8.5 Continuity test with buzzer
- Select the desired function (Ω,
BENNING MM P3.
- Switch over to the continuity test ( ) by means of the „SELECT" key 5 of the
BENNING MM P3 (press the key once).
- Bring the safety measuring lines into contact with the measuring points.
- If the resistance between the measuring points falls below 50 Ω, the integrated
buzzer of the BENNING MM P3 sounds.

8.6 Capacity measurement
Before performing capacity measurements, discharge capacitors com-
pletely!

Never apply voltage to the capacity measurement jacks!
This might damage or destroy the device! A damaged device might
represent an electrical hazard!
- Select the desired function (
BENNING MM P3.
- Determine the polarity of the capacitor and completely discharge the capacitor.
- If necessary, make the null balance by means of the „RANGE/ REL Δ (
- Bring the safety measuring lines into contact with the discharged capacitor
according to ist polarity and read the measured value on the digital display  of
the BENNING MM P3.
