    Safety Precautions
 
3
  If you use an electrical outlet that does not have a protective grounding conductor, 
ensure that an equivalent protective conductor is installed by a certified electrician 
(as specified in the applicable regulations for installation in your country).  
The protective effect must not be negated by using an extension cord without  
a protective grounding conductor. 
Before using for the first time, any superstructure parts must be completely installed. 
Avoid connecting the equipment to lines that have a heavy electrical load, e. g. 
compressors, large machinery, etc.
    Warm-up Time
    To deliver exact results, the device must warm up for at least 30 minutes after  
connection to AC power. Only after this time will the device have reached the 
required operating temperature.
 
Using a Verified Device in Legal Metrology:
    Ensure that there is a warm-up time of at least 24 hours after connection to the 
power supply.
