Capacity Measurement - Benning CM 12 Bedienungsanleitung

8.3 Resistance measurements
- Select the desired function
BENNING CM 12.
- Connect the black safety measuring lead to the COM socket O on the
BENNING CM 12.
- Connect the red safety measuring lead to the socket + P on the
BENNING CM 12.
- Connect the safety measuring leads to the measuring points. Read the
measurement value displayed in the digital display J .
See figure 5:
8.4 Diode tests
- Select the desired function
BENNING CM 12.
- Connect the black safety measuring lead to the COM socket O on the
BENNING CM 12.
- Connect the red safety measuring lead to the socket + P on the
BENNING CM 12.
- Connect the safety measuring leads to the measuring points. Read the
measurement value displayed in the digital display J .
- For a standard Si diode applied in conduction direction, a conduction voltage
between 0.40 V and 0.80 V is displayed. "OL" indicates an interruption and
"bAd" indicates a short-circuit inside the diode.
- For a diode applied in reverse direction, a negative forward voltage between
-0.40 V and -0.80 V is indicated.
See figure 5:
8.5 Continuity test with buzzer
- Select the desired function
BENNING CM 12.
- Connect the black safety measuring lead to the COM socket O on the
BENNING CM 12.
- Connect the red safety measuring lead to the socket + P on the
BENNING CM 12.
- Connect the safety measuring leads to the measuring points. If the line resis-
tance between the COM jack O and the jack + P falls below the adjustable
limiting value (30 Ω to 100 Ω), the integrated buzzer of the BENNING CM 12
sounds and the red LED 3 lights up.
See figure 5:

8.6 Capacity 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!
- Select the desired function
BENNING CM 12.
- Determine the polarity of the capacitor and discharge capacitor completely.
- Connect the black safety measuring lead to the COM socket O on the
BENNING CM 12.
- Connect the red safety measuring lead to the socket + P on the
BENNING CM 12.
- Contact the discharged capacitor with the safety measuring leads observing
correct polarity. Read the measurement value on the digital display J of the
BENNING CM 12.
See figure 6:
8.7 Frequency measurement
