5.16 External Clamp Adaptor Current Measurements
Note: This section applies only to measurements taken with an external clamp
adaptor that connects to the CM65 input terminal jacks. For clamp measure-
ments using the CM65’s built-in clamp jaws, please see Section 5.11,
Current
Measurements (Clamp) .
Figure 5.9 External Clamp Adaptor Test Setup
1. Set the CM65 function switch to the external clamp adaptor position .
2. Connect the external clamp adaptor to the CM65 by inserting the signal
leads from the external clamp to the input terminals on the CM65, observ-
ing correct polarity.
3. Press the trigger to open the clamp jaws on the external clamp adaptor
and clamp around the conductor under test.
4. Read the measurement on the CM65 display. See Section 12.15, External
Clamp Adaptor (AC Current) , to help interpret the reading based on the
range of the measurement . As an example, in some ranges, for each
100mV sent to the CM65 by the external clamp adaptor, the CM65 dis-
plays 1 ampere (100mV/A).
5. The available Function Icons in this mode are Settings and MIN/MAX/AVG.
