Disposal
a) Product
Electronic devices are recyclable waste and must not be disposed of in the
household waste. At the end of its service life, dispose of the product according to
the relevant statutory regulations.
Remove any inserted (rechargeable) batteries and dispose of them separately from
the product.
b) (Rechargeable) batteries
As the end user, you are required by law (Battery Ordinance) to return all used
(rechargeable) batteries; disposal of them in the household waste is prohibited!
Contaminated (rechargeable) batteries are labelled with this symbol to indicate that
disposal in the domestic waste is forbidden. The designations for the heavy metals
involved are: Cd = Cadmium, Hg = Mercury, Pb = Lead (name on (rechargeable)
batteries, e.g. below the trash icon on the left).
Used (rechargeable) batteries can be returned to collection points in your municipality, our
stores or wherever (rechargeable) batteries are sold.
You thus fulfil your statutory obligations and contribute to the protection of the environment.

expert.
Do not exceed the maximum permitted input values. Do not touch any circuits or
parts of circuits, if they can have higher voltages than 25 V Acrms or 35 V/DC. Mortal
danger!
Regularly check the technical safety of the device and the measuring cables, e.g. for
damage to the casing etc. Do not use the measuring device in case of damage!
The measuring range diodes and the battery test, rectangular signal generator as well as
resistance measuring are not protected against excess input voltage or overload. Exceeding
the max. admissible input values or overload may damage the measuring device or lead to
mortal danger!

Never measure currents above 200 mA in the μA/mA range, since this would cause
the fuse to trip. The voltage in the measuring circuit may not exceed 250 V. In current
measuring range the two test prods have a low-impedance connection. Merely
touching a metal end poses the risk of an electric shock.
If measuring is no longer possible (measuring value does not change, etc.), the
internal fuse may have been triggered. See the next chapter to read about replacing
the fuse.
•
After you finish testing, always switch the measuring device off. Turn the rotary switch to
“OFF”.
Care and cleaning
Live components may be exposed if the covering is opened or components are
removed. The connected lines must be disconnected from all measuring objects
prior to cleaning or repairing the device.
• Disconnect the product from the power supply before cleaning.
• Do not use scrubbing agents or chemical agents containing petrol, alcohol or the like to clean
the product. These could corrode the surface of the measuring instrument. The fumes are
furthermore a health hazard and are explosive. Moreover, you should not use sharp-edged
tools, screwdrivers or metal brushes or similar for cleaning.
• To clean the device, the display or measurement lines, use a clean, dry lint-free anti-static
cleaning cloth.
• Do not immerse the product in water.
Replacing the fuse
If no measurement data is shown on the
display, the fuse is probably defective. The
fuse is integrated in the red test prod in a
user-friendly position. To replace the fuse,
proceed as follows:
• Turn off the measuring instrument and remove both test prods from the device under test.
• Unscrew the front end of the red test prod from the reaching area of the hands.
• Replace the defective fuse with a fuse of the same type and nominal current (quick-acting
0.5 A/250 V fine-wire fuse).
• Carefully screw the red test prod back together.
Inserting/changing the batteries
Operation of the measuring device requires two button cell batteries (LR44 or identical). A
battery replacement is required when the display becomes weaker.
To insert/replace the battery, proceed as follows:
• Disconnect the measuring device from the measuring circuit and turn it off.
• Loosen the casing screw on the rear and open the casing.
• Place new batteries into the battery compartment observing the correct polarity. Always
observe the indicated polarity.
• Now, close the cover carefully again.
Never operate the measurement device when it is open. RISK OF FATAL INJURY!
Do not leave flat batteries in the device. Even batteries protected against leaking
can corrode and thus release chemicals which may be detrimental to your health or
destroy the battery compartment.
Suitable replacement batteries are available under order number 652044 (order 1
set of 2).
Troubleshooting
In purchasing the DMM, you have acquired a product which has been designed to the state
of the art and is operationally reliable. Nevertheless, problems or faults may occur. For this
reason, the following is a description of how you can eliminate possible malfunctions yourself.
Error
Possible cause
The multimeter does not
function.
Are the batteries spent? Check the status.
No measuring value change. Is the wrong measuring function active?
The internal overload fuse is defective.
