Safety Instructions
Your
HAMEG
HO79-6
Interface has been assembled and tested according to the
German standard VDE 0411, part 1 (Safety requirements for electrical equipment for
measurement, control and laboratory use). This standard corresponds to the internatio-
nal IEC 1010-1 and European EN 61010 regulations. It has left the factory in optimal
condition regarding safe operation. To maintain this condition and to ensure danger-free
operation, the user of the
HO79-6
must adhere to the indications and warnings made
in this manual.
The interface
HO79-6
may only be operated with
HAMEG
oscilloscopes which correspond
strictly to Safety Class I conditions.
Interface casing, chassis, and all connectors at the
HO79-6
have a galvanic connection
to the protective earth line via the oscilloscope.
WARNING
A protective earth connection by way of the grounding conductor in the power
cord is essential for safe operation. It is not permitted to disconnect the
protective earthing. Measurements with the scope’s reference connector on
a voltage potential deviating from 0 Volt will immediately destroy the
oscilloscope, the interface and attached devices. This is valid even for extra
low potential (up to 42 V). Higher voltages will cause danger to life!
Please observe the safety regulations in your country!
If at any time there is suspicion that the unit can no longer be operated safely, it
should be withdrawn from operation immediately and measures taken to prevent
accidental use.
Such suspicion is justified if
- the unit shows visible damage,
- the unit contains loose parts,
- the unit has been stored in questionable conditions for an appreciable period of
time (e.g. outdoors or in a moist room).
Before opening the unit and while it is open, it should be separated from its power
source (the oscilloscope).
Environmental conditions
The permissable ambient temperature range for operation is 10°C to 40°C (50°F to 108°F).
During storage and transport, the temperature may be in the range of -40°C to +70°C
(-40°F to 158°F). During condensation buildup and in explosive atmospheres, the unit must
no be activated. It is very important to keep the ventilation holes free from obstruction.
Warranty
HAMEG
warrants to its Customers that the products that it manufactures and sells will
be free from defects in materials and workmanship for a period of 2 years. This warranty
shall not apply to any defect, failure or damage caused by improper use or inadequate
maintenance and care.
HAMEG

warranty to repair damage resulting from attempts by personnel other than
