Diode Testing; Continuity Testing; Frequency Ranges - Benning MM 12 Bedienungsanleitung

Additional specifications:
The measured value is obtained and displayed as a true effective value (TRUE RMS). Selectable
coupling type: AC or AC+DC. For the coupling AC+DC an additional error of 1 % must be taken
into account. In the case of non-sinus-shaped curves the display value becomes less precise.
Thus an additional error results for the following crest factors:
Crest factor from 1.4 to 2.0 additional errors + 1.0 %
Crest factor from 2.0 to 2.5 additional errors + 2.5 %
Crest factor from 2.5 to 3.0 additional errors + 4.0 %
HFR high-frequency suppression (low-pass filter):
AC accuracy plus 1 % of the measured value, 40 Hz to 400 Hz
Limiting frequency (- 3 dB): 800 Hz
Attenuation: approx. - 24 dB
Peak-Hold: ± 3 % of the measured value + 200 digits, 40 Hz to 1 kHz, sinusoidal
