Service and calibration
To maintain the long-term accuracy of the Multimeter, it must be calibrated every
year. Changing fuses is described in the Notes on Safety (page 6). For cleaning the
device or the display window, use only a clean, dry, antistatic lint-free cleaning rag.
Important!
Never use cleaning agents containing carbon, petrol, alcohol or
similar since these will attack the surface finish of the measuring
device. Also, the vapors are a health and explosion hazard. Never
use sharp tools, screwdrivers or metal brushes, etc. when
cleaning.

Disposing of the device
Dispose of the Bench Multimeter according to current legal regulations!
What to do in case of malfunction
With the Bench Multimeter MXD-4660A, you have acquired a state-of-the-art mea-
suring device. Even so, faults may occur. This is how you can deal relatively easily
with some of these faults:
Problem
Possible solution
No display
Is the device switched on?
Is the mains plug making correct contact, both at the
device and at the socket?
Is the mains fuse OK?
No current
Are the fuses for the various current measuring ranges
measurement possible
faulty?
No transfer to PC
Is the interface cable making correct contact, both at
the PC and at the measuring device?
Are the measuring device and PC on and the software
loaded/started up?
Important!
Please read and observe the Notes on Safety!
When opening panels or removing parts (except if this is manually
possible), live components may be exposed. Connecting points
may also be live. Ahead of any adjustment, maintenance, repair or
exchange of parts or sub-assemblies during which the unit must
be opened, they must be disconnected from all voltage sources
and measurement circuits. If adjustment, maintenance or repair
must then proceed with the unit open, only trained engineers,
familiar with the risks and relevant regulations (VDE 0100, VDE-
0701, VDE-0683), are authorized to complete the work. Capacitors
in the device may still be charged, even if the device has been dis-
connected from all voltage sources and measuring circuits.
