Velleman HPS140MK2 Problems and Solutions
The Velleman HPS140MK2 is a popular hot plate stirrer that is used in a variety of laboratory applications. However, like any piece of equipment, it can experience some common issues. Here are a few of the most common problems and solutions, as provided by experts:
- The hot plate won't turn on. This is usually caused by a blown fuse or a faulty power cord. To check the fuse, look for a small glass tube with two metal prongs inside. If the glass is blackened or the prongs are fused together, the fuse is blown and needs to be replaced. To check the power cord, unplug it from the wall outlet and inspect the cord for any damage. If the cord is frayed or cracked, it will need to be replaced.
- The hot plate doesn't heat up evenly. This is usually caused by a dirty heating element. To clean the heating element, unplug the hot plate from the wall outlet and allow it to cool completely. Then, use a soft cloth dampened with isopropyl alcohol to wipe down the heating element. Be sure to dry the heating element thoroughly before plugging the hot plate back in.
- The hot plate makes a humming noise. This is usually caused by a loose or worn-out fan bearing. To fix the noise, you will need to open the hot plate and access the fan bearing. Once you have access to the bearing, apply a small amount of lubricant to the bearing. If the noise persists, you may need to replace the fan bearing.
If you are experiencing any of these problems with your Velleman HPS140MK2, it is important to troubleshoot the issue and fix it as soon as possible. If you are unable to fix the problem yourself, you should contact Velleman customer support for assistance.
