This is what the automatic polarity indication for DC current and voltage refers to
5. General information
5.1 General details on the multimeter
5.1.1 The digital display is a 3 ¾ or 4 ½ digit liquid crystal display with a
13 mm font size and decimal point. The largest display value is 4.000/
20.000.
5.1.2 The bar graph display comprises 42 segments.
5.1.3 The polarity indication is automatic. Only one polarity with respect to
the socket marked “-” is indicated.
5.1.4 The overranging is indicated by “0L” or “- 0L” and, in part, an acoustic
warning.
Warning, no indication and prior warning in the event of an overload
condition! A exceeding of dangerous contact voltage (> 60 V DC/ 30 V
AC rms) is indicated by an additional flashing symbol “”.
5.1.5 The 01 confirms each button press with a signal sound.
Invalid button presses are confirmed by a double signal sound.
In the event of an incorrect circuit of the jack for the mA / A range
the 01 warns with a signal sound and the indication
of in the display .
The acoustic alarm and the indication in the display extinguish
if a safety measuring cable is plugged into the jack for the mA or
A range and the corresponding current measurement range was
selected by means of the rotary switch .
The acoustic alarm and the indication in the display also appear
in the case of a defective fuse, if the safety measuring cable is plugged
into the jack for the mA or A-range and the corresponding current
measurement range was selected by means of the rotary switch .
5.1.6 The 01 features individual setting options which in part
remain active even after a shutdown. In order to change a setting,
press one of the following buttons and simultaneously activate the
01 from its “OFF” switch position.
Button- : Deactivates/ activates the automatic shutdown of the
background lighting after 15 minutes.
Button- 7:
Presetting of the nominal mains frequency (50 Hz or
60 Hz). This adjustment ensures improved stability
and accuracy in AC V mode. These settings are main-
tained even after the 01 is switched off.
The settings are modified only after a new presetting!
Button- :Presetting the temperature measurement in °C or °F.
The settings are modified only after a new presetting!
Button-BLUE : Deactivates/ activates the automatic switch-off after
approx. 30 minutes (APO, Auto-Power-Off).
Button- :Deletion of the internal measuring value memory (see
also Chapter 5.2)
Button- :Deactivates/ activates the fitted buzzer.
5.1.7 The button (yellow) switches on the display illumination. Shutdown
is effected by a renewed press of the button or automatically after 15
mins.
