Safety instructions
Read the operating instructions carefully and especially observe the safety
information. If you do not follow the safety instructions and information on
proper handling in this manual, we assume no liability for any resulting
personal injury or damage to property. Such cases will invalidate the warranty/
guarantee.
a) General information
• The device is not a toy. Keep it out of the reach of children and pets.
• Do not leave the packaging material lying around carelessly. This may become
dangerous playing material for children.
• Protect the appliance from extreme temperatures, direct sunlight, strong jolts,
high humidity, moisture, flammable gases, steam, and solvents.
• Do not place the product under any mechanical stress.
• If it is no longer possible to operate the product safely, take it out of operation and
protect it from any accidental use. Safe operation can no longer be guaranteed
if the product:
- is visibly damaged,
- is no longer working properly,
- has been stored for extended periods in poor ambient conditions, or
- has been subjected to any serious transport-related stress.
• Please handle the product carefully. Jolts, impacts, or a fall, even from a low
height, can cause damage to the product.
• Consult an expert when in doubt about the operation, safety, or connection of
the appliance.
• Maintenance, modifications, and repairs must only be completed by a technician
or an authorised repair centre.
• If you have questions that remain unanswered by these operating instructions,
contact our technical support service or other technical personnel.
Caution:
• To avoid damaging the components, do not attempt to open or repair the product
without professional guidance.
• Alligator clips
• Spare fuse (1 A / 250 V)
• Software and full manual (CD)
• Operating instructions
• The operating range may be affected by environmental factors and nearby
sources of interference.
• Proper use helps to prolong the lifespan of the product.
b) Connected devices
Also observe the safety and operating instructions of any other devices which are
connected to the product.
c) Operation
• Use only the power cord supplied with the product and certified to use in your
country.
• 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.
• 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 the instrument with covers or panels removed.
• Use only the specified type and rating of fuse for this instrument.
• Do not touch exposed junctions and components when the instrument is powered
on.
• If you suspect damage has occurred to the instrument, have it inspected by a
qualified service technician before further use.
• Use the instrument in a well-ventilated area. Inadequate ventilation may cause
an increase of temperature or damage to the device. Ensure good ventilation and
inspect the intake regularly.
• Do not operate in wet conditions. In order to avoid short circuiting to the interior of
the device or an electric shock, do not operate in a humid environment.
• Do not operate in an explosive atmosphere.
• Keep the product surfaces clean and dry.
• Maintenance work must only be performed by qualified technicians.
d) Measurements 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, defined as follows:
Max 10A
fused
Measurement Limits for Main Input Terminals
• 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 as follows for these terminals:
• Input to COM Input Measurement Limit. The measurement limit from the
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 the 10A
input terminal to COM Input terminal is 10 A (DC or AC). The measurement limit
from the μA mA input 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.
e) Measurement Category
Multimeter safety rating:
• 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.
