4. When changing measuring function, please make sure the probe of test leads is taken away from the test point
before plugging in/out the plug of test leads and before switching on/off the device.
5. Pay attention to the safety warning signal displayed on the instrument: When the measured voltage exceeds the
"safety voltage" (24VDC/AC), a warning information “
”is displayed to remind you;
6. When the voltage to earth on the reference end "COM" of the instrument reaches 500V, please do not make
voltage measurement;
7. Please do not make AC current measurement of circuits with a voltage of over AC 250V;
8. When measuring functions are pointed at the gears of current, resistance, continuity test, diode, capacitance
and ℃ etc., never bridge the test leads over the two ends of the probe of voltage;
9. Before the test of resistance, diode/continuity test, the power of the equipment to be tested must be cut off and
make sure the capacitor of the circuit has been fully discharged;
10. Before opening the back cover of instrument for replacement of protective tube, the power of the instrument
must be turned off and the test lead should be kept away from the circuit to be tested; protective tube of the
same specification must be used for replacement;
11.
Do not alter or dismantle the product or its accessories or use them for purposes other than the purpose for
