Capacitance Measurement - Benning MM 7-1 Instrucciones De Servicio

- Connect the black safety measuring lead to the COM socket  on the
BENNING MM 7-1.
- Connect the red safety measuring lead to the socket  for V, Ω, Hz, ,
on the BENNING MM 7-1.
- Contact the diode connections with the safety measuring leads and
read the measurement value displayed in the digital display  of the
BENNING MM 7-1.
- For a normal silicone diode located in flow direction, the flow voltage
between 0.4 V and 0.8 V is displayed. If "000" appears in the display, there
may be a short circuit in the diode.
- If no forward voltage is detected, first check the polarity of the diode. If still
no forward voltage is displayed, the forward voltage of the diode is beyond
the measuring limits.
See fig. 7:
8.5 Continuity testing with buzzer
- With the rotating switch  , select the desired function ( ,
BENNING MM 7-1.
- Connect the black safety measuring lead to the COM socket  on the
BENNING MM 7-1.
- Connect the red safety measuring lead to the socket  for V, , Hz, ,
on the BENNING MM 7-1.
- Contact the measuring points with the safety measuring leads. If the meas-
uring lead resistance between the COM socket  and the socket  for V,
, Hz, ,
built-in buzzer is activated.

8.6 Capacitance measurement

Discharge capacitors fully before measurement! Never apply

voltage to the sockets for capacitance measurement as this
may cause irreparable damage to the unit. A damaged unit may
represent an electrical hazard!
- With the rotating switch  , select the desired function (
BENNING MM 7-1.
- Press the blue key  to switch over to the capacity measurement function.
- Determine the polarity of the capacitor and discharge it completely.
- Connect the black safety measuring lead to the COM socket  on the
BENNING MM 7-1.
- Connect the red safety measuring lead to the socket  for V, , Hz, ,
on the BENNING MM 7-1.
- Contact the discharged capacitor with the safety measuring leads observing
correct polarity. Read the measurement value on the digital display  of the
BENNING MM 7-1.
See fig. 9:
8.7 Frequency measurement
- With the rotating switch  , select the desired function ( Hz,
on the BENNING MM 7-1.
- Press the blue key  to switch over to the frequency measurement func-
tion.
- Connect the black safety measuring lead to the COM socket  on the
BENNING MM 7-1.
- For frequency measurement in the voltage range
measuring lead to the jack for V, , Hz, ,
- For frequency measurement in the voltage range
red safety measuring lead to the A jack  or to the mA jack  of the
BENNING MM 7-1.
- Remember the minimum sensitivity for frequency measurements using the
BENNING MM 7-1!
- Contact the measuring points with the safety measuring leads and read the
measurement result on the digital display  on the BENNING MM 7-1.
See fig. 10:
8.8 Temperature measurement
