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