Description

The arrow located on the closing unit indicates the current flow direction. It is assumed that the current is flowing in the positive direction if it is flowing from the source to the receiver. Such probe orientation is required for a correct power measurement.
The output signal is supplied by a 2.5-meter lead with a pin adapted for the socket in the meter.

F-xA coil

F-1A, F-2A and F-3 flexible coils (Rogowski coil) are used to measure the alternating current in the range from 40 Hz up to 20 kHz and current up to 3000 A (10 kA peak at 50 Hz)
The only difference between the F-1A, F-2A and F-3A flexible coils is the coil size. The electrical parameters are identical.
The output signal if voltage proportional to the derivative of the measured current, with the sensitivity equal to 38.83 mV/1000 A for 50 Hz and 46.6 mV/1000 A for 60 Hz.

F-xA1 coil

Flexible clamps (Rogowski coil) F-1A1, F-2A1 and F-3A1 are probes of a double- increased sensitivity comparing to F-1A/F-2A/F-3A, which translates into halved measuring range for current up to 1500 A
The output signal is voltage proportional to the measured current derivative at the sensitivity of 77.66 mV/1000 A for 50 Hz and 93.19 mV/1000 A for 60 Hz

F-xA6 coil

Flexible probes (Rogowski coil) F-1A6, F-2A6 and F-3A6 are clamps of a double- reduced sensitivity comparing to F-1A/F-2A/F-3A, which translates into doubled measuring range for current up to 6000 A.
The output signal is voltage proportional to the measured current derivative at the sensitivity of 19.415 mV/1000 A for 50 Hz and 23.3 mV/1000 A for 60 Hz

Safety

NOTE!
Do not use non-insulated coils for conductors with a potential exceeding 1000 V with respect to the ground, in systems with the measurement category higher than III and systems of measurement category IV with potential exceeding 600 V.

Operation

To measure the current, open the coil slightly by turning the clasp, clamp them on the conductor with flowing current and roughly center the conductor relative to the coil loop. Pay attention to the direction of the arrow, to avoid the power measurement error.

NOTE!
Follow the instructions for mechanical limitations of the coils. Mechanical damage to the coil is not covered by the warranty.

**** Do not pull by force

Operation

Do not bend forcibly

Operation

Do not pack in a bent state

Operation

Cleaning and maintenance

**NOTE!**
Apply only maintenance methods specified by the manufacturer in this manual.

Before cleaning, disconnect the coil from the tested circuit and the meter.
The coil may be cleaned with a soft, damp cloth using all-purpose detergents. Do not use any solvents.

Dismantling and utilization

Worn-out electric and electronic equipment should be gathered selectively, i.e. it must not be placed with waste of another kind.
Worn-out electric equipment should be sent to a collection point in accordance with the law of waste electrical and electronic equipment.
Before the equipment is sent to a collection point, do not dismantle any elements. Observe the local regulations concerning disposal of packages.
