OPERATING INSTRUCTIONS
MEASURING ADAPTER for 3P + N + E
Model No.: MS-838A-16 (16A)
Model No.: MS-838A-32 (32A)
INTENDED USE
The adapter measures together with a clamp meter or multimeter (clamp meter and
multimeter are not included in the delivery content) the electrical current and voltage of
three-phase devices with CEE plug. The measuring adapter is easily inserted between the
electrical consumer and the socket. The measuring adapter may only be used in the range of
the overvoltage category CAT II in AC voltage networks with a nominal voltage of max. 415 V/
AC which are fused with 16 A (Model No.: MS-838A-16) and with 32 A (Model No.:
MS-838A-32).
The current is measured with commercial AC current clamps on the insulated measuring
chambers and the voltage is measured with voltage measuring devices on the measuring
sockets. It is possible to measure the current from phase L1,L2, L3 or on the measuring
chamber Nand also the leakage current (stray current) at the measuring chamber PE.
Only use the measuring adapter for the duration of the measurement. A permanent retention
in the mains cable circuit is not permitted.
The measuring operation is only permitted in dry surroundings.
For safety and approval purposes (CE/UKCA), you must not rebuild and/or modify this product.
If you use the product for purposes other than those described above, the product may be
shock etc. Read the instructions carefully and keep them. Make this product available to third
parties only together with its operating instructions.
This product complies with the statutory national and European requirements. All company

OPERATION
The current is measured with commercial AC current clamps on the insulated
measuring chambers and the voltage is measured with voltage measuring devices
on the measuring sockets. The current can be measured from measuring chamber
L1,L2, L3 or Nand the leakage current (stray current) can be measured at the
measuring chamber PE. Both types of measurement can be carried out at the same
time.
Only use the measuring adapter for the duration of the measurement. A permanent
retention in the mains cable circuit is not permitted.
CAT II Overvoltage category II for measurements on electric and electronic devices
connected to the mains supply with a mains plug. This category also covers all
lower categories (e.g. CAT I for measuring signal and control voltages).
The measuring adapter allows for easy current measurement in closed line systems with
measuring chamber without opening the mains cable at great expense. The measuring
chambers are correspondingly labeled (L1,L2, L3, N, PE).
Current clamp is
not included in the
delivery content.
The measuring sockets DMM is not

the delivery
content
are for voltage
measurement.
Proceed as follows to conduct a measurement:
•Plug the measuring adapter between the electrical consumer and power socket. Ensure the
•Observe the instruction manual of your current clamp or multimeter.
•Place the current clamp around the measuring chamber for the current to be determined.
The current clamp must be completely closed to avoid measuring errors.

•If you use a multimeter for voltage measurement proceed in the following order:
- Connect the safety measuring cables to the digital-multimeter according to the instruction
manual.
- Use only suitable safety measuring cables.
- Open the cover of the measuring adapter and plug the measuring cables into the sockets
on which you want to measure a voltage.
•Remove the current clamp from the measuring chamber and the plugs of the safety
measuring cables from the measuring sockets after carrying out all measurements. Close
the cover for the measuring sockets.
•Remove the measuring adapter from the power line.
The following measuring values can be determined:
Measuring chamber Reading
L1 Current via phase L1
L2 Current via phase L2
L3 Current via phase L3
N Current via neutral conductor N
PE Leakage current (stray current) via earth conductor
MAINTENANCE AND CLEANING
•Disconnect the power plug from the socket and disconnect all connected devices before
each cleaning.
•Apart from the occasional cleaning the adapter is maintenance free.
•The outside of the housing should only be cleaned with a soft, dry cloth or brush. Never use
any aggressive cleaning agents or chemical solutions as they may cause damage to the
housing or cause the product to malfunction.
DISPOSAL
Electronic devices are recyclable waste and must not be disposed of in the
