Note

60 mV range:

Thermovoltages occur in the event of temperature fluctua-

tion, which appear as additional voltage offset. It may be

necessary to repeat zero offsetting in order to achieve the

specified degree of accuracy.

Crest Factor Display

Crest factor is displayed for voltages in the V (AC+DC) function

along with the measured voltage value. The voltage value is mea-

sured simultaneously in a separate measuring circuit to this end,

and crest factor is displayed within a range of 1.0 to 11.0.

This value indicates the quality of the applied signal. The only pre-

requisite is a periodic signal with a valid frequency (see table).
