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 sa-
ved in non-volatile memory (see the description
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 save
the measurement value in memory A, B or

the settings in the confi guration 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 respectively
the keys and . Allows saving the current
settings confi guration 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
fl eetingly displayed at every press of the key to
indicate the new range. A long press on this key
