Control elements

Digital display (7-segment LeDs)
The measurement value is displayed with a
resolution of 5 digit.The most adapted unit is
displayed in the area
cation is displayed by -----.
FReQUeNCY (pushbutton)
Measuring frequency selection:
100 Hz, 120 Hz, 1 kHz, 10 kHz, 25 kHz
A (pushbutton) and -A (LeD)
Allows to save the current measurement value
in memory (volatile memory) of the instrument
if the instrument is in storage mode (SToRE
LED is on). The measurement value can be
saved in non-volatile memory (see the de-
scription of the CAL button). In relative mode
(-A LED is on), the instrument displays the
relative value Measurement-A , or, if the -A and
÷B LED are on, 100* (Measurement-A)/B . The
relative mode is left by pushing the button A
again.
StORe (pushbutton)
By depressing this key the LED indicator
located above it lights up and the instrument
is in storage mode. Then you can press the
following keys A, B or CoNFIG in order to
20
Subject to change without notice
. Any overflow indi-
save the measurement value in memory A, B
or the settings in the configuration memory.
The display will shortly show STO. A, STO. B
or STO.C.If you press any other key the storage
mode will be left. The LED Indicator turns off
in both cases.
B (pushbutton) and ÷B (LeD)
In storage mode (SToRE LED lights) the
current measurement value will be stored in
memory B (volatile memory) if the button B is
pushed. The measurement value can be saved
in non-volatile memory (see the description of
the CAL button). In relative mode (LED ÷B is on)
the instrument displays the percentage 100*
Measurement/B or 100* (Measurement-A)/B
if the LEDs -A and ÷B are active. The relative
mode is left by pushing the button B again.
CAL (pushbutton)
In normal mode, this button allows to perform
open/Short circuit calibration with respec-
tively the keys and
current settings configuration in non-volatile
memory if the instrument is in storage mode
(STORE LED lighted up).
RANGe/AUtO* (pushbutton)
In manual mode (AUTo LED is off) this key
allows to select the impedance range of the
instrument. A message RNG. X (X = 1...6) is
fleetingly displayed at every press of the key to
. Allows saving the
