Voltcraft DLA-1L 16 ユーザーズマニュアル

The measuring 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 

single-phase devices with protective contact or euro plugs. The measuring adapter is 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. 250 V/AC which are fused with 16 A.
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, fire, electric 

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

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, flammable 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 specified 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, modifications and repairs are to be performed exclusively by an 

expert or at a qualified 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 qualified specialist.

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. Depending on the position of the plug, the current can be 

measured from measuring chamber L or N and, not depending on the position, also 

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. Both main conductors phase L and protective conductor PE are freely 

accessible via the insulated measuring chamber without opening the mains cable at great 

expense. The current via L respectively N can be measured at the measuring chamber 

L depending on the plug position. The measuring chambers are correspondingly labeled 

(L, PE).

The measuring sockets are 

for voltage measurement.

Current clamp is 

not included in the 

delivery content.

Proceed as follows to conduct a measurement:
•  Plug the measuring adapter between the electrical consumer and power socket. Ensure the 

firm fit of the power plugs.

•  Observe the instruction manual of your current clamp or multimeter. 
•  Place the current clamp around the measuring chamber L or PE 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:
