-
These functions alternate when the function button marked with AC/DC is
pressed. The digital display indicates the current function.
AC-current measurement (AC) and DC-current measurement (DC)
-
These functions alternate when the function button marked with AC/DC is
pressed. The digital display indicates the current function.
Resistance measurement and continuity measurement with buzzer
-
These functions alternate when the function button marked with /
pressed. The digital display indicates the current function.
Digital display (liquid-crystal type) with following indications:
-
measurement reading with max. indication 3999
-
polarity indication
-
decimal point
-
symbol for discharged battery
-
type of voltage selected (AC or DC voltage)
-
type of current selected (AC or DC current)
-
the measurement value retained (hold function) or the automatically
retained peak measurement value (MAX function)
-
the measurement function selected by indication of the extended/non-
extended measurement units of current and resistance
-
selected continuity test with buzzer.
Function button AC/DC - /
"", "buzzer symbol".
-
For selection between measurement of DC voltage/current or AC voltage/
current or
-
Resistance measurement and continuity test.
HOLD/MAX button (hold function and automatic peak-value storage)
-
The first press of the button causes the currently indicated measurement
value to be held (indicated by "HOLD" in the digital display , no updating
of measurement value).
-
The second press of the button leads to continuous measurement.
-
Pressing the button (for 2 sec.) during switch-on initiates the peak-value
storage (MAX) function. A second press of the button does not lead to
continuous measurement.
-
The first press of the button causes the peak value during the switched-
on measuring time to be stored (indicated by "MAX" in the digital display
). For all ranges except continuity test. Switch back (continuous
