5.1 Digital Display
The main digital display (10) shows the measured value with
correct location of decimal point and sign. The selected mea-
suring unit (15) and the function (21) are simultaneously dis-
played. When measuring DC quantities, a minus sign appears
in front of the digits, when the positive pole of the measured
quantity is applied to the „ “ input terminal. When upper range
limit 6600 (on the range :1999) is exceeded, „OL“ is dis-
played. The digital display is updated 2.8 times per second.
The digital sub-display (14) shows the measured value with
