g) V/Ω-Socket
For measurement of voltage, frequency, resistance, continuity, diodes
and logic tests plug in the red test-lead in this terminal.
4.3.4 Display Explanation and Symbols
a) Digital Display
Digital readings are displayed the main- and the sub-displays (small
displays) on a 19999-count basis with automatic polarity indication (-),
(for negative voltage or reversed polarity). There are four decimal
point positions.
b) Analogous Bargraph
The bargraph consists of 43 segments and is faster than the digital
display. It functions like the needle of an analogous measuring instru-
ment, but without its mechanical disadvantages. Is is especially for
quick changing measuring signal, for which the digital display is too
"slow". So you can quickly see tendencies in the measuring values.
If the measuring range is exceeded "OL" for Overload is displayed the
bargraph is flashing and a warning sound sound is emitted (no acou-
stic signal during measurement of resistance, diode, temperature -
"OL" without thermo-element).
c) Data-Hold "D-H"
In this mode you can freeze a reading in the second ("small") display
by pressing the SET/R button. To exit this subfunction hold down
SET/R button or FUNC for a few seconds or turn the function selector
switch (observe the safety rules). Afterwards you return to the basic
setting.
d) Auto Hold A-H
In this function the meter will automatically record the minimum and
the maximum display reading, MIN and MAX values. These values are
currently updated = refreshed. The MIN-value is shown on the left
sub-display, the MAX-value on the right sub-display. On the middle
sub-display the average value = AVG is shown. This value is currently
"refreshed".
To exit this function mode press SET/R again or press FUNC or turn the
rotary function switch (observe the safety rules!), afterwards return
to normal settings.

e) REL (= Relative)
The relative mode enables the operator to compare the reference
value with a subsequent reading. Proceed as follows:
- Set the function mode at REL mode and press once the button SET/R
- Store the polarity by pressing the UP and DOWN keys, afterward press
SET/R button.
- Press UP and DOWN buttons again to set the desired reference value.
Press SET/R by turns to move to the next digit.
- For final setting of the reference value press SET/R button once again.
- The meter will now display the difference between the stored refe-
rence value and the subsequent readings on the sub-displays, while
the present (true) measurement is on the main-display. The left sub-
display will show the difference in %, the middle sub-display will
show the offset and the right sub-display the preset reference.
To exit this function mode press SET/R again or press FUNC or turn the
rotary function switch (observe the safety rules!), afterwards return
to normal settings.
f) MEM (= Memory)
Up to 10 measurements (reference number 0 to 9) can be stored and
recalled. Proceed as follows:
1. Push function button until MEM flashes in the display, afterwards
press the key SET/R once. MEM is fixed and the reference number flas-
hes. Make your measurements and push the SET/R key once to store
the present measurement value in the first free memory location =
reference no. 0.
2. Press UP/DOWN button to go to the next free memory location (refe-
rence no. between 0 and 9).
Make again your measurement and push the key SET/R once. This sel-
ected memory now is addressed. If a memory number which has been
used before is selcted, the previous value is updated and stored with
the new measurement value.To exit this function mode turn the fun-
ction switch (observe the safety rules!) or press the buttons FUNC or
SET/R.
