Ambient Temperature and Humidity
Ambient temperature:  5 to 35°C
Ambient humidity:    80% RH or lower (no condensation present)
Note
Condensation may occur if the instrument is moved to another place where the ambient 
temperature is higher, or if the temperature changes rapidly. In such cases, allow sufficient time 
for the instrument to adjust to the ambient temperature before use. 
When the instrument is packaged in a box and moved, prevent condensation by allowing 
sufficient time for the instrument to acclimatize before removing it from the box. 
Do Not Install the Instrument in the Following Places
• Outdoors.
•  Dangerous locations where flammable or explosive gasses, vapors, or dust is present, 
or where the possibility of explosions or fires exists. 
•  In direct sunlight or near heat sources.
•  Where an excessive amount of soot, steam, dust, or corrosive gas is present.
•  Location where mechanical vibration is high.
•  In an unstable place.
•  Where the instrument is exposed to water or other liquids.
General Handling Precautions
•  Do Not Place Anything on Top of the Instrument 
  Never stack instruments or place any other objects on top of the instrument, especially 
those containing water. Doing so can lead to malfunction.
•  Take Proper Care When Carrying the Instrument
  The instrument should always be carried by two people. Hold the instrument by the 
handles on the sides of the case. The instrument weighs approximately 19 kg. Take 
precautions against injuries when carrying it. 
Also, always turn the power switch OFF, 
remove the power cable, and confirm that no other cables are connected before 
carrying the instrument. 
•  Clean the Instrument Properly
  When removing dirt from the case or operation panel, disconnect the power to the 
circuits under test and the instrument, remove the instrument’s power cord from the 
power outlet, then wipe gently with a clean, dry cloth. Do not use volatile chemicals 
since this might cause discoloring and deformation.
