1. Safety Information
Safety Considerations
Before any operations, please read the following safety precautions to avoid any
possible bodily injury and prevent damage to this product or any other products
connected. To avoid any contingent danger, use this product only as specified.
EC Declaration of Conformity:
Meets intent of Directive 2004/108/EC for Electromagnetic Compatibility.
Limit operation to the specified measurement category, voltage, or amperage ratings.
Do not use the multimeter if it is damaged. Before you use the multimeter, inspect
the case. Look for cracks or missing plastic. Pay particular attention to the insulation
surrounding the connectors.
Do not use the test leads provided for other products. Use only the certified test
leads specified for this product.
Inspect the test leads for damaged insulation or exposed metal.
Before use, verify the multimeter's operation by measuring a known voltage.
Only the qualified technicians can implement the maintenance.
Always use the specified battery type. The power for the multimeter is supplied with
two standard AA 1.5 V batteries. Observe the correct polarity markings before you
insert the batteries to ensure proper insertion of the batteries in the multimeter.
Check all Terminal Ratings. To avoid fire or shock hazard, check all ratings and
markers of this product. Refer to the user's manual for more information about
ratings before connecting to the multimeter.
Do not operate the multimeter with the cover or portions of the cover removed or
loosened.
Use Proper Fuse. Use only the specified type and rating fuse for the multimeter.
Do not operate if in any doubt. If you suspect damage occurs to the multimeter,
have it inspected by qualified service personnel before further operations.
To avoid electric shock, do not operate this product in wet or damp conditions.
Do not operate in an explosive atmosphere.
Keep product surfaces clean and dry.
Do not apply more than the rated voltage (as marked on the multimeter) between
terminals, or between terminal and earth ground.
When measuring current, turn off the circuit power before connecting the
multimeter in the circuit. Remember to place the multimeter in series with the
circuit.

1.Safety Information
When servicing the multimeter, use only the specified replacement parts.
Use caution when working above 60 V DC, 30 V AC RMS, or 42.4 V peak. Such
voltages pose a shock hazard.
When using the test leads, keep your fingers behind the finger guards on the test
leads.
Remove the test leads from the multimeter before you open the battery cover.
To avoid false readings, which may lead to possible electric shock or personal injury,
replace the battery as soon as the low battery indicator appears and flashes.
Disconnect circuit power and discharge all high-voltage capacitors before testing
resistance, continuity, diodes, or capacitance.
Use the proper terminals, function, and range for your measurements.When the
range of the value to be measured is unknown, set the rotary switch position as the
highest range, or choose the auto ranging mode. To avoid damages to the multimeter,
do not exceed the maximum limits of the input values shown in the technical
specification tables.
Connect the common test lead before you connect the live test lead. When you
disconnect the leads, disconnect the live test lead first.
Before changing functions, disconnect the test leads from the circuit under test.

1.Safety Information
Measurement Category
The multimeter has a safety rating of 600 V, CAT III.
Measurement category definition
Measurement CAT I applies to measurements performed on circuits not directly
connected to the AC mains. Examples are measurements on circuits not derived from the
AC mains and specially protected (internal) mains- derived circuits.
Measurement CAT II applies to protect against transients from energy-consuming
equipment supplied from the fixed installation, such as TVs, PCs, portable tools, and
other household circuits.
Measurement CAT III applies to protect against transients in equipment in fixed
equipment installations, such as distribution panels, feeders and short branch circuits,
and lighting systems in large buildings.
Measurement CAT IV applies to measurements performed at the source of the low-
voltage installation. Examples are electricity meters and measurements on primary over
current protection devices and ripple control units.

2.Quick Start
2. Quick Start
General Inspection
After you get a new multimeter, make a check on the instrument according to the
following steps:
1. Check whether there is any damage caused by transportation.
If it is found that the packaging carton or the foamed plastic protection cushion has
suffered serious damage, do not throw it away first till the complete device and its
accessories succeed in the electrical and mechanical property tests.
2. Check the Accessories
The supplied accessories have been already described in the Appendix A: Enclosure
of this Manual. You can check whether there is any loss of accessories with reference
to this description. If it is found that there is any accessory lost or damaged, please
get in touch with the distributor of OWON responsible for this service or the
OWON's local offices.
3. Check the Complete Instrument
If it is found that there is damage to the appearance of the instrument, or the
instrument can not work normally, or fails in the performance test, please get in
touch with the OWON's distributor responsible for this business or the OWON's local
offices. If there is damage to the instrument caused by the transportation, please
keep the package. With the transportation department or the OWON's distributor
responsible for this business informed about it, a repairing or replacement of the
instrument will be arranged by the OWON.
Install the Batteries
The multimeter is powered by two 1.5 V AA alkaline batteries.
Warning:
To avoid false readings, which could lead to possible electric shock
or personal injury, replace the battery as soon as the low battery
indicator appears.
Before replacing the battery, turn off the meter,
disconnect test
leads and any connectors from any circuit under test, remove test
leads from the input terminals. Use only the specified battery type.
Use the following procedure to install the batteries.
(1) Ensure that the rotary switch is at the position. Remove test leads and any
connectors from the input terminals.
