SAFETY PRECAUTIONS

The following general safety precautions must be observed during all phases of operation, service, 
and repair of this instrument. Failure to comply with these precautions or with specifi c WARNINGS 
elsewhere in this manual may impair the protection provided by the equipment. Such noncompliance 
would also violate safety standards of design, manufacture, and intended use of the instrument. 

IET Labs assumes no liability for the customer’s failure to comply with these precautions.

The SRL is an indoor use product.

DANGEROUS PROCEDURE WARNINGS

Comply with all WARNINGS - Procedures throughout in this manual and instructions on the 
instrument prevent you from potential hazard. These instructions contained in the warnings must 
be followed.

BEFORE APPLYING POWER
Verify that all safety precautions are taken. Make all connections to the instrument before applying 
power. Note the instrument’s external markings described under “Safety Symbols”.

     • DO NOT Operate in an Explosive Atmosphere

     • Do not operate the instrument in the presence of infl ammable gasses or fumes 
     • Operation of any electrical instrument in such an environment clearly constitutes a safety  
hazard
     • Use Caution around live circuits and whenever hazardous voltages > 45 V are present
     • Operators must not remove instrument covers 
     • Component replacement and internal adjustments must be made by qualifi ed maintenance 
personnel only 
     • DO NOT substitute parts or modify the instrument
      • When working with high voltages; post warning signs, train personnel and keep unauthorized 
personnel away.

To  avoid  the  danger  of  introducing  additional  hazards,  do  not  install  substitute  parts  or  perform 
unauthorized modifi cations to the instrument.  

Return the instrument to an IET Labs for service and repair to ensure that safety features are maintained 
in operational condition.
