Frequently Asked Questions - DVM8030 VELLEMAN

How to install the DVM8030 odometer ?

Attach the sensor to the front fork and the magnet to a spoke of the wheel. Mount the meter bracket on the handlebar and insert the meter. Follow the manual diagram for alignment.

Which battery to use ?

Use a CR2032 button cell battery. Remove the back cover of the meter to replace the battery.

How to set the wheel circumference ?

Measure the wheel diameter in mm, multiply by π (3.1416) and enter this value in the odometer settings. Refer to the manual's table for standard values.

Why is the display flashing ?

This generally indicates a low battery. Replace the battery with a new one. If the problem persists, check the battery contact.

How to reset the partial distance to zero ?

Press and hold the MODE button for 3 seconds on the partial distance screen. The display will reset to zero.

Is the odometer waterproof ?

It is splash-resistant but should not be immersed. Protect it from heavy rain and high-pressure washing.

How to change the unit from km to miles ?

In the settings menu, select the unit option (KM or MI) using the SET button. Confirm with MODE.

The displayed speed seems inaccurate, what to do ?

Check the set wheel circumference and the alignment of the sensor and magnet. A deviation of 1 mm can cause errors.

Can I use the odometer on multiple bikes ?

Yes, by purchasing an additional mounting kit. You will need to reconfigure the wheel circumference for each bike.

Where to find spare parts ?

Spare parts (brackets, magnets, batteries) are available from Velleman or authorized dealers. Contact customer service to order.

2. Safety Instructions

Keep this device away from children and unauthorized users.

NEVER TOUCH ROTATING PARTS as they may cause serious or even fatal injury.

CAUTION: due to the persistence of vision, rotating objects might appear stationary or even move in the opposite direction. This effect is strengthened under fluorescent or stroboscopic lamps. Always make sure rotating parts have come to a full stop before touching them.

Use extreme caution when the laser beam is turned on.

When device is in use, do NOT look directly or indirectly (reflectance) into the laser beam. NEVER point the laser beam directly or via a reflecting surface towards other people's or animals' eyes. Permanent eye damage will result. Do not point the laser beam towards highly explosive gasses.

Visible laser radiation. Do not stare into the beam as eye damage may occur. This device contains a class 2 laser.

Output power does not exceed 1 mW, wavelength 635\~660nm.

4. Fe atures

• 6 digit s LCD
• auto power-off
• comes with: storage box, wristlet, batteries, reflective marker, user manual
• option al telescopic tripod (not incl.): CAMB17

5. Preparation

• Prior to using the tachometer, a piece of reflecting marker (incl.) must be attached to the rotating device. Make sure the rotating device has come to a full stop before touching it.
• Make sure the measuring area is clean, free of oil and dust.
• Cut one piece of the reflective marker and attach it to the rotating device. Measurement can be done on the side or at the top of a rotating shaft. When measuring at the top, do not attach the marker to close to the centre. The size of the marker depends largely on the size of the rotating device, but it should never cover more than half of the circumference.

Notes:

- in case no reflective marker can be attached, check whether a measurement can be performed without. If the rotating device consists of multiple reflective surfaces (e.g. fan blades), enter the number (see §6: Use).

- Do not attach more than one marker to the same surface.

6. Use

Refer to the illustrations on pages 2 and 3 of this manual.

• Remo ve the sensor cover [1] by releasing the screw at the back of the device and sliding the cover upwards.
• Press the button to switch the device on. The device will switch off automatically after ±2 minutes of inactivity.
• Press the Unit button to switch from rpm (rotations per minute) to rps (rotations per second) and back.
• Press and hold the Uni: button for ±2s to switch on the backlight. Press and hold again for ±2s to switch it off.
• Press and hold the ▲ button. The sensor [2] produces a red laser-beam. Switch on the rotating device and aim the beam at the reflective marker. To avoid multiple reflections, do not aim the beam perpendicular to the marker but under an angle of ±30°. Best measuring distance is between 10 and 40cm (4" \~ 15").

Note: when the display shows OL, the measured value is outside of the measuring range (see §10: technical specifications)

• Release the button : o end the measuring session.
• When the ▲button is not pressed the device is in hold-mode [A].

- Press the Func. button to show the maximum measured value of the previous session [B].

- Press the Func. button again to show the minimum measured value of the previous session [C].

- Press the Func. button again to set the number of reflecting surfaces that rotating device contains (e.g. when measuring the speed of a fan with 5 reflective blades, set to 5). Use the ▲ button to increase the value. Range from 1 \~ 9. After 9, value returns to 1. Press the Func. button to exit.

Note: for a normal measurement with 1 reflective marker, the number must be set to 1.

- When the battery indicator [F] is shown, replace the batteries (see §9).

- Alwa ys place the sens) r cover [1] back when the device is not in use.
