1. User instructions
This operating manual is intended for
- skilled electricians and
- electrotechnically trained personnel.
The BENNING CM 9-1 is intended for making measurements in dry environ-
ment. It must not be used in power circuits with a nominal voltage higher than
CAT IV 300 V or CAT III 600 V (More details in Section 6. “Ambient conditions”).
The following symbols are used in this operating manual and on the BENNING
CM 9-1:
Application around and removal from HAZARDOUS LIVE conductors
is permitted.
Warning of electrical danger!
Indicates instructions which must be followed to avoid danger to per-
sons.
Attention! Must comply with documentation!
This symbol indicates that the information provided in the operating
manual must be complied with in order to avoid risks.
CAT III
Measuring category III is applicable to testing and measuring circuits
connected to the distribution circuit of the low-voltage mains installa-
tion of a building.
CAT IV
Measuring category IV is applicable to testing and measuring circuits
connected to the feed-in point of the low-voltage mains installation
of a building.
Do not use the device in external low-frequency magnetic fields with
more than 30 A/m.
This symbol on the BENNING CM 9-1 indicates that the BENNING
CM 9-1 is equipped with protective insulation (protection class II).
Please observe the operating manual!
This symbol appears on the display to indicate a discharged battery.
This symbol designates the „continuity test“ field. The buzzer is in
-
tended for acoustic result output.
(DC) Direct voltage
(AC) Alternating voltage or current
Ground (voltage against ground)
