Frequently Asked Questions - DVM900 VELLEMAN

How to measure DC voltage with the DVM900?

Set the rotary selector to the V (DC) range. Connect the red lead to the VΩHz terminal and the black to COM. Press SELECT to choose DC. Place the probes in parallel with the circuit. Read the value and polarity on the display.

What is the maximum measurable DC voltage?

The maximum measurable DC voltage is 700 V. Never exceed this limit to avoid damaging the device and risking electric shock.

How to test a diode with this multimeter?

Set the selector to the Ω→+••• range. Press SELECT to choose diode mode. Connect the red probe to the anode and the black to the cathode. The display shows the approximate forward voltage.

What does the display 'OL' mean?

The display OL (Over Limit) indicates that the measurement exceeds the selected range. Select a higher range or check that the circuit is not out of limits.

How to replace the battery of the DVM900?

Turn off the device and disconnect the leads. Unscrew the battery compartment screw on the back. Replace the used battery with a new 3.7 V one, observing polarity. Close the case.

The multimeter does not turn on, what to do?

First check the battery. If the display remains off, the battery may be discharged. Replace it. If the problem persists, the internal fuse may be faulty. Refer to the manual for fuse replacement.

Can I use the DVM900 on industrial circuits?

No, the DVM900 is designed for domestic and office use (pollution degree 2). It is not suitable for industrial use (pollution degree 3 or 4) unless otherwise indicated.

How does the non-contact voltage detection (NCV) work?

Set the selector to NCV. Bring the sensor (top part of the multimeter) close to a conductor. The beeper activates if AC voltage ≥ 90 V is detected. Note that detection may be affected by insulation or interference.

What are the replacement fuses?

The DVM900 uses two fuses: F0.8 A/1000 V (6.75 x 33 mm) for current ranges up to 600 mA, and F15 A/1000 V (6.75 x 33 mm) for the 15 A range. Use only fuses with the specified ratings.

How to measure temperature with the DVM900?

Connect the thermocouple (NiCr-NiSi probe) to the VΩHz (red) and COM (black) terminals. Set the selector to °C/°F. Press SELECT to choose the unit. Place the probe on the object to measure and read the temperature.

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.

DVM900

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 II 700 V and CAT IV 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 700 V in CAT II and up to 600 V in CAT IV

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)

DVM900

DVM900

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.

To replace the battery:

• Switch off the meter.
• Remove the screw at the back of the case and gently open the housing.
• Remove the old battery and insert a new one.
• Close the housing and fasten the screw.

Battery: 1 x 3.7 V, make sure to respect the polarity

12. Troubleshooting

If the device acts abnormal while measuring, this means that the internal fuse is defective.

Keep in mind that a low battery level could lead to incorrect measurements. Replace the battery on a regular basis.

(Tip: the reduced luminosity of the backlight/LCD display indicates a low battery level.)
