Frequently Asked Questions - DCM270 VELLEMAN

How to replace the battery of the DCM270?

Open the compartment at the back of the device, remove the old battery and insert a new 9V battery (type 6F22) observing the polarity.

What to do if the screen shows nothing?

Check that the battery is in good condition and properly installed. If the problem persists, replace the battery.

How to use the continuity test?

Turn the selector to the 'diode/continuity' position (sound symbol). Connect the leads, touch the probes to two points of the circuit. If the resistance is below 50 Ω, a beep sounds.

What is the maximum measurable voltage in DC current?

The maximum DC voltage is 600 V. Never exceed this limit to avoid damaging the device.

Can the DCM270 measure AC currents?

Yes, it measures AC currents up to 10 A. Use the '10A' terminal for measurements above 200 mA.

How to clean the multimeter?

Use a soft dry cloth. Never use solvents or abrasive products. Avoid moisture.

What does the display '1' or 'OL' mean?

This indicates an overload of the measurement range or an open circuit. Select a higher range or check your connections.

What are the protection fuses?

The multimeter is protected by a fuse for the current range. In case of overload, replace it with an identical fuse (Velleman reference).

How to measure resistance?

Set the selector to the resistance range (Ω). Connect the leads, touch the probes to the terminals of the resistor. Read the value on the display.

5. Safety

Important information with reference to safety, consult the manual

Double insulation

This meter has been designed with attention to safety, but the user must also take care to respect the safety prescriptions described below.

1. Do not exceed the maximum values for current or voltage measurements.
2. Use extreme caution when working with voltages in excess of 25V AC rms. These voltages are considered a shock hazard.
3. Never operate the device if the back panel or the cover of the battery or fuse compartment is not securely in place.
4. Input limits: 200A (AC current), ±200A (DC current)

6. Operation

a) AC Current Measurements

1) Set the function switch to the ACA range.
2) Press the trigger and enclose a single conductor with the jaws, which must be fully closed (see figure).
3) Read the ACA value on the LCD.

b) DC Current Measurements

1) Set the function switch to the DCA range.
2) Press the ZERO key to reset the display.
3) Press the trigger to open the jaws.
4) Enclose the conductor to be measured. Remember: the jaws must be fully closed.
5) Read the DCA value on the LCD.

c) Non-contact Voltage Measurements

WARNING

Risk of electrocution. Before use you should always test the voltage detector on a known live circuit to verify proper operation of the meter

1) Hold the probe against the hot conductor or against the hot side of the electrical outlet..
2) The two detector LEDs light up red if an AC voltage is detected.

NOTE: The conductors in an electrical cord are often twisted. Rub the probe tip along a length of cord to be sure the tip passes in close proximity to the live conductor.

NOTE: The detector is a sensitive device. Static electricity or a different energy source may randomly trigger the sensor at random. This is simply part of the normal operation of this device, it is not a malfunction.

d) Frequency Measurements (DCM269 only)

1) Put the function switch in the Hz-position.
2) Close the jaws completely around the conductor to be measured.
3) Read the frequency value on the LCD.

e) Flashlight

Hold the top button to turn on the flashlight.

f) Data-Hold

Press the "Hold backlight" button to freeze the current reading on the LCD. The word "HOLD" will appear on the LCD when the data-hold mode is activated. Simply press the "Hold backlight" button again to return to the normal display mode. The word "HOLD" is erased from the display.

g) Backlight

Hold the "Hold backlight" button for more than 2 seconds to turn on the backlight. This will also activate the data-hold function. Press the button momentarily to deactivate the data-hold function. Hold the "Hold Backlight" button for more than 2 seconds to deactivate the backlight.

h) Auto Power OFF

The device is turned off automatically after 7 minutes if no button is pressed.

i) Battery Replacement

1) Replace the batteries when the low-battery symbol is displayed.
2) Turn off the device and loosen the screw of the battery compartment.
3) Remove the compartment cover and replace the two 1.5V AAA batteries.
4) Replace the cover and fasten the screw.
