Function: Fast sampling 2,5 Msps, 1 MHz analog band (limited do oscilloscope with ACV file), 4000 codes, excellent performance. One-button video, three waveform scanning modes are available: automatic/normal/single. Data waveform storage function, can store 100 data groups, 10 waveforms, can record data better. Multimeter functions include DC/AC voltage/current, resistance, capacitance, frequency, duty cycle, test diodes/continuity. Automatic/manual range switching, real-time data and saved data are displayed on the same screen, easy to operate, and test data is displayed clearly.

DIGITAL METER MULTIMETER CURRENT LCD OSCILLOSCOPE List of packages: 1 x oscilloscope multimeter (battery not included) 2 x measuring cable 1 x Manual 1 x Tool Bag Check the case before use. Do not use a meter with a damaged housing. Check for ma or missing plastic parts. Particular attention should be paid to the insulation layer of measuring wires and connecting wires. Do not touch the metal part of the measuring wire probe with your fingers when using the measuring wire. Do not use in high temperature, humidity, rain, flammable and explosive environment, and the instrument is wet. Never apply do a voltage/current meter exceeding the maximum limit that the meter can withstand. 1. Turn the knob to select the measuring gear to turn on the meter power. Turn the knob to select and the OFF gear will turn off the power. 2. If you do not press the button + knob at the set time, the meter will automatically go to sleep. To turn off the automatic sleep function, you can press and hold the “F1” key, then turn the knob, and when turned on, you can automatically set continuous operation.
