1. General Instructions

This instrument has been designed in accordance with IEC61010 Standard that
regulates requirements for the electronic measuring equipment and current measuring
clamps. In order to get the best out of this equipment, please read the present user
manual carefully and always comply with the safety instructions.
Safety measures
Preliminary
• This equipment can be used to carry out measurements in the CAT.III 600V
environment.
• When using this clamp, the user should comply with all the safety measures
regarding:
- Protection against the electric current hazards.
- Protection of the ammeter clamp against incorrect use.
• For your own security, only use the test probes supplied with the instrument.
Before using them, check that these are in good condition.
During use
• Before carrying out any measurements, let the instrument warm up for at least 30
seconds.
• If you use the clamp near any noise generating equipment, bear in mind that the
screen may become unstable or show errors of importance.
• Do not use the clamp or the test probes if they appear to be damaged.
• Only use the clamp as specified in this manual, as any use may damage its
protection.
• To avoid damage to the equipment, do not exceed the maximum limits of the
input values shown on the technical specifications tables.
• Check the rotary switch and make sure it is in the correct position before starting
a new measurement.
• Be extremely careful when working near bare conductors or busbars.
• Any accidental contact with the conductor may cause an electric shock.
• Be careful when working with voltages higher than 60V DC or 30V AC rms. This
type of voltage has a risk of electric shock.
• Before changing the function, disconnect the test probe from the circuit that is
being tested.
• Keep your fingers behind the protection ring when measuring.
• Change the battery when the
