AMA 310/UMS V21.0
Chapter 1 Notes on Safety, Usage, Maintenance and Service
1.1 Safety Instructions
This instrument has been built and tested in accordance with EN 61010-1, protective measures for
electronic measuring equipment. The instrument has been supplied ex works in a perfectly safe
condition. To maintain this condition and to ensure a safe operation, the user has to observe the
instructions and warnings included in these operations instructions.
The instrument corresponds to protection class II (protective insulation).
The instrument corresponds to protection class IP20 according to EN 60529.
The instrument must only be operated with supply voltages between 100-240 V with 50-60 Hz.
Discharges through a plug and socket connection may damage the instrument. During handling
and operation, the instrument has to be protected against electrostatic discharge.
No external voltages higher than 70 Veff must be applied to the RF input of the measuring receiver,
as otherwise the input circuits may be destroyed.
The ventilation slots of the instrument must not be covered. If covered, this may result in a reduced
air circulation in the instrument, leading to a heat accumulation and thus to an overheating and
damaging of the electronic components.
1.2 Usage Notes
The warranty for a new instrument ends 24 months after leaving the factory.
If the instrument is opened, the warranty claim becomes void!
Pointed tools (e.g. screwdrivers) may damage the plastic pane of the TFT display and thus result in
a destruction of the TFT.
If the ambient temperature falls below 5 °C, the contrast of the TFT display is impaired.
After a cold start of the instrument, the TFT display reaches its maximum brightness only after
some seconds.
The instrument reaches the full measuring accuracy only after an operating time of about 5
minutes.
Cordless DECT telephones as well as GSM or LTE mobile phones may lead to functional disorders
and faulty measurements when operated in the immediate vicinity of the measuring receiver.
1.3 Maintenance of the Instrument
The instrument is maintenance-free.

Chapter 1 - Notes on Safety, Usage, Maintenance and Service 5
AMA 310/UMS V21.0
1.4 Cleaning of the Instrument
The casing and the TFT display should be cleaned with a soft, lint-free cloth. Never use solvents
such as cellulose thinners, acetone and the like, as otherwise the front foil coating may be
damaged.
The ventilation slots should be cleaned from dust at regular intervals, such that the air circulation
through the instrument by the built-in ventilators will not be impaired.
1.5 Calibration
The measuring instrument should be calibrated at least every two years. During servicing the
instrument will be automatically calibrated in the factory.
1.6 Service
The service address is given on the back cover of this instruction manual.
