DLA-3L MEASURING ADAPTER
ITEM NO.: 1271061 - DLA-3L 16
ITEM NO.: 1271062 - DLA-3L 32
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 III in AC voltage networks with a nominal voltage of max.
415 V/AC which are fused with 16 A (ITEM NO.: 1271061 - DLA-3L 16) and with 32 A (ITEM
NO.: 1271062 - DLA-3L 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 N and 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), 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
damaged. In addition, improper use can cause hazards such as short circuiting, re, electric
shock etc. Read the instructions carefully and keep them. Make this product available to third
parties only together with its operating instructions.

SAFETY INSTRUCTIONS
Read the operating instructions carefully and especially observe the safety
information. If you do not follow the safety instructions and information
on proper handling in this manual, we assume no liability for any resulting
personal injury or damage to property. Such cases will invalidate the
warranty/guarantee.
a) Persons / Product
• The device is not a toy. Keep it out of the reach of children and pets.
• Do not leave packaging material lying around carelessly. These may become
dangerous playing material for children.
• Protect the product from extreme temperatures, direct sunlight, strong jolts, high
humidity, moisture, ammable gases, vapours and solvents.
• Do not place the product under any mechanical stress.
• If it is no longer possible to operate the product safely, take it out of operation and
protect it from any accidental use. Safe operation can no longer be guaranteed if
the product:
- is visibly damaged,
- is no longer working properly,
- has been stored for extended periods in poor ambient conditions or
- has been subjected to any serious transport-related stresses.
• Please handle the product carefully. Jolts, impacts or a fall even from a low height
can damage the product.
• Also observe the safety and operating instructions of any other devices which are
connected to the product.
• The measuring adapter and the plugs may not be disassembled.
• The voltage and current range specied should not be exceeded.
• The measuring adapter may only be used for current and voltage measurement.
• The user is not allowed to put other items than suitable safety measuring cables
in the sockets
• Current measurement on the measurement sockets is not possible (an attempt
would short-circuit the device)!
• The user may not short-circuit the contacts of the measuring adapter.
b) Miscellaneous
• Consult an expert when in doubt about operation, safety or connection of the
device.
• Maintenance, modications and repairs are to be performed exclusively by an
expert or at a qualied shop.
If you are not sure about the correct connection or use, or if questions arise which are not
covered by these operating instructions, please do not hesitate to contact our technical
support or another qualied specialist.

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 N and 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 III Overvoltage category III for measuring in building installation (e.g. outlets or
sub-distribution). This category also covers all smaller categories (e.g. CAT II for
measuring electronic devices).
The measuring adapter allows for easy current measurement in closed line systems with
power plugs. The ve individual inner conductors are freely accessible via the insulated
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 are
for voltage measurement.
Proceed as follows to conduct a measurement:
• Plug the measuring adapter between the electrical consumer and power socket. Ensure the
rm t of the power plugs.
• 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.
