1 Safety Precautions
General
• Carefully and completely read and adhere to these operating instructions.
The document can be found at http://www.gossenmetrawatt.com. Retain
this document for future reference.
• Carefully and completely read and adhere to the product documentation of
the combined products. Retain these documents for future reference.
• Observe and comply with all safety regulations which are applicable for
your work environment.
Handling
• The probe may only be used as long as it is fully intact.
Inspect all cables and the probe before use. Pay particular attention to
damage, broken insulation or kinked cables.
• If the probe doesn’t function flawlessly, remove it from operation and
secure it against inadvertent use.
• If the probe is damaged during use, e.g. through falling, remove it from
operation and secure it against inadvertent use.
• If the equipment is used in a manner not specified in this reference guide,
the protection provided by the equipment may be impaired. These safety
precautions are repeated where appropriate throughout this manual.
Operating conditions
• Only use the probe in conjunction with the measuring device MAVOWATT
210.
• Only use the probe in compliance with the specified technical data and
under the specified conditions (ambient conditions, IP protection class,
measuring category, etc.).
• Do not use the probe after long periods of storage under unfavorable con-
ditions (e.g. humidity, dust or extreme temperature).
Electricity
• Installation, operation, and maintenance of this product must be performed
by qualified personnel only.
• Qualified personnel who work on or near exposed energized electrical con-
ductors must follow applicable safety related work practices and proce-
dures including appropriate personal protective equipment.
• Wear proper personal protective equipment, including safety glasses and
insulated gloves when making connections to power circuits.
• Hands, shoes, and floor must be dry when making any connection to a
power line.

• Never apply the probe around bare conductors with hazardous voltages
without having the appropriate permission to perform such work and with-
out wearing protective clothing and gloves as required.
• Connections must be made to the measuring device first, then to the circuit
to be monitored.
• The probe may only be used within the limits of the specifications listed in
this manual. Loads exceeding the specified values may destroy the probe
and the electrical equipment connected to it.
2 Applications
Please read this important information!
2.1 Intended Use / Use for Intended Purpose
The MAVOWATT 210 Rogowski current probes are based upon the Rogowski
principle. They can be used exclusively to measure AC current by being con-
nected to MAVOWATT 210 Three-phase Power and Energy Logger. The flexi-
ble probes allow current measurements on conductors that are hard to reach.
Installation, operation, and maintenance of this product must be performed by
qualified personnel only. Safety of the operator, as well as that of the product,
is only assured when it’s used for its intended purpose.
2.2 Use for Other than Intended Purpose
Using the product for any purposes other than those described in the con-
densed operating instructions or these product operating instructions is con-
trary to use for intended purpose.
2.3 Liability and Guarantee
Gossen Metrawatt GmbH assumes no liability for property damage, personal
injury or consequential damage resulting from improper or incorrect use of the
product, in particular due to failure to observe the product documentation.

4.1 Unpacking the Product
1. Carefully remove product and accessories from the packaging.
2. Check delivery for completeness and possible damage.
3. In case of detected damages, hidden defects and short deliveries, docu-
ment type and scope and contact the manufacturer or supplier immedi-
ately.
4. Keep packing material for further transport.
4.2 Making Measurement Connections
To perform measurements, the Rogowski current probes are first connected to
MAVOWATT 210. Subsequently, the Rogowski current probes are connected
to the object to be measured.
Attention!
!
To avoid the risk of electric shock or burns, always connect the earth
ground before making any other connections.
Attention!
!
Do not exceed the marked maximum ratings.
4.2.1 Connecting MAVOWATT 210 Rogowski Current Probes to MAVOWATT 210
MAVOWATT 210 is powered off.
1. Plug the output cable of the current probe to the current input of
MAVOWATT 210.
4.2.2 Connecting MAVOWATT 210 Rogowski Current Probes to the Circuit to be Measured
Attention!
!
DO NOT attempt to measure current in any circuit in which the circuit to
ground voltage exceeds the insulation rating of the current probe.
Attention!
!
Make sure the current probes are tightly closed. Keep mating surfaces
clean and free from foreign matter.

Note!
Do not locate the probe coupling close to other conductors carrying high
current.
Note!
Be sure to connect the current probes with the arrow pointing towards
the load or an erroneous power reading will result.
MAVOWATT 210 is powered off.
1. Open the probe coupling and slip the measuring head over the conductor
carrying the current to be measured.
2. Close the probe coupling such that it visibly and audibly snaps into place.
The arrow marking on the current probe points in the direction of current
flow and towards the load.
The conductor is centered within the measuring head.
The measuring head forms a perfect circle.

5Operation
For the different measurement configurations, refer to the Operating Instruc-
tions of MAVOWATT 210.
6 Maintenance
Cleaning
Keep the probe free of surface contamination. If necessary, clean the probe
with isopropyl alcohol.
