The device proposes three measurement speeds and two measurement configurations on ca-
pacitive circuits:
➢
NORMAL
: 5 measurements are averaged for each display with 3 displays per second
➢
SLOW
: 15 measurements are averaged for each display with 1 display per second.
➢
FAST
: 1 measurement for each display with 10 displays per second.
➢
CABLE
and
CAPACITOR
: these measurement modes have the same speed character-
istics as in normal mode but they make use of analogue and software processing in order
to allow for stable measurements on highly capacitive circuits.
o
In both
CABLE
and
CAPACITOR
modes the measurement range will be limited
from 0.010 nA to 20.00 mA
o
Selection of the
CABLE
or
CAPACITOR
modes is indicated by a cable reel or a
capacitor symbol in the main measurement window left hand side corner.

o
The
CABLE
mode is more particularly intended for capacitance measurements
in disturbed environments (cable reels, machines in workshops, etc.).
o
The
CAPACITOR
mode is intended for measurements on capacitive compo-
nents in the laboratory environment. In this mode, the automatic searching
range function will start from the 20mA to the 2nA ranges but it will not go back
unless a short-circuit on the high voltage generator output. It is mandatory to
go in discharge mode by pressing the STOP button before disconnecting th e
DUT.
