5. MEASUREMENT OF AC INTENSITY<br />
■<br />
■<br />
■<br />
■<br />
Set the switch to the A AC function: automatic selection<br />
of the 2 ranges.<br />
Press the trigger to open the jaws of the clamp and enclose<br />
a single conductor.<br />
Record the measurement, if necessary, by pressing one<br />
of the HOLD keys.<br />
Display the max. value, if necessary, by pressing the MAX<br />
key.<br />
The <strong>F11N</strong> clamp measures the average value and<br />
displays the rms value (only for a sinusoidal current).<br />
The measurement will be false if the current is distorted<br />
(non sinusoidal).<br />
La <strong>F13N</strong>, on the other hand, gives the rms value<br />
whatever the current : distorted or sinusoidal.<br />
At approximately 400 A and above, there may be slight<br />
vibration of the jaws, but this does not affect the<br />
measurement in any way.<br />
6. MEASUREMENT OF VOLTAGE<br />
■<br />
■<br />
■<br />
■<br />
Set the switch to the required V AC or V DC function:<br />
automatic selection of the 2 ranges.<br />
Connect the red lead to the + terminal and the black lead<br />
to the VOM terminal and then connect up to the element<br />
to be measured.<br />
Record the measurement, if necessary, by pressing one<br />
of the HOLD keys.<br />
Display the max value, if necessary, by pressing the MAX<br />
button.<br />
The <strong>F13N</strong> gives the rms value whatever the voltage :<br />
distorted or sinusoidal.<br />
7. MEASUREMENT OF MAX VALUE<br />
■<br />
■<br />
■<br />
■<br />
Set the switch to the A~, V~ or V ... function.<br />
Press the MAX key.<br />
Proceed in the same way as for intensity or voltage<br />
measurements.<br />
The MAX positive value is displayed.<br />
