8. Measuring by means of the BENNING MM P3
8.1 Preparing the measurement
Operate and store the BENNING MM P3 at the specified storage and operating
temperatures only!
Do not permanently expose the device to sunlight.
- The connected black and red safety measuring lines comply with the valid
provision, if they are undamaged.
- Please protect the connected black and red safety measuring lines against
contamination and damages!
- Check insulation of the safety measuring lines. If the insulation is damaged,
multimeter must be replaced immediately.
- Check the safety measuring lines for continuity. If the conductor in the safety
measuring line is interrupted, replace the multimeter immediately.
- Before selecting another function by means of the rotary switch 7, disconnect
the safety measuring lines from the measuring point.
- Strong sources of interference in the vicinity of the BENNING MM P3 might involve
unstable readings and measuring errors.
