Liquid Crystal Display (LCD)
4.1
Digital Display
The main digital display shows the measured value, decimal
point and sign. The selected measuring unit and function are

of the digits, when the positive pole of the measured quantity is
applied to the „ “ input terminal.
„
OL
“ is displayed if the measuring range upper limit is
exceeded.
The digital display is updated three times per second for V, A,
Ω
, Cap., Freq. and duty cycle measurements.
