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.
Check AC power input setting according to the standards in your own country.
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:
The user-replaceable 10 A current-protection fuse is on the front panel. To maintain
protection, replace fuse only with fuse of the specified type and rating. About the
specified type and rating of the fuse, please refer to "7 Current Terminal Fuse" in "Front
Panel Overview" on page 7.
Main Input Terminals (HI Input and LO Input) Measurement Limits
The HI and LO input terminals are used for voltage, resistance, continuity, frequency
(period), capacitance, diode, and temperature test measurements. Two Measurement
Limits are defined for these terminals:
HI Input to LO Input Measurement Limit
The Measurement Limit from HI Input to LO Input is 1000 VDC or 750 VAC, which is
also the maximum voltage measurement. This limit can also be expressed as 1000
Vpk maximum.
LO Input to Ground Measurement Limit
The LO input terminal can safely "float" a maximum of 500 Vpk relative to ground,
where ground is defined as the Protective Earth Conductor in the AC mains power
cord connected to the instrument.
As implied by the above limits, the Measurement Limit for the HI input terminal is a
maximum of 1500 Vpk relative to ground when LO Input is at its maximum of 500 Vpk
relative to ground.
Current Input Terminal (I) Measurement Limits
The Measurement Limit from the current input terminal (I) to the LO Input terminal is 10
A (DC or AC). Note that the current input terminals will always be at approximately the
