Initial start-up
The charging time is 10 hours with a simultaneous ul-
trasonic inspection. If the instrument is not being used
for ultrasonic inspections, the charging time is 8 hours.
This charging time applies to ambient temperatures
from 25 to 30 °C. Please take into consideration that
the batteries are not charged to their full capacity at
higher temperatures.
The LED display on the plug-in power supply unit indi-
cates the status of the charging process.
