WARNING Sources of danger include, for example, mechanical parts that can cause serious injuries. Objects are also at risk (e.g. damage to the instrument).

WARNING An electric shock can result in death or serious injuries and endanger the function of objects (e.g. damage to the instrument).

WARNING Never point the laser beam at eyes, either directly or indirectly via a reflective surface. Laser radiation can cause irreparable damage to eyes. The laser beam must be deactivated when conducting measurements close to people.

General safety information

WARNING Unauthorised modification and/or changes to the instrument are not permitted for reasons of safety and approval (CE). In order to ensure safe and reliable operation of the instrument, you must always observe the safety information, warnings and the section "Intended use".

WARNING Observe the following information before using the instrument: | Avoid operating the instrument near to electric welding equipment, induction heaters or other electromagnetic fields. | After abrupt temperature fluctuations, the instrument must be allowed to adjust to the new ambient temperature for approx. 30 minutes before use, in order to stabilise the IR sensor. | Do not expose the instrument to high temperatures for a long period of time. | Avoid dusty and humid environments. | Measuring instruments and their accessories are not toys, and must be kept out of the reach of children! | When working in industrial facilities, observe the accident prevention regulations for electrical systems and equipment as established by the employers' liability insurance association.

Please observe the five safety rules:

1 Disconnect
2 Secure against reactivation
3 Ensure isolation from the power supply (check that there is no voltage on both poles)
4 Earth and short-circuit
5 Cover adjacent live parts

Disposal

Dear Testboy customer, Purchasing our product gives you the option of returning the instrument at the end of its lifespan to suitable collection points for waste electrical equipment.

The WEEE directive regulates the return and recycling of old electrical appliances. Manufacturers of electrical appliances are obliged to take back and recycle all electrical appliances free of charge. Electrical appliances may then no longer be disposed of through "conventional" waste disposal channels. Electrical appliances must be recycled and disposed of separately. 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 318 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 engineers. With its CAT IV 1000V classification, the TB 318 multimeter is ideal for use outdoors too. With a measurement range of up to 1500 V DC, this multimeter can also be used in the area of photovoltaics.

Safety precautions

The TB 317 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).

True RMS

When using the True RMS function to measure non-sinus wave forms, small measurement errors can occur compared with conventional measurement procedures. Sinus-form and non-sinus form signals can be accurately measured using the True RMS function.

Maintenance

The instrument does not require special maintenance when used as specified in these operating instructions.

Cleaning

Use a damp cloth and mild household detergent to clean the instrument should it become soiled through daily use. Never use harsh cleaning agents or solvents to clean the instrument.

Battery replacement

Replace the batteries when the battery symbol appears on the display. Remove the test leads from the instrument before changing the batteries! Remove the screws at the back, open the battery compartment and remove the discharged battery. Insert new batteries (1 x 9 V block). Refit the battery compartment lid and secure with screws.

Only use the batteries specified! Batteries must not be disposed of in domestic waste! Observe the statutory regulations pertaining to disposal!

Changing the fuse

Remove the screws at the back, open the battery compartment, remove the holster, and remove the housing screws and fuse. Insert a new fuse (F 2A). Reassemble in the reverse order and secure with screws.

Only use the fuses specified!
