3.3.2 Power-up Sequence
On power-up, AT680 performs self-tests on its FlashRom, RAM and momentarily lights
all segments and annunciators. If a failure is detected, the instrument will not enter the
measurement state.
3.3.3 Power-up Defaults
The power-on default will be the last configuration you saved.
3.3.4 Warm-up Time
AT680 is ready to be used as soon as the power-up sequence has completed. However, to
achieve the accuracy rating, warm up the instrument for 30 minutes.
