See gure 2: DC voltage measurement
See gure 3: AC voltage measurement
8.2.2 Current measurement ( TESTFOX M-1)
- Select the desired range and function (A AC) or (A DC) by means of the
rotary switch 8 of the TESTFOX M-1.
- Connect the black safety measuring line to the COM jack J of the
TESTFOX M-1.
- Connect the red safety measuring line to the jack for V, , , Hz 9 or
to the jack for the 10 A range K (DC or AC currents up to 10 A) of the
TESTFOX M-1.
- Bring the safety measuring lines into contact with the measuring
points and read the measured value on the digital display  of the
TESTFOX M-1.
See gure 4: DC current measurement ( TESTFOX M-1)
See gure 5: AC current measurement ( TESTFOX M-1)
8.3 Resistance measurement
- Select the desired function (Ω) by means of the rotary switch 8 of the
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, , , Hz 9 of the
TESTFOX M/ M-1.
- Bring the safety measuring lines into contact with the measuring
points and read the measured value on the digital display  of the
TESTFOX M/ M-1.
See gure 6: Resistance measurement
8.4 Diode test
- Select the desired function ( ) by means of the rotary switch 8 of the
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, , , Hz 9 of the
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 gure 7: Diode test
8.5 Continuity test with buzzer
- Select the desired function ( ) by means of the rotary switch 8 of the
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, , , Hz 9 of the
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, , , Hz 9 falls
below 25 , the integrated buzzer of the TESTFOX M/ M-1 sounds.

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!
- Select the desired function ( ) by means of the rotary switch 8 of the
TESTFOX M-1.
