Maximum measurement duration is 15 s
7
Frequency measurement as separate function
8
Below 2 Hz the display shows 0 Hz
9
Frequency measurement is not specified for alternating currents or
voltages below 3% of the smallest respective measuring range
10
The lower measuring ranges are only specified from 5%
11
Signal bandwidth 40 Hz to 1 kHz
12
In the case of a mixed signal (AC + DC), only the purely AC component is
taken into account
13
As the frequency increases (over 400 Hz), the accuracy deteriorates
