  Due to the high voltage inside the device during use, please do not disassemble it without permission. 

 

Cautious 

  Do not shake, drop or bump the calibrator while in use; 

  If condensation has occurred, thoroughly dry out the 762 before startup; 

  It is recommended to replace the medium (except for water medium) every 3 months. If the medium is contaminated, it 

needs to be replaced in time; 

  Do not apply more than 30V between any two electrical jacks (except for voltage measurement jacks); 

  Do not use any adapter other than Additel power adapter designed for the ADT762. Charge the battery as soon as the 

battery symbol indicates. 

  If the calibrator is not working properly, turn it off, remove the battery and contact Additel. 

  Do not remove the battery while it is charging or when the calibrator is in use. 

  Before turning off the calibrator, make sure the system pressure is reduced to the atmosphere pressure. 

  If the battery is not used for a long time, it should be charged to 50% to 80%, and it should be taken out of the device 

and stored in a dry and cool environment.  Charge the battery  every 3 months to prevent  it from being too low due to 

self-discharge and cause irreversible loss of capacity or even damage; 

  For water medium version, the medium should be drained before low temperature storage.
