lektor January & February 2021 87(1d) allows you to select the standardized
value in this series.
> Sort (1e)
This menu starts the comparison, with the
display of the measured value (top), the
upper and lower limits, and of course if the
test PASSes or FAILs.
> AC level (1f)
This menu selects the amplitude of the test
signal without load. Possible values are:
100 mV 200 mV 500 mV 1 V (RMS)
> DC bias (1g/h)
This menu adjusts the value of the voltage
(for capacitor) or current (for inductance) of
DC bias. Possible values are:- 0 to 5.0 V, in 1 V or 0.1 V steps
- 0 to 50 mA in 10 mA or 1 mA steps
Pressing the rotary button changes the value
of the step.User Menu (Figure 1)
> Language (1a)
Selection of the language used for the menus.
The current version supports English, French,
German and Dutch.
> Q limit for secondary display (1b)
Selecting the value of the Q (= 1/D) above
which the secondary setting is not displayed.
Possible values are:
100 200 500 1000 2000 5000 no limit
> Sorting parameters (1c)
This menu lets you select the parame-
ters (tolerance and value) used for sorting
components. The value proposed will be
that of the primary parameter of the refer-
ence component connected before going
into menu mode. These parameters will be
memorized. The first step (1c) allows you
to select the standard tolerance, from E6
(20%) to E96 (1%) series. The second stepa PC, but you still want to use it in stand-
alone mode, you’ll need to press the upper
button on the keypad while powering it up.
(The new mode is memorized and no further
action is required for the next start.) The
same action is needed for returning to the
PC mode. When the measurement screen
is displayed, the rotary button changes the
measuring frequency to one of 54 predefined
values (Table 1).
A long keypress on the rotary button allows
you to enter a user defined frequency. The
digit to be changed is selected using the top
two buttons, and the rotary button changes
its value. After validation, it is this value that is
used (it is displayed in negative) and cannot
be changed by the rotary button. A new long
keypress on the rotary button is required to
exit this mode. If the value is backed up, it will
be offered in the next request.
Button labels are displayed on the screen and
changed to the settings you choose. For some
buttons the action depends on whether they
are pressed short or longer. In the latter case,
the screen flashes briefly to signal that this
state is detected.
The first (upper) button switches
the component representa-
tion: From AUTO (default mode)
to SERIES or PARALLEL.
The second button [TRIM] initiates
the TRIM procedure for the current
frequency (OPEN or SHORT accord-
ing to the measured impedance). A long
press initiates the procedure of saving
all TRIM actions taken since the last start.
The third button [AVG S] or [AVG F ]
allows you to change the number of
measurements used (average) for the
display, and thus the responsiveness
of the instrument. It acts as a switch
between Slow display (Average SLOW
is displayed) and Fast display (Average
FAST is displayed). NOTE: This feature
is introduced from version 2.0.0 of the
firmware and most screenshots were
made before the software was updated!
The fourth button [R-HOLD] allows you
to toggle freezing the current range. A
long press toggles display of the meter’s
settings: the range (R1...R4), PGA gain in
voltage (Ux) and current measurement
(Ix) respectively (with x = 1, 3 or 10).
The last button [MENU]: Short keypress,
for access to the User Menu (measure-
ment parameters), a longer keypress
opens the calibration Menu.
