All equipment subject to this directive is marked with this logo.

Disposal of used batteries

As an end user, you are legally obliged (battery law) to return all used batteries; disposal in domestic waste is prohibited!

Batteries containing contaminant material are marked with this symbol indicating that they must not be disposed of in domestic waste.

The abbreviations used for the respective heavy metals are:

Cd = cadmium, Hg = mercury, Pb = lead.

You can return your used batteries free of charge to municipal collection points or anywhere where batteries are sold!

Operation

Introduction

The Testboy® TB 4000 is a universal multimeter. This measuring instrument has been manufactured to the latest safety specifications, and guarantees safe and reliable operation. The multimeter is a valuable aid for all standard measurement tasks in trade and industry as well as for electronics hobbyists.

Safety precautions

The TB 4000 left the factory with its safety features in a perfect operating condition. The user must observe the safety information contained in these instructions in order to maintain this condition.

Caution!

Only use the safety test leads included in the scope of delivery or equivalent leads that comply with the same measurement category.

In order to avoid an electric shock, comply with the precautions when working with voltages greater than 120V (60 V) DC or 50 V (25 V) eff. AC. These values represent the limits of safe-to-touch voltages in accordance with DIN VDE. (Values given in brackets apply e.g. to the medical or agricultural sectors)
Before taking each measurement, ensure that the test leads and the test instrument are in perfect operating condition.
The test leads and probes must only be handled using the grips provided. Avoid touching the probes under any circumstances.

The test instrument may only be used for the measurement ranges specified.

Attention!

Before use, check that the instrument is functioning correctly (e.g. using a known voltage source, also see DIN VDE 0105, part 1).
