8. ON The K1 and 2 current probes enable the measurement of low 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 3 1 100 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 2 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 manipul
