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.

Relative value measurement (REL) mode
The relative value mode is a measurement mode that displays the difference between the measured value and
the reference value. Relative value mode is available for most functions of this meter.
1. After pressing the REL button, the measured value currently displayed is saved as a reference value and then the
relative value mode is activated.
2. The “▲” displayed on the LCD screen indicates that the relative value mode has been activated.
3. The value displayed on the screen is the difference between the current measured value and the reference value
saved previously.
4. Press the REL button again to exit the relative value mode.
5. When the measurement function or range changes, the relative value mode will be automatically disabled.
Application of relative value measurement (REL) mode
1. Voltage range: If the LCD display has the initial reading, enable the relative value function; press the REL
button, the LCD screen displays the “▲” symbol, and the initial reading is subtracted; “000” is displayed (Vary
in different ranges), and then perform measurement according to the voltage measurement method.
2. Resistance range: Turn the range to the resistance position; insert the test probes and contact the two metal
probes reliably (short circuit); observe the reading on the LCD, and press the “REL” button if there is an initial
reading; the “▲” symbol appears on the LCD screen. The initial reading is “000” (Vary in different ranges), and
11
then measure the resistance in the method stated.
3. Capacitance range: Turn the range to the capacitance position; insert the test probes and disconnect the two
metal probes; observe the reading on the LCD, and press the “REL” button if there is an initial reading; the “▲”
symbol appears on the LCD screen. The initial reading is “000” (Vary in different ranges), and then measure the
capacitance in the method stated.
Prompt!
• Some ranges are subjected to interference. It is normal that the reading is not reset or changes in a
small range after the relative value measurement is enabled.
• After the measurement is completed, pay attention to the relative value measurement status.
