Frequently Asked Questions - DVM860BL VELLEMAN

How to measure AC voltage with the DVM860BL?

Turn the selector to the V~ position. Connect the test leads (red to V/Ω, black to COM). Place the probes on the circuit terminals. Read the value on the display.

How to replace the multimeter battery?

Turn off the device. Remove the back cover by unscrewing the screw. Replace the used 9V battery with a new one (type 6F22). Close the compartment and screw the cover back on.

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

These indications mean range overload. The measurement is higher than the selected range. Select a higher range or check your connections.

How to perform a continuity test?

Set the selector to the diode or sound wave symbol (continuity test). Connect the leads. If the circuit is closed (low resistance), a beep sounds.

What safety precautions should be observed?

Never measure a voltage higher than 1000 V DC or 750 V AC. Use leads in good condition. Observe the safety categories CAT II. Do not touch the metal tips during measurements.

Is the DVM860BL auto-ranging?

No, this model is manual ranging. You must select the appropriate range with the rotary switch for each type of measurement.

How to measure DC current?

Turn the selector to a A-- position (DC current). Connect the red lead to the 10A jack (for high current) or mA (for low current). Place the multimeter in series in the circuit.

How to use the hold function (HOLD)?

Press the HOLD button to freeze the displayed value. Press again to release. Useful for reading a measurement in a hard-to-reach place.

How to clean the device?

Use a soft, dry cloth to wipe the case. Never use solvents, alcohol or abrasive cleaners. Avoid moisture.

Where can I find the replacement fuse?

The replacement fuse is generally available from electronics retailers. Refer to the manual for the exact type. Use a fuse of identical rating to avoid damage.

6.1. Data-Hold Button

Press the DATA-H button if you want the device to hold the measured value. Press this button again to disengage the data hold button.

6.2. Maximum Value Hold Button

Press the MAX.H button during your measurements to display the highest value measured so far. Press the button again to remove the value from the display.

6.3. Func. Button

Press this button during current and voltage measurements to alternate between DC and AC.

Press the button during temperature measurements to alternate between ^ C and ^ F.

Press the button while testing diodes or continuity to alternate between these two.

6.4. Range Selection

The auto range setting is used when measuring current, voltage and resistance. Press the RANGE button to select the manual range setting. The next level up is selected each time you press the button. Press the button when the highest range is selected in order to select the lowest range.

Hold the button for more than 2 seconds to return to the auto range setting.

The symbol is displayed when the battery voltage is less than 4V. Note, however, that this symbol may be displayed because you are using the backlight (which uses a lot of power), even though the actual battery charge >4V. In other words, you should only replace the batteries if the symbol is displayed when the backlight is not being used.

6.6. Auto Power Off

The device will deactivate automatically if no button is pressed for 15 minutes. The auto power off function is announced by five short beeps and one long one. Touch an arbitrary button or the selector to restore the device to normal working condition. Press the DATA HOLD button while the device is powering on if you want to disable the auto power off function.

6.7. Preparation for Measurement
