  Safety 

Spectrum Analyzer 

This instrument is Safety Class III according to IEC classification and has been designed to meet the 
requirements of EN61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control 
and Laboratory Use). 

This instrument has been tested in accordance with EN61010-1 and has been supplied in a safe 
condition. This instruction manual contains some information and warnings which have to be followed by 
the user to ensure safe operation and to retain the instrument in a safe condition. 

This instrument has been designed for indoor use in a Pollution Degree 2 environment in the 
temperature range 5°C to 40°C, 20% - 80% RH (non-condensing). It may occasionally be subjected to 
temperatures b5° and  -10°C without degradation of its safety.  Do not operate while 
condensation is present. 

Use of this instrument in a manner not specified by these instructions may impair the safety protection 
provided.  

WARNING! 

All accessible parts will be at the same voltage as the outer body of the SMA input socket.  In particular, 
note that the shell of the mini-USB connector is galvanically connected to the body of the SMA input 
which will therefore be at earth ground potential when the USB port is connected to a desktop PC.  To 
maintain user safety under all other circumstances it is essential that the input is not connected to a 
voltage above 30Vdc or 30Vrms with respect to earth ground which is the limit of Safe Extra Low Voltage 
(SELV) by IEC definition. 

The instrument shall be disconnected from all voltage sources before it is opened for any adjustment, 
replacement, maintenance or repair. 

Any adjustment, maintenance and repair of the opened instrument under voltage shall be avoided as far 
as possible and, if inevitable, shall be carried out only by a skilled person who is aware of the hazard 
involved.   

Do not wet the instrument when cleaning it. 

The following symbols are used on the instrument and in this manual. 

 

Direct Current 

 

CAUTION – refer to accompanying documentation. 
Damage to the instrument may occur if these precautions are ignored. 

 

Adaptor/Charger 

The adaptor/charger supplied has a universal input voltage rating of 100-240VAC, 50/60Hz. It is a  
Class II (double insulated) device, fully approved to EN 60950-1 (2001), UL 60950 (UL listing E138754) 
and AS/NZS CISPR:2002 (C-Tick).
