7.1.2 Recording PEAK values

From MENU the following modes are available:

PEAK – displays the peak value of the measured, if it lasts more
than 1 ms.

CF (Crest Factor) – crest factor signal according to the following
formula:
where:
– peak value
X
max
– RMS value

sk

7.1.3 Relative measurement - REL

This mode enables a measurement relative to a stored reference value.
The displayed main result is the difference between the reference value (read-out at the moment of
activating REL mode) and the current read-out. Example: if the reference value is 20 A, and the cur-
rent reading is 12.5 A, then the main result on the display will be -7.5 A. If the new reading is identical
to the reference value, then the result will be zero.

From MENU select REL mode,

Current readings are presented as a deviation relative to the reference value

Use F3 to switch between reference units:
 unit of the selected measurement function
 %.

7.1.4 Mode: Hz,%,ms

This mode displays the frequency of the pulse filling indicator.

From MENU select mode: Hz,%,ms,

Use F1 F2 buttons to select:
 Hz,% displays the frequency and pulse filling indicator in %
 ms
displays frequency and pulse width in ms
