In schools, training centres, computer and self-help workshops, handling of measuring instruments must be super-
vised by trained personnel in a responsible manner.
Before measuring voltages, always make sure that the measuring instrument is not set to a measuring range for cur-
rents.
The voltage between the connection points of the measuring device and the ground potential must not exceed 600 V
DC/AC in overvoltage category III or 1000 V DC/AC in overvoltage category II.
The test prods have to be removed from the measured object every time the measuring range is changed.
Be especially careful when dealing with voltages higher than 25V AC or 35 V DC. Even at such voltages you can
receive a life-threatening electric shock when you come into contact with electric wires.
Check the measuring device and its measuring lines for damage before each measurement. Never carry out any
measurements if the protecting insulation is defective (torn, ripped off etc.)
To avoid an electric shock, make sure not to touch the connections/measuring points to be measured neither directly
nor indirectly during measurement. During measuring, do not grip beyond the tangible grip range markings present on
the test prods.
Do not use the multimeter just before, during or just after an electrical storm (electrical shock / high-energy overvolt-
ages!). Please make sure that your hands, your shoes, your clothing, the floor, switches and switching components
are dry.
Avoid an operation near:
- strong magnetic or electromagnetic fields
- transmitting aerials or HF generators.
since this could affect the measurement.
If you have a reason to believe that the device can no longer be operated safely, disconnect it immediately and secure
it against being operated unintentionally. It can be assumed that safe operation is no longer possible if:
- the device exhibits visible damage,
- the device does not operate any longer and
- the device was stored under unfavourable conditions for a long period of time or
- the device was exposed to extraordinary stress in transit.
Do not switch the measuring instrument on immediately after it has been taken from a cold to a warm environment.
Condensation water that forms might destroy your device. Leave the device switched off and wait until it has reached
room temperature.
Do not leave the packaging material lying around carelessly since such materials can become dangerous toys in the
hands of children.
You should also heed the safety instructions in each chapter of these instructions.
Product Description
The multimeter (referred to as DMM in the following) indicates measured values on the digital display. The measuring
value display of the DMM comprises 4000 counts (count = smallest display value).
The measuring device can be used for do-it-yourself or for professional applications.
For better readability, the DMM can also be mounted with the clip on the rear.
The mA current section shows an absolute novelty. With this measuring device, it is no longer necessary to replace an
accidentally triggered mA fuse. The installed PTC fuse resets automatically after tripping.
