1. Introduction

To all residents of the European Union

Important environmental information about this product

This symbol on the device or the package indicates that disposal of the device after its lifecycle could harm

the environment.

Do not dispose of the unit (or batteries) as unsorted municipal waste; it should be taken to a specialized

company for recycling.

This device should be returned to your distributor or to a local recycling service.

Respect the local environmental rules.

If in doubt, contact your local waste disposal authorities.

Thank you for choosing Velleman! Please read the manual thoroughly before bringing this device into service. If the

device was damaged in transit, don't install or use it and contact your dealer.

2. Safety Instructions

 Measurement category III is for measurements performed in the building installation.

 Measurement category II is for measurements performed on circuits directly connected to the low-voltage

installation.

 Measurement category I is for measurements performed on circuits not directly connected to the mains.

 When using this multimeter, the user must observe all normal safety rules concerning:

o protection against the dangers of electric current.

o protection of the multimeter against misuse.

 For your own safety, only use the test probes supplied with the instrument. Before use, check that they are in

good condition.

 If the meter is used near noise-generating equipment, be aware that the display may become unstable or may

indicate large errors.

 Do not use the meter or test leads if they look damaged.

 Use the meter only as specified in this manual; otherwise, the protection provided by the meter may be impaired.

 Use extreme caution when working around bare conductors or bus bars.

 Do not operate the meter around explosive gas, vapour or dust.

 Verify the meter's operation by measuring a known voltage. Do not use the meter if it operates abnormally.

Protection may be impaired. When in doubt, have the meter serviced.

 Use the proper terminals, function and range for your measurements.

 When the range of the value to be measured is unknown, check that the range initially set on the multimeter is the

highest possible or, wherever possible, choose the auto-ranging mode.

 To avoid damages to the instrument, do not exceed the maximum limits of the input values shown in the technical

specification tables.

 When the multimeter is linked to measurement circuits, do not touch unused terminals.

 Caution when working with voltages above 60VDC or 30VAC rms. Such voltages pose a shock hazard.

 When using the probes, keep your fingers behind the finger guards.

 When making connections, connect the common test lead before connecting the live test lead; when

disconnecting, disconnect the live test lead before disconnecting the common test lead.

 Before changing functions, disconnect the test leads from the circuit under test.

 For all DC functions, including manual or auto-ranging, to avoid the risk of shock due to possible improper

reading, verify the presence of any AC voltages by first using the AC function. Then select a DC voltage range

equal to or greater than the AC range.

 Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes or

capacitance.

 Never perform resistance or continuity measurements on live circuits.
