BENNING MM P3
27
8.5 Continuity test with buzzer
- Select the desired function
(Ω,
, ) by means of the rotary switch
7
of the
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.
See figure 6:
Continuity test with buzzer
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 (
) by means of the rotary switch
7
of the
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 (
)“ key
6
.
- 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.
See figure 7:
Capacity measurement
8.7 Frequency measurement
- In order to measure square wave signals of up to 5 V
SS
, select the desired
function (Hz, %) by means of the rotary switch
7
.
- In order to measure sinusoidal signals of up to 600 V
eff
, select the desired function
(V
AC
, Hz, %) by means of the rotary switch
7
and switch over to frequency
measurement (Hz) by means of the „SELECT“ key.
- Please observe the minimum sensitivity for frequency measurements of the
BENNING MM P3!
- Bring the safety measuring lines into contact with the measuring
points and read the measured value on the digital display
of the
BENNING MM P3.
See figure 8:
Frequency/ pulse duty factor measurement
8.8 Pulse-Duty Factor Measurement
- Select the desired function (Hz, %) at the BENNING MM P3 by means of the
rotary switch
7
.
- Switch over to the pulse-duty factor measurement (%) 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 and read
the measured value on the digital display
of the BENNING MM P3.
See figure 8:
