3.5.1 LCD
Consisting of:
R
Analog display (42 segments), displays the current
measured value
R
Digital display (display range, 3999), the display

measurement mode (selected by means of measure-
ment-mode switch and function button)
3.5.2 Blue function button
Depending on the position of the measurement-mode
switch, pressing this function button switches between:
R
Continuity test and resistance measure- ment
R
Capacitance measurement and diode test
R
Frequency measurement
R
Direct and alternating current measurement
3.5.3 MIN MAX button
R
The minimum memory is activated by pressing the
button once (the smallest measured value is saved
and displayed).
R
The maximum memory is activated by pressing the
button again or twice (the greatest measured value

indicates whether the minimum or maximum memo-
ry respectively has been activated.
R
The analog display always indicates the current
measured value.
R
Measurement is "frozen" by pressing the HOLD but-
ton (fig. 1, pos. 5). Measurement resumes by press-
ing the button again.
R
You leave the MIN./MAX. mode by pressing the
RANGE-button (fig. 1, pos. 7) for approx. 2 seconds.
3.5.4 REL ∆-button
R
By pressing the button once, the current measured
value is saved and the digital display is set to 0000.
REL appears in the display. The value now displayed
represents the differential between the measured
and saved values.
R
The analog display always shows the current mea-
sured value.
R
You can exit the REL -∆ mode by pressing the RANGE-
button (fig. 1, pos. 7) for approx. 2 seconds.
