8. Measuring by means of the TESTFOX M/ M-1

8.1 Preparing the measurement

Operate and store the TESTFOX M/ M-1 at the specified storage and operating
temperatures only!
Do not permanently expose the device to sunlight.
- Check stated nominal voltage and nominal current on the safety measuring
lines. Nominal voltage and current of the enclosed safety measuring lines
comply with the respective values of the teStFOX M/ M-1.
- Check insulation of the safety measuring lines. if the insulation is damaged,
the safety measuring lines must be replaced immediately.
- Check the safety measuring lines for continuity. if the conductor in the
safety measuring line is interrupted, replace the safety measuring lines
immediately.
- Before selecting another function by means of the rotary switch 8,
disconnect the safety measuring lines from the measuring point.
- Strong sources of interference in the vicinity of the teStFOX M/ M-1 might
involve unstable readings and measuring errors.
8.2 Voltage and current measurement
Do not exceed the maximum permitted voltage with respect to

earth potential! Electrical danger!
the highest voltage which may be applied to the
- COM jack J
- jack for V, Ω,
- jack for the 10 A range K ( teStFOX M-1)
of the teStFOX M/ M-1 against ground is 1000 V.
Electrical danger!
Maximum circuit voltage for a measured current of 500 V! In

case of fuse triggering at values above 500 V, damages of the
device might be involved. A damaged device might represent
an electrical hazard!
8.2.1

Voltage measurement

- Select the desired function (V AC) or (V DC) 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.
