PeakTech 1636 is a leakage current clamp for measuring small alternating currents, which can be displayed with a resolution of up to 100 µA. The device measures the current indirectly through the surrounding magnetic field when the jaws enclose the live line (a single cable). Since the sum of all incoming and outgoing currents neutralizes the magnetic field, the leakage current can be measured by enclosing all the cables of a line.
