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 transmit-

ter 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 instruc-

tions is contrary to use for intended purpose.

2.3 Liability and Guarantee

Gossen Metrawatt GmbH assumes no liability for property damage, personal injury or con-

sequential damage resulting from improper or incorrect use of the product, in particular due

to failure to observe the product documentation. Furthermore, all guarantee claims are ren-

dered null and void in such cases.

Nor does Gossen Metrawatt GmbH assume any liability for data loss.

2.4 Opening the Instrument / Repairs

The instrument may only be opened by authorized, trained personnel in order to ensure flaw-

less, safe operation and to assure that the guarantee isn’t rendered null and void. Even orig-

inal 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, mea-

suring accuracy, compliance with applicable safety measures or any consequential dam-

ages.

4 Preparation

Before using the METRAFUSE FD PRO, prepare as follows:

1. Establish the power supply 7.

2. Turn the device on 8.

3. Conduct a pre-use-check 8.

After you have performed these steps, you can find fuses and circuit breakers 9.

4.1 Electrical Power Supply

The receiver and transmitter are powered differently.

Receiver (M660B)

The METRAFUSE FD PRO receiver is powered by a 9 V Alkaline battery type PP3/MN 1604/

6F22 or equivalent. One battery is included in delivery; replacements must be provided.

You have to install the battery before first use and replace it later if depleted. Required tools:

Philips screwdriver.

The receiver is switched off.

1. Place the receiver face down on a stable surface.

2. Loosen and remove the screw from the battery compartment cover.

3. Unlock and remove the battery compartment cover.

4. Connect the 9 V battery to the battery snap.

5. Only the battery specified in the technical data (6) may be connected and used.

6. Insert the 9 V battery into the battery compartment, making sure that the wires are not

damaged (e.g. squished).

7. Place the battery compartment cover onto the battery compartment and press it until it

audibly clicks into place.

8. Secure the battery compartment cover with the screw.

The receiver is provided with power.

The receiver LEDs provide status information on the battery power:

To maximize battery life, the receiver will automatically switch off after six minutes of inactiv-

ity. To resume testing after this period, it can be turned on again 8.

Transmitter (M660A)

The transmitter is powered by the circuit under test (100 V …250 V AC; 50 Hz … 60 Hz) it is

connected to. The transmitter is connected to it either by the mains cable or the fused test

probe set. Both are described in chapter Operation 9.

The transmitter current is < 20 mA.

Receiver on LEDs are solid green: battery full

Receiver on LEDs are flashing: battery power low (approx. 20 %);

replacing required soon

Receiver on LEDs and signal strength LEDs flashing: battery almost discharged;

replacing required
