Before using the instrument, read the instruction manual carefully and comply with all aspects of it. Keep this document to hand so that you can refer to it when necessary. Forward this documentation to any subsequent users of the instrument. • If the manual is not followed, or if you fail to observe the warnings and instructions, there is a risk of fatal injury to the user and damage to the instrument.

During all operations, please observe the Employers' Liability Insurance Association provisions for health and safety at work. • In order to prevent electric shock, take safety precautions when working with voltages greater than 120 V (60 V) DC or 50 V (25 V) rms. AC. These values are the limit for contact voltages in accordance with DIN VDE (values in brackets apply to restricted areas, for example agricultural sectors). • The measuring instrument may only be used with a maximum voltage of 600 V. • Measurements that are dangerously close to electrical installations must only be carried out under the direction of a qualified electrician, not by oneself. • The instrument may only be touched at the designated grip areas, the display elements must not be covered. • If the safety of the operator can no longer be guaranteed, you must decommission the instrument and ensure that it cannot be used inadvertently. This applies if the instrument: • has obvious indications of damage - cracks on the housing - defective test leads - leaking batteries • will no longer carry out the required measurements • was stored for too long in unfavourable conditions • was exposed to mechanical stresses during transport. • Prevent the instrument from being heated due to exposure to direct sunlight. This is the only way to ensure that the instrument functions perfectly and has a long service life. • If the instrument needs to be opened, this should only be carried out by an expert. Before being opened, the instrument must be switched off and isolated from all electrical circuits. • Maintenance work that is not described in this documentation must only be carried out by trained service technicians. • If the instrument is modified in any way, operational safety can no longer be guaranteed. • Modifications or alterations to the instrument will result in the complete invalidation of any warranty or guarantee claims against the manufacturer. • It is not permitted to use the instrument in an explosive environment. • Before and after use, always check that the instrument is in peak working order. To do this, test the instrument at a known current source.
4 Intended use 5 • High-frequency electromagnetic fields (HF) can influence the measurement result and result in the wrong information being displayed. This influence is temporary and will not damage the measuring instrument in any way. As soon as the measuring instrument is removed from the influencing HF field, its original accuracy will be re-established. Known sources of these high-frequency electromagnetic fields are radio or mobile telephony equipment, for example. If this type of equipment should influence the measuring instrument, switch it off or increase the distance between the equipment and the measuring instrument. • The instrument must not be used while its battery compartment is open. • Batteries must be checked before use and changed if necessary. • Storage areas must be dry. • If there is any battery leakage, the instrument must no longer be used until it has been checked by our Customer Service. • The battery acid (electrolyte) is highly alkaline and electrically conductive. Risk of acid burn! If the battery acid comes into contact with your skin or clothing, thoroughly rinse the areas affected immediately with plenty of water. If battery acid gets into your eyes, rinse them immediately with plenty of water and seek medical advice. Pos: 7 /TD/Überschr iften/Elektr. Messgr ößen/4.

Measurement category CAT IV is for use at the source of voltage installations, e.g. building connection, main fuse, meter. The instrument may only be used in the fields of application described in the instruction manual. Any other application is considered improper and untested usage, and can result in accidents or damage to the instrument. Any misuse will result in the complete invalidation of any warranty or guarantee claims against Testo. The manufacturer is not responsible for any damage to property or personal injury resulting from the following: • Failure to observe the instruction manual • Instrument modifications not approved by the manufacturer • The use of spare parts not approved by the manufacturer • Use under the influence of alcohol, drugs or medication The instrument must not be used for the following circumstances: • In potentially explosive atmospheres: the instrument is not explosion-proof! • When there is rain or other precipitation: risk of electric shock!

11 Authorizations (testo 770-3 only) 25 interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. Caution Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Shielded interface cable must be used in order to comply with the emission limits. Warning This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
