Conrad Electronic MS-9160 Notice D'emploi page 16

The red test lead must be plugged into this socket when voltage or
resistance measurements, continuity check or logic tests are per-
formed.
C.4 Explanation of display and symbols
a) Digital display
The display can show up to "3999" and the polarity (-) is automati-
cally displayed (for negative voltages and reversed polarity). Addi-
tionally there are three decimal point positions.
b) Analogue bar graph
The analogue bar graph consists of 43 segments. It has a higher
speed of measurement than the digital display. Measured value
trends are thus more easily recognised. If the measurement range is
exceeded, "OL", for Overload will be displayed and the display
"flashes" in warning.
c) Auto Hold and Dual Display "d"
The Auto Hold function is active for DC voltage, current, resistance,
and capacity (CAP) measurements and continuity test. The measu-
red value, visible in the "large" display 4 - 5 sec. beforehand, is dis-
played in the small display. The Auto Hold function itself is indica-
ted with the letter "A" in front of the small display. "d" for Dual
Display appears left in front of the small display, when an AC volta-
ge (ACV) or logic (LOGIC) measurement is carried out. The following
table shows which measurements / indications are possible:
Measuring function Main display
(Large display)
AC voltage AC voltage
Logic measurement Hi/Lo
d) Data-Hold "D-H"
With D-H a measured value is frozen (held).
e) MIN (= Minimum)
Press this button once: the smallest measured value is displayed on
the second-(DUAL)display, while measurements continue with the
"normal" display.
f) MAX (= Maximum)
30
Subdisplay
(Small display)
dB(m)
DC voltage
Press the Set/Reset button once: the highest measured value is now
displayed on the second display, while measurements continue with
the large display.
g) REL (= Relative)
This setting permits the comparison of a reference value with a sub-
sequent measured value. Proceed as follows:
1. First press the "Function" button until "REL" appears in the
display.
2. Now set the polarity of the reference value, the reference value
and the measurement range with the "UP" and "DOWN" but-
tons. After each input the SET/RESET button must be pressed
once in confirmation.
Button operation sequence:
=> Function => Display "REL" =>
=> Setting ± (with UP-/DOWN buttons)
=> Setting first position
=> Setting 2 nd position
=> Setting 3 rd position
=> Setting 4 th position
=> Setting the measurement range (no automatic range change)
=> SET/RESET =>
=> The small display displays the reference value
The measuring instrument will now show the difference between the
stored value and the subsequently-measured value on the small display,
while the actual value presently being measured can be read on the
large display.
Example:The reference value is 100.0 V; the present (large display) rea-
ding shows 90 V. On the small display the difference of
-10 V can be read. Should the next measured value be 100.0 V,
the differ. will be "0". The small display then reads 0000. The
display can display 3999 max.
Attention!
With the REL function, RESET using the SET/RESET button is not possi-
ble. To exit this function, press either the measurement function switch
or the FUNCTION button or one of the other buttons.
