The following symbols appear on the products:
Attention! Refer to Manual
Double/Reinforced Insulation
Do not apply around or remove from HAZARDOUS LIVE
conductors without additional protective means.
“Additional protective means” can be:
- de-energizing the circuit
- wearing protective clothing suitable for high voltage work.
Do not dispose of this product as unsorted municipal
waste. Contact a qualified recycler for disposal.

The flexible current transformer is manufactured and tested in accordance with
safety regulations IEC/EN 61010-1 / -031 /-2-032. If used for its intended
purpose, safety is assured for the user, the device and the DUT.
Read the operating instructions carefully and thoroughly before placing
the device into operation. Observe and follow all points included therein.
Make the operating instructions accessible to all users.
In particular, observe the following safety instructions.
• Always inspect the electronics unit, connecting cable, and flexible
probe for damage before using this product. Do not use product if
damaged.
• This product must be used only by qualified personnel practising
applicable safety precautions.
• Never apply the probe around bare conductors with hazardous
voltages without having the appropriate permission to perform
such work and without wearing protective clothing and gloves as
required.
• Never apply the probe around bare conductors with voltage levels
over 1000V to ground.
• Always connect electronics unit to measuring device before
installing the flexible measuring head.
• Never change batteries while measurement head is installed on
conductor.
• Never connect or disconnect the external power supply while the
measurement head is installed on a conductor.
• Never connect the output to any equipment with a common mode
voltage to earth greater than 30 Volts.
• If the probe is used in a manner not specified by the
manufacturer the protection provided by the equipment may be
impaired.

2. INTRODUCTION
The METRAFLEX are AC current probes utilising Rogowski
principle. They can be used to measure AC current up to 3000A
by being connected to an appropriate measuring device
(multimeter, data logger, power analyser etc.). The flexible probe
allows current measurements on conductors that are hard to
reach.
The probes provide an AC output voltage of 0…3V (METRAFLEX
3000/3001/3003) or 0…1.5V (METRAFLEX 3001XL/3003XL),
proportional to the current being measured with three selectable
ranges.
