1. PRESENTATION
The K1 and K2 current probes enable the measurement of low DC or AC currents, without
opening the circuit being worked on.They connect to a multimeter or any other instrument
that has a voltage input and output impedance ³1 MW£100 pF.
These probes measure on one hand, DC currents from 1 mA to 4.5 A for the K1 probe and
from 0.1 to 450 mA for the K2 probe, and on the other hand, sinusoidal AC currents from
1 mA to 3 A for the K1 probe and from 0.1 to 300 mA for the K2 probe.
These probes output the current measured in the form of a voltage that is the image of the
primary current, in form and amplitude.
They have a single 1 mV/mA range for the K1 and 10 mV/mA range for the K2.
Both are equipped with an On/Off switch, a zero reset thumbwheel and two light indicators,
one for overload, the other for the voltage of the battery power supply.
The probe is in the form of a small clamp with a clamping capacity of 3.9 mm diameter. It
is connected to an adapter case by a multiconductor attached lead, shielded and insulated,
length 1.5 m.
In this case are the electronics of the probe and the 9V battery power supply (type 6LR61,
6LF22 or NEDA 1604). The battery life is approximately 20 hours with an alkaline battery.
The measurement output is ensured by two male safety plugs Ø4 mm, standard 19 mm
spacing, attached to the case. This case plugs directly into the associated measurement
instrument and thus leaves the user’s hands free to manipulate the clamp.
2. DESCRIPTION
The K1 and K2 consist of a sensor linked to an adapter unit by an attached cable (see
diagram on the last page of the user manual).
Sensor :
➊Passage of conductor
➋Jaws
➌Hand-held part
➍Cable attached to the sensor/case
Adapter case :
➎Adjust zero DC thumbwheel
➏On/Off switch
➐Battery “ON”indicator
➑“OL”overload indicator
➒4 mm Ømeasurement output sockets

3. HOW TO USE
Do not use the K1 and K2 current probes on cables or conductors at a potential
in relation to the earth , greater than 300 V.
3.1. SWITCHING ON
Put the sliding switch ➏to the appropriate position (1 mV/mA for the K1 and 10 mV/mA for
the K2).Correct operation is shown by the green “ON”light ➐which indicates good battery
condition. If this indicator does not light, or goes out, it is necessary to change the battery
(see Ch. 5.1).
3.2. ADJUST ZERO DC
■Ensure that the jaws of the clamp are correctly closed and they do not enclose any
conductor.
■Plug the output connectors ➒of the adapter case of the probe into your measurement
instrument. Switch on the probe (see Ch. 3.1).
■Select the most sensitive voltage range of your measurement instrument.
■Press the DC zero thumbwheel ➎and at the same time rotate it to obtain zero on the
display.
3.3. MEASUREMENT
After having switched on the probe :
■Connect the measurement instrument with the appropriate voltage range and adjust
zero DC (refer to Ch.3.1. and 3.2. above).
■Enclosethe conductor to measurebetweenthe jaws➊of the clamp.The valuemeasured
is displayed directly on the associated instrument as a function of the input/output ratio
of the probe.
■To obtain the value of the current in the cable, apply to the value measured, the
appropriate conversion ratio, as a function of the voltage range selected on the
measurement instrument and the sensitivity of the clamp.
3.4. OVERLOAD INDICATION
The detection of overload or overrange of the range of the probe, is signalled by the red
coloured “OL”indicator ➑. This indicator lights up for a peak current greater than 4.5 A for
the K1 and 450 mA for the K2.
