Measurement Of Ac Intensity; Measurement Of Voltage; Measurement Of Max Value - Chauvin Arnoux F11N Manual De Funcionamiento

5. MEASUREMENT OF AC INTENSITY

 Set the switch to the A AC function : automatic selection
of the 2 ranges.
 Press the trigger to open the jaws of the clamp and
enclose a single conductor.
 Record the measurement, if necessary, by pressing
one of the HOLD keys.
 Display the max. value, if necessary, by pressing the
MAX key.
The F11N clamp measures the average value and
displays the rms value (only for a sinusoidal current).
The measurement will be false if the current is
distorted (non sinusoidal).
The F13N, on the other hand, gives the rms value
whatever the current : distorted or sinusoidal.
At approximately 400A and above, there may be
slight vibration of the jaws, but this does not affect
the measurement in any way.

6. MEASUREMENT OF VOLTAGE

 Set the switch to the required V ~ or V ... function :
automatic selection of the 2 ranges.
 Connect the red lead to the + terminal and the black
lead to the COM terminal and then connect up to the
element to be measured.
 Record the measurement, if necessary, by pressing
one of the HOLD keys.
 Display the max. value, if necessary, by pressing the
MAX button.
The F13N gives the rms value whatever the voltage:
distorted or sinusoidal.

7. MEASUREMENT OF MAX VALUE

 Set the switch to the A~, V~ or V ... function.
 Press the MAX key.
 Proceed in the same way as for intensity or voltage
measurements.
 The MAX positive value is displayed.
