4.16 Auto Power Off：
1. Whenever the meter is idle for 15mins, it is automatically off and enters
sleep mode. The buzzer will sound before power-off. Press any key to
turn on the power.
2. Press “SELECT” key before turning on the meter. The meter will cancel
power-off function automatically.
5. WARNING
1. When measuring voltage, please ensure that instrument is not connected
or switched to a current or resistance range, or to the diode check.
Always ensure that the correct terminals are used for the type of
measurement to be made.
2. Pay more attention to measure voltage above 36Vdc, especially from
sources where high energy is existed.
3. Avoid making connections to “live” circuits whenever possible.
4. When making current measurements ensure that the circuit is not “live”
before opening it in order to connect the test leads.
5. Before making resistance measurements or diode test, please ensure
that the circuit under test is de-energized.
6. Always ensure that the correct function and range is selected. If in doubt
about the correct range to use, start with the highest and work
downwards.
7. Please pay more attention when using the instrument to conjunction with
a current transformer connected to the terminals if an open circuit occurs.
8. Ensure that the test leads and probes are good condition with no damage
to the insulation.
9. Take care not to exceed the over-load limits as given in the specification.
10. The spec of replacement fuse must be the corrected type and rating.
11. Before opening the case of the instrument to replace battery or fuse,
disconnect the test leads from any external circuit, set the selector switch
to “OFF” position.
6. MAINTENANCE
The meter is a precision instrument. Please don’t change inner circuit without
authorization.
1 Keep the multimeter dry. Keep the multimeter away from dust, dirt, and do
not drop.
2 Multimeter should only be used and stored in normal temperature
environments. Electronic devices’ lives can be shortened under extreme
temperature, and damage batteries, and distort or melt plastic part.
3 Hold the multimeter gently and carefully. Dropping it can damage the circuit
boards and case and can cause the multimeter to work improperly although
the holster can provide enough protection.
4 Wipe the multimeter with a damp cloth occasionally. Do not use harsh
chemicals, cleaning solvents, or strong detergents to clean the multimeter.
5 Take out the battery if the meter will not be used for a long time.
