The current clamp C-Probe 1 was designed as current/potential transformer
especially for the exact measurement of broadband currents.
Figure 4-1:
Current clamp C-Probe 1
C-Probe 1 is equipped with a Hall probe that can be used to measure both
alternating and direct current potential free without the need to interfere with
the circuit to be measured.
The current measurement range reaches from 50 mA up to 80 A (AC and
DC).
The current clamp contains two measurement ranges: 10 mV/A and
100 mV/A as well as two control lamps for
• power supply (ON) and
• measurement range exceeding (OL = Overload).
A thumbwheel is provided to precisely adjust the zero point. That way the
current clamp can be correctly adjusted to its specific measuring
environment (refer to section 5.1 “Zero Adjustment” on page 19).
The current clamp can be connected to any measuring device with an input
impedance of at least 100 k Ohm.
