Operating conditions 

Use this unit within the scope of the environment set forth in the 

specification. 

 

Maintenance 

The electric circuit in this instrument uses aluminum electrolytic 

capacitors. Generally speaking, the life of the aluminum electrolytic 
capacitor  becomes short as the ambient temperature rises. To prevent 
components from damage, it is recommended to conduct maintenance at 
ULVAC about once every 3 years. 

 

Cautions in shipping the unit 

If the unit is to be shipped back to ULVAC, pack it in the original 

condition. If it is shipped bare, it may be damaged.
