2 Applications

2.1 Intended Use / Use for Intended Purpose

The METRAFUSE FD PRO is a test instrument used for the speedy identification of which
fuse or circuit breaker is protecting a circuit.

The METRAFUSE FD PRO consists of two parts: a receiver and a transmitter. The transmit­ter is connected to the circuit under test and uses the AC circuit‘s power to generate and
inject a modified high frequency signal into the live conductor. The receiver is used to detect
the signal from the transmitter and when put in contact with the fuse or circuit breaker that is
connected to the circuit under test will indicate the presence of the transmitter signal both by
LED and beeping.

Safety of the operator, as well as that of the instrument, is only assured when it’s used for its
intended purpose.

2.2 Use for Other than Intended Purpose

Using the instrument for any purposes other than those described in these operating instruc­tions is contrary to use for intended purpose.

to failure to observe the product documentation. Furthermore, all guarantee claims are ren­dered null and void in such cases.

2.4 Opening the Instrument / Repairs

The instrument may only be opened by authorized, trained personnel in order to ensure flaw­less, safe operation and to assure that the guarantee isn’t rendered null and void. Even orig­inal replacement parts may only be installed by authorized, trained personnel.

Unauthorized modifications to the instrument are prohibited.
If it can be ascertained that the instrument has been opened by unauthorized personnel, no

guarantee claims can be honored by the manufacturer with regard to personal safety, mea­suring accuracy, compliance with applicable safety measures or any consequential dam­ages.
