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 ≥ 1 MΩ ≤ 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 9 V 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 Ø 4 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.
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).
