4.3.2 Automatic internal calibration

The USS-DBS49 Analytical Balance offers four kinds of automatic internal

calibration time mode to choose from:

“

10mins Internal Cal

” “

30mins

Internal Cal

” “

60mins Internal Cal

”

and

“

Internal Cal Off

”

. Respectively,

these modes indicates that that the balance is automatically calibrated

either every 10 minutes, every 30 minutes, every 60 minutes or the

automatic calibration is off.
