DT830D Design Review

With the invention of plastic injection moulding, a factory can produce these cases by the thousands for virtually no money. Since automation is involved, it requires little labour and the cost per unit is very small. In my opinion, all plastics should be recyclable; otherwise, it will end up in landfill and eventually poison the Earth. One day we will end up with a plastic planet!

Every country must have the means to recycle all plastics, and tighter regulation on plastic waste. This plastic case does not have any recycling marks or logos, however; I believe a further improvement would be some prominent recycling marks.

The selector switch is usually the most expensive part of a multimeter, and this type of switch assembly is becoming more popular because of the low cost of construction. Interestingly, many high-end meters use the same construction for the switch.

As you can see, there is a plastic tab to secure the LCD. This is of course a good thing as it saves on metal resources by avoiding screws.

The manufacturers have forgotten to make changes to the back cover mould. They are probably using the same one used for the DT830B because it mentions the replacement fuse type, even though, this unit had none.
