8.4 Diode test
- Select the desired function (
teStFOX M/ M-1.
- Connect the black safety measuring line to the COM jack J of the
teStFOX M/ M-1.
- Connect the red safety measuring line to the jack for V, ,
teStFOX M/ M-1.
- Bring the safety measuring lines into contact with the diode connections
and read the measured value on the digital display  of the
teStFOX M/ M-1.
- For a standard Si diode applied in conduction direction, a conduction voltage
between 0.400 V and 0.900 V is displayed. „000" indicates a short-circuit
inside the diode, „Ol" indicates an interruption inside the diode.
- For a diode applied in reverse direction, „Ol" is indicated. if the diode is
defective, „000" or other values are indicated.
See figure 7:
8.5 Continuity test with buzzer
- Select the desired function (
teStFOX M/ M-1.

teStFOX M/ M-1.
- Connect the red safety measuring line to the jack for V, ,
teStFOX M/ M-1.
- Bring the safety measuring lines into contact with the measuring points. if the
line resistance between the COM jack J and the jack for V, ,
below 25 , the integrated buzzer of the teStFOX M/ M-1 sounds.
See figure 8:
8.6 Capacity measurement ( TESTFOX M-1)
Before performing capacity measurements, discharge capaci-
tors completely!

Never apply voltage to the capacity measurement jacks!
This might damage or destroy the device! A damaged device
might represent an electrical hazard!
