DT830B Digital Multimeter

Description:
The DT830B is a Digital Multimeter that can measure AC and DC voltage, DC current, and resistance. It has diode and transistor test functions as well. It is a compact pocket-sized 3½ digit meter and one of the cheapest currently available on eBay. The photographs and circuit diagram in this article may be of interest to engineers who need to repair their meters.
This meter has Chip on Board (COB) package inside, and the 830 designation leads me to believe that this meter has the Intersil ICL7106 single chip solution, or perhaps a variant of that design. This meter is very similar to the Mastech M-830B Multimeter that I reviewed earlier, except this one produces an HV symbol on the Liquid Crystal Display (LCD).
This is an affordable pocket meter that works reasonably well for the price.
This meter operates on a standard 9 V (NEDA 1604 6F22) type battery.
