Safety instructions
The MT8206 digital graphical multimeter is designed in accordance with the requirements for the over-voltage
category of CAT II-1000V and CAT III-600V and level 1 pollution protection in IEC1010-1 safety specification.
1. Check the case before use. Do not use the device with damaged case; check for cracks or missing plastic parts.
Check the insulation of the probe and connecting wires. Do not touch the metal part of the probe when using it;
2. Do not operate it in high temperature, humidity, rain and flammable and explosive environment or when the
instrument is wet;
3. Never measure the voltage/current beyond its maximum limits;

4. When changing the measurement function, before inserting the probe plug and turning on and off the
multimeter, be sure to remove the probe from the test point;
5. Pay attention to the safety Warning signal displayed by the meter. When the measured voltage exceeds
DC1000V or AC750V, the buzzer will give long alarm; when the voltage range of DC1000V and AC750V
exceeds the safe voltage (24V), the buzzer will sound three times and the high voltage sign will be displayed
to alert the operator for safety;
6. When the voltage to the ground on the reference input “COM” of the meter is 500V, do not measure voltage
measurement;
7. Although the probe 10A range is connected with a 250V fuse, it is very dangerous to measure the voltage
incorrectly, which may damage the instrument;
8. When the current, resistance, continuity test, diode, capacitor and other positions are selected, never connect the
probe to both terminals of the voltage source;
9. Before performing resistance and diode/continuity tests, turn off the power to the device under test and
discharge the capacitor in the circuit.
10. Before opening the back cover to replace the fuse, turn off the power supply and disconnect the probe from the
circuit under test; replace the fuse with the same specifications;
11. Do not modify, disassemble or use the products and accessories for any purpose other than the design purpose
of the product. Do not replace parts and accessories at will;
12. Do not charge the battery. Replace the battery in time when the low voltage symbol is displayed on the
screen.

Safety signs
Caution! Danger! When this sign is found near other symbols or jack terminals, the users are
prompted to follow the instructions in this manual to prevent instrument damage/personal injury.
Caution! Electric shock! The presence of this sign near one or more terminals indicates that these
terminals may carry dangerous voltages during use. For the sake of safety, do not touch the test
probes of the probes when the terminals are energized.
This sign found near the terminal block indicates that the maximum withstand current between the
terminal and COM is 10A.
FUSE indicates a built-in 10A (or 500mA) fuse; current measurement is not allowed on circuits with
voltage of AC 250V or higher.
Prompt!
The prompt states that special care should be taken during operation. Incorrect operation can result in
erroneous measurement results or damage to parts.
Attention!
The attention states that care must be taken during operation in case of damage to this product and
other property.
Warning!
The Warning states that the operators should concentrate on the operation. Errors or violations may
result in personal injury or even life risk.

Basic Operation
Power on/off
Turn the knob to the desired measurement position to turn the multimeter on. Turn the knob to the "OFF"
position again to turn off the power.
Attention!
• Move the test probe away from the test point before turning the knob (shutdown).
• When the meter is used, turn off the power in time.
Automatic shut-down
If there is no button operation within the set 15 minutes, the meter will automatically shut down.
Tips
• Only the display of the main chip and LCD screen is turned off when the instrument is
automatically shut down, but there is still a certain leakage current.
• If it is not used for a long time, switch the knob to “OFF” position
Battery replacement
When the meter is in use and the low-voltage symbol appears in the upper right corner of the LCD screen,
the user should replace the battery as soon as possible.
When the meter is not used for a long time, take out the battery to prevent the battery from leaking and
damaging the meter.
Warning!
Pay attention to the safety of the battery.
