Buyer questions

Q: Can DM850 multimeter measure high voltage?
Yes, DM850 is designed to measure both AC and DC voltage. However, it has the maximum voltage limits to be measured. Always check batteries and overload protection before high voltage operation. The device has full overload protection so it is safe to use if you comply with the basic safety rules.

What battery does this multimeter need?
DM850 requires a type 6F22 9V battery that is not included in the package. The battery is sold separately and is a standard type. When the low battery indicator signal appears on the screen, you must change it immediately. The battery usually takes several months for regular use.

Q: Can DM850 be used outdoors and what is the conditions for its resistance?
Yes, the ABS + PC material body is resistant to impact and humidity, so it is suitable for outdoor work. But avoid extreme moisture conditions and do not let it flow with water. Compact design easily fits in pocket or tool bag.
