The measured value is obtained by mean value rectification and is displayed
*1
as r.m.s. value. Its calibration is adapted to a sinusoidal curve.
The stated accuracy is specified for conductors that are centrally clamped
by means of the current clamp L (see figure 4 AC current measurement).
For conductors that are not centrally clamped, an additional error of 1 % of
the displayed value has to be considered.

8. Measuring by means of the TESTFOX CC
8.1 Preparing the measurement
Operate and store the TESTFOX CC 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 CC.
- 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 sliding switch 7,
disconnect the safety measuring lines from the measuring point.
- Strong sources of interference in the vicinity of the TESTFOX CC might
involve unstable readings and measuring errors.
