Theoretical Sample of Charging Field
N UMBER D IGITS
Number Digits allows the selection of the number of digits, either three or four,
to be displayed.
AVG M ODE
AVG Mode allows the selection between MEAN and RMS (root mean square).
• Mean is the average of the observed values from the beginning of the
averaging interval.
• RMS refers to the square root of the mean of the squared value of a
function. The RMS average field intensity value is proportional to the
power density of the field. When logging in power density units, the
RMS and mean values are equal.
For more information on averaging see Averaging on page 38.
