Before changing functions or measuring range, disconnect the test leads
from the circuit under test.
For all DC functions, to avoid the risk of shock due to possible improper
readings, verify the presence of any AC voltages first by using the
AC function. Then select a DC voltage range equal to or greater than
the AC range.
Use 2 x 1.5 V AAA type batteries, properly installed in the meter‟s
battery case, to power the meter.
Replace the battery as soon as the battery indicator appears. With
a low battery, the meter may produce false readings that can lead to
electric shock and personal injury.
Do not operate the meter with the case (or part of the case) removed.
Always verify that all connections are reliable and safe.
Avoid body contact with ground potential (e.g. metallic terminals,
output sockets, lead clamp…) while measuring. Make sure to be
electrically insulated from ground during measurement.
4. Overvoltage/Installation Category
DMMs are categorized depending on the risk and severity of transient
overvoltage that might occur at the point of test. Transients are short-lived
bursts of energy induced in a system, e.g. caused by lightning strike on a
power line.
The existing categories according EN 61010-1 are:
CAT I
A CAT I-rated meter is suitable for measurements on protected
electronic circuits that are not directly connected to mains power,
e.g. electronics circuits, control signals…
CAT II
A CAT II-rated meter is suitable for measurements in CAT I
environments and mono-phase appliances that are connected to
the mains by means of a plug and circuits in a normal domestic
environment, provided that the circuit is at least 33 ft (10 m) apart
from a CAT III, or 66 ft (20 m) apart from a CAT IV environment.
E.g. household appliances, portable tools…
CAT III
A CAT III-rated meter is suitable for measurements in CAT I and
CAT II environments, as well as for measurements on (fixed)
mono- or poly-phased appliances which are at least 33 ft (10 m)
apart from a CAT IV environment, and for measurements in or on
distribution level equipment (fuse boxes, lighting circuits, electric
ovens).
CAT IV
A CAT IV-rated meter is suitable for measuring in CAT I, CAT II
and CAT III environments as well as on the primary supply level.
Note that for all measurements on equipment for which the supply
cables run outdoors (either overhead or underground) a CAT IV
meter must be used.

5. Pollution Degree
IEC 61010-1 specifies different types of pollution environments, for which
different protective measures are necessary to ensure safety. Harsher
environments require more protection, and the protection against the
pollution which is to be found in a certain environment depends mainly on
the insulation and the enclosure properties. The pollution degree rating of
the DMM indicates in which environment the device may be used.
Pollution
degree 1
No pollution or only dry, nonconductive pollution occurs. The
pollution has no influence (only to be found in hermetically
sealed enclosures).

DVM630
V. 01 –22/04/2013 8 ©Velleman Inc.
Pollution
degree 2
Only nonconductive pollution occurs. Occasionally, temporary
conductivity caused by condensation is to be expected (home
and office environments fall under this category).
Pollution
degree 3
Conductive pollution occurs, or dry nonconductive pollution
occurs that becomes conductive due to condensation that is to be
expected (industrial environments and environments exposed to
outside air - but not in contact with precipitation).
Pollution
degree 4
The pollution generates persistent conductivity caused by
conductive dust or by rain or snow (exposed outdoor
environments and environments where high humidity levels or
high concentrations of fine particles occur).
Warning: This device was designed in accordance with EN 61010-1
pollution degree 2. This implies that certain restrictions in use apply that
are related to pollution which can occur within the environment of use. Refer
to the table above.
This device is only suitable for measurements in Pollution
degree class 2 environments.

AC voltage measuring range: 200.0 V, 600 V.
To measure AC or DC voltages:
1. Select the appropriate V (DC voltage) or V (AC voltage) range with
the rotary switch.
2. Connect the black test lead to the “COM” socket and the red test lead to
the “VΩmAhFE” socket.
3. Connect the test probes in parallel to the circuit under test.
The measured value appears on the display. For DC measurements: if a
negative polarity is present at the red test probe, the indicated value is
preceded by a “–” sign.
Notes:
If the measured voltage exceeds the selected range, the display
shows “1”. Select a higher range.
The displayed value may be unstable in the lower ranges, even without
input or without connecting the test probes. In this case, hold the tips
of the test probes together and make sure the meter displays zero;
then measure again.
7.5 Measuring DC Current
To avoid electrical shock and/or damage to the instrument,
disconnect the circuit power and discharge all high-voltage
capacitors before measuring current.
To avoid damage to the meter, check the meter‟s fuse before
proceeding. Use the proper terminals, function and range for your
measurement. Never place the test probes in parallel with a circuit or
component when the leads are plugged into the current terminals.
In the 10 A range, measure current for maximum 10 seconds, then
wait for 15 minutes before the next measurement.
The meter‟s ranges are: 2.000 mA, 20.00 mA, 200.0 mA, 10.00 A.
To measure current:
1. Cut off the power supply of the circuit to measure.
2. Discharge all the high-voltage capacitors.
3. Select the appropriate A (DC) range with the rotary switch.
4. Connect the black test lead to the “COM” socket and the red test lead to
the “VΩmAhFE” socket for measurements of max. 200 mA. For a
maximum of 10 A, move the red test lead to the “10A” socket. If the
