Frequently Asked Questions - DCM100 VELLEMAN

How to measure AC voltage with the DCM100?

To measure AC voltage, set the function switch to V~. Press SELECT to choose AC. Connect the black lead to the COM terminal and the red lead to the VΩ terminal. Place the test probes on the circuit to be measured. Read the value on the LCD display.

What is the accuracy of voltage measurement?

Accuracy varies by range. For example, on the 200 mV DC range, the error is ±(0.8% + 3). Refer to the specifications table in the manual for each range.

How to measure current with the clamp?

Set the selector to 20A or 200/500A. Press the trigger to open the jaws and insert a single conductor. Close the jaws and read the value. Ensure the circuit voltage does not exceed 600 V.

How to replace the multimeter batteries?

Turn off the device and disconnect the leads. Remove the screw of the battery compartment on the back. Replace the 3 AAA/LR03 batteries observing polarity. Close and screw back.

What does the display 'OL' mean?

OL means Over Limit (range exceeded). It indicates that the measured value exceeds the selected range. Switch to a higher range.

How to use the continuity function?

Set the selector to Ω→•••. Press SELECT until the continuity symbol (•••) appears. Connect the leads to the circuit points. The beeper activates if the resistance is less than about 70 Ω ± 30 Ω.

What is the overvoltage category of this device?

The DCM100 is rated CAT III 600 V. This means it is suitable for measuring on fixed installation circuits (distribution boards, lighting) up to 600 V.

How to test a diode?

Set the selector to Ω→••• and press SELECT to choose the diode symbol (▶). Connect the red lead to the anode and the black to the cathode. The threshold voltage is displayed (about 0.6 V for silicon).

What to do if the device does not turn on?

First check the batteries. If the low battery symbol (+ -) appears, replace the 3 AAA batteries. Also ensure the internal fuse is not blown.

How to use the Data Hold function?

During a measurement, press the D-hold button to freeze the displayed value. Press again to release. This allows you to comfortably read the measurement after removing the probes.

Risk of electric shock during operation. Be very careful when measuring live circuits.

• Never exceed the limit value for protection. This limit value is listed separately in the specifications for each range of measurement.
• Do not touch unused terminals when the meter is linked to a circuit, which is being tested.
• Never use the meter with CAT III installations when measuring voltages that might exceed the safety margin of 600 V above earth ground.
• Set the range selector at its highest position if the intensity of the charge to be measured is unknown beforehand.

DCM100

• Disconnect the test leads from the tested circuit before rotating the range selector in order to change functions.
• When carrying out measurements on a TV set or switching power circuits, always remember that the meter may be damaged by any high amplitude voltage pulses at test points.
• Always be careful when working with voltages above 60 VDC or 30 VAC rms. Keep your fingers behind the probe barriers at all times during measurement.
• Never perform resistance, diode or continuity measurements on live circuits. Make sure all capacitors in the circuit are depleted.
• Always hold the device behind the finger guard (see General Description, nr. 12).
• Comply with the local and national safety regulations. Use personal protective equipment, such as approved rubber gloves, face protection and flame-resistant clothing, to prevent shock and arc blast injury where hazardous live conductors are exposed.
• Do not use this device to measure a current with a frequency above 1 kHz.

7. 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.

DCM100

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 10 m apart from a CAT III- or 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 10 m apart from of 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.

Warning:

This device was designed in accordance with EN 61010-1 installation category CAT III 600 V. This implies that certain restrictions in use apply that are related to voltages and voltage peaks which can occur within the environment of use. Refer to the table above.

This device is only suitable for measurements up to 600 V in CAT III

8. 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 DVM 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)
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)

DCM100

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.
