Observe prior to use!
• The instruction manual contains information and instructions which are necessary for
operating and using the instrument safely. 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.
Safety instructions
The instrument may only be used by trained personnel. 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 limits for contact
voltages in accordance with DIN VDE (values in brackets apply to restricted areas, for
example agricultural sectors).
• The measuring instrument is only to be used in electrical circuits with up to 600 V nominal
voltage.
• Measurements may only be taken near electrical installations under the direction of an
authorised qualified electrician - never alone.
• The instrument may only be touched at the designated grip areas, the display elements
must not be covered. If the instrument is not held by the designated grip areas, or outside
the limits of the grips, the operator will be at risk of electric shock.
• If operator safety can no longer be guaranteed, the instrument is to be taken out of service
and prevented from being inadvertently used. This is the case if the instrument:
- Is obviously damaged. e.g.
- Housing breakages
- Defective measurement cables
- Leaking batteries
- Does not carry out the required measurements
- Has been stored too long in unfavourable conditions
- Has been exposed to mechanical stresses during transit.
• Protect from direct solar radiation to prevent the instrument from heating up. This is the
only way to guarantee the instrument will function perfectly and have a long service life.
• If the instrument needs to be opened, this may only be carried out by a qualified specialist.
Prior to opening, the instrument is to be switched off and disconnected 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 cannot be guaranteed.
• Modifications to the instrument will completely void any right to claims under the manufac-
turer's guarantee and warranty.
• The clamp meter adapter must not be used when the battery compartment is open.
• Check and replace batteries, if necessary, before use.
• Always store in a dry place.
• The instrument must not be used in explosive environments.

Certified safety (verified by TÜV
Rheinland)
The instrument complies with
the WEEE Directive (2012/16/
EU)
Application around and removal
from HAZARDOUS LIVE con-
ductors is permitted.
• Always check the instrument is in perfect working order prior to and after use. Test the
instrument on a known current source.
• If there is any battery leakage, the instrument must not 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.
Intended use
The instrument may only be used under the conditions and for the purpose for which it was
designed:
• The instrument complies with the CAT IV measurement category and rated voltage of 600 V
to earth.
The CAT IV measurement category is used at the source of low voltage installations, e.g. build-
ing connection, main fuse, and meter.
The instrument may only be used in the fields of application defined in the instruction manual.
Any application deviating from this is considered to be improper and unchecked use and may
result in accidents or instrument damage. Any improper use will completely void any right to
claims under Testo's guarantee and warranty.
The manufacturer is not responsible for damage to property or personal injury caused by the
following:
• Failure to comply with the instruction manual
• Modifications to the instrument not approved by the manufacturer
• The use of spare parts not approved by the manufacturer
• Use when under the influence of alcohol, drugs, or medication
The instrument must not be used for the following purposes:
• In potentially explosive atmospheres: the instrument is not explosion-proof!
• When it rains: risk of electric shock!

Carrying out a test
The contents of the testo 760 documentation must have first been read and understood.
Measuring direct currents (DC)
1. Connect the testo 760 and clamp meter adapter to the measurement cables: black cable to
the COM jack; red cable to jack V//diode/capacity.
2. Switch on the testo 760.
3. Activate DC mV measuring mode for current measurement: press key V 4 x.
4. Switch on the clamp meter adapter.
- A green or red LED indicates readiness for operation.
5. Close the clamp jaws of the clamp meter adapter. Make sure that no conductor is enclosed.
> Compensate the direct current offset: press ZERO < 1 second.
6. Place the cables being measured centrally within the clamp.
- The measured value is shown on the LC display.
Measuring alternating currents (AC)
1. Connect the testo 760 and clamp meter adapter to the measurement cables: black cable to
the COM jack; red cable to jack V//diode/capacity.
2. Switch on the testo 760.
3. Activate AC mV measuring mode for current measurement: Press button V 3 x.
4. Switch on the clamp meter adapter.
- A green or red LED indicates readiness for operation.
5. Place the cables being measured centrally within the clamp.
