4.2 Symbols Used in the Digital Display
1 Momentary measuring function
2 Memory symbol
3 Important, in this case: Uext (interference voltage) or
warning regarding dangerous voltage: U > 15 V AC or U > 25 V DC
4 Battery pack charge level (see page 10)
5 Func: switch back and forth amongst the functions of a given rotary
switch position
6 Data MinMax: switch amongst “Data” (freeze measured value), “Min-Max
storage” and deactivate both functions
7 Man Auto: switch back and forth between manual and automatic measur-
ing range selection
8 Display of the selected measuring range with manual measuring range
selection:
Select a lower measuring range
Select a higher measuring range
9 Selected test voltage
10 Select test voltage:
Select a larger test voltage
Select a smaller test voltage
11 Digital display with decimal point and polarity display
Measuring range exceeded: OL is displayed
12 Scale for analog display
13 Polarity selection
14 Zero: Zero balancing active
15 Start/Stop: For measurements which are not started automatically
16 Ip: test current
