General Safety Requirements
Before any operations, please read the following safety precautions to avoid any
possible bodily injury and prevent this product or any other products connected from
damage. In order to avoid any contingent danger, this product is only used within the
range specified.
◼Use Proper Power Cord. Use only the power cord supplied with the product and
certified to use in your country.
◼Product Grounded. This instrument is grounded through the power cord grounding
conductor. To avoid electric shock, the grounding conductor must be grounded. The
product must be grounded properly before any connection with its input or output
terminal.
◼Limit operation to the specified measurement category, voltage, or amperage
ratings.
◼Check all Terminal Ratings. To avoid instrument damage and the risk of electric shock,
check all the Measurement Limits and markers of this product. Refer to the user's
manual for the Measurement Limits before connecting to the instrument. Do not
exceed any of the Measurement Limits defined in the following section.
◼Do not operate without covers. Do not operate the instrument with covers or panels
removed.
◼Use Proper Fuse. Use only the specified type and rating fuse for this instrument.
◼Avoid exposed circuit. Do not touch exposed junctions and components when the
instrument is powered.
◼Do not operate if in any doubt. If you suspect damage occurs to the instrument,
have it inspected by qualified service personnel before further operations.
◼Use your instrument in a well-ventilated area. Inadequate ventilation may cause
increasing of temperature or damages to the device. Please keep well ventilated and
inspect the intake regularly.
◼Do not operate in wet conditions. In order to avoid short circuiting to the interior of
the device or electric shock, please do not operate in a humid environment.
◼Do not operate in an explosive atmosphere.
◼Keep product surfaces clean and dry.
◼Only the qualified technicians can implement the maintenance.

Measurement Limits
The protection circuitry of the multimeter can prevent damage to the instrument and
protect against the danger of electric shock, when the Measurement Limits are not
exceeded. To ensure safe operation of the instrument, do not exceed the Measurement
Limits shown on the front panel, it is defined as follows:
Main Input Terminals Measurement Limits
The Input and COM Input terminals are used for voltage, resistance,
continuity, frequency (period), capacitance, diode, and temperature test measurements.
The Measurement Limit is defined for these terminals:
Input to COM Input Measurement Limit
The measurement limit from Input to COM Input is 1000 VDC or 750
VAC, which is also the maximum voltage measurement. This limit can also be
expressed as 1000 Vpk maximum.
Current Input Terminal Measurement Limits
The measurement limit from 10A input terminal to COM Input terminal is 10 A (DC or
AC).
The measurement limit from μA mAinput terminal to COM Input terminal is 600 mA
(DC or AC).
Note that the current input terminals will always be at approximately the same voltage as
the COM Input terminal.
Measurement Category
The safety rating of the multimeter:
1000 V, CAT I
IEC Measurement Category I. The maximum measurable voltage is 1000 Vpk in the HI -LO
terminal.
600 V, CAT II
IEC Measurement Category II. Inputs may be connected to AC mains power (up to 600
VAC) under Category II overvoltage conditions.
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.

General Inspection
After you get a new multimeter, it is recommended that you should 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 our distributor responsible for this service or our local offices.
3. Check the Complete Instrument
If it is found that there is damage to the appearance of the instrument, or the
instrument cannot work normally, or fails in the performance test, please get in
touch with our distributor responsible for this business or our local offices. If there is
damage to the instrument caused by the transportation, please keep the package.
With the transportation department or our distributor responsible for this business
informed about it, a repairing or replacement of the instrument will be arranged by
us.
