Update On Disk - TESTO 400 Instruction Manual

Notes: The given times refer to batteries/rechargeables with the capacities mentioned
opposite. This standard data is supplied by the manufacturers. The values are
subject to fabrication spreads - the storage times and storage temperatures also
play a role.
Rechargeable batteries have to be charged and discharged regularly in order to
retain their rated capacity. After not using the almost empty batteries they will
only have a fraction of their capacity available..
If the system has not been used for a longer period of time (e.g. more than 4 weeks)
remove all the batteries/rechargeable batteries from the instrument. Rechargeable
batteries should be stored in a charged condition separately.
testo 650 and testo 950 can be upgraded to have the full functions of testo 400. We will gradually
introduce branch-specific and user-specific software updates for the instruments.
Please ask your Testo service department or Testo dealer.
A simple instrument update e. g. firmware V1.20 to V1.21 can be performed by you.
