Description
The arrow located on the closure unit indicates the direction of current flow.
The current is assumed to flow in the positive direction if it flows from the
source to the receiver. Such a test direction is required for correct power
measurement.
The output signal is provided by a 2.5 meter long lead with a pin adapted to
the socket in the meter.
F-xA coil
Flexible coils F-1A, F-2A and F-3 (Rogowski coil) are used to measure
alternating current in the range from 40 Hz to 20 kHz and current up to 3000 A
(10 kHz peak at 50 Hz)
The only difference between The flexible coils F-1A, F-2A and F-3A is the size
of the coil. The electrical parameters are the same.
The output signal if the voltage is proportional to the derivative of the
measured current, where the sensitivity is 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 with
double increased sensitivity compared to F-1A/F-2A/F-3A, which translates into
a halved measurement range for current up to 1500 A
output signal is a voltage proportional to the current derivative measured
with a sensitivity of 77.66 mV/1000 A for 50 Hz and 93.19 mV/1000 A for 60 Hz
Coil F-xA6 coil
Flexible probes (Rogowski coil) F-1A6, F-2A6 and F-3A6 are clamps of double
reduced sensitivity compared to F-1A/F-2A/F-3A, which translates into double
measurement range for current up to 6000 A.
Signal The output is a voltage proportional to the current derivative measured
with a sensitivity of 19.415 mV/1000 A for 50 Hz and 23.3 mV/1000 A for 60 Hz
safety
NOTE!
Non-insulated coils must not be used for conductors with a potential exceeding
1000 V with respect to earth, in systems with measurement category higher than
III and systems of measurement category IV with a potential exceeding 600 V.
Operation
To measure the current, open the coil slightly by turning the clamp, clamp
them on the conductor with a flowing current and center the conductor
approximately with respect to the loop of the coil. Pay attention to the
direction of the arrow, to avoid power measurement error.
NOTE!
Follow the instructions for mechanical limitations of the coils. Mechanical
damage to the coil is not covered by the warranty.

damage to the coil is not covered by the warranty.
Do not pull with force
Do not forcefully bend
Do not pack in a bent position
Cleaning and maintenance
**NOTE!**
Apply only maintenance methods specified by the manufacturer in this manual.
Apply only maintenance methods specified by the manufacturer in this manual.
Before cleaning, disconnect the coil from the circuit under test and the
meter.
The reel can be cleaned with a soft, damp cloth using all-purpose cleaners. Do
not use any solvents.
Dismantling and utilization
Used electrical and electronic equipment must be collected selectively, i.e.
it must not be placed with other types of waste.
Worn electrical equipment must be sent to a collection point in accordance
with the Electrical and Electronic Equipment Waste Law.
Before sending the equipment to a collection point, do not disassemble any
elements. Pay attention to local regulations regarding packaging disposal.
