DIGITAL MULTIMETER OPERATION MANUAL
1. General
The instrument is a pocket digital multimeter, which is used to measure DCV, ACV, and DCA, resistance, diode and continuity
test. It is an ideal tool for labs, household and wireless enthusiasts.
2. Safety Notes
1. Do not input a limit value over the range when measuring.
2. When measuring voltage higher than 36V DCV, 25V ACV, check the connection and insulation of the test leads to avoid
electric shock.
3. Keep the test leads away from the testing point when converting function and range.
4. Don’t add voltage to the input terminal when measuring resistance.
