11. If the meter works improperly, do not use it. The protection
measures of the meter may have failed. If in doubt, send
the meter for repair.
12. Do not store or use the meter in an environment of high
temperature, humidity, inflammable, explosive and strong
magnetic field.
13. When using the probes, keep your fingers behind the
finger guards.
14. Do not use the low-pass filter to verify hazardous voltage,
for there may be a voltage over the indicated value. First,
measure the voltage to check whether it is hazardous in the
case of not connecting a filter, then select low-pass filtering.
15. Before testing resistance, continuity, conductance, diode
or capacitor, shut off the power to the circuit and discharge
all high-voltage capacitors.
16. Before measuring the current, check the fuses of the meter.
17. Do not measure the voltage or current higher than the
allowed input values. When the range of measured values
cannot be determined, set the functional range switch at
the maximum-range position.
18. When the symbol "cCJl" shows on the LCD display, the
battery should be promptly charged to ensure measurement
accuracy.
19. Do not arbitrarily change the wiring within the meter to
avoid damaging the meter and endangering the safety.
20. Soft cloth and mild detergent should be used to clean the
surface of the meter when servicing. No abrasive and
solvent should be used to prevent the surface of the meter
from corrosion, damage and accident.
21.To test the known voltage before use to confirm the
product function is correct.
22. If you want to replace the test lead, you need to replace
it with a test lead of the same or higher grade of CAT Ill
1000V/CAT IV 600V.

When the meter detects the voltage ?30V or overload (0L),
the symbol ".&. "will display as a warning for potential
hazardous voltage.
