Annex B:Maintenance and Care of Oscilloscope
General maintenance
Do not put or leave the instrument in a place where the LCD display will be exposed to direct sunlight for
long period.
Caution: To avoid damage to the oscilloscope or probes, do not expose them to sprays, liquids, or solvents.
Clean oscilloscope
Examine the oscilloscope and probes as often as operating conditions require. To clean the exterior surface,
perform the following steps:
⚫ Use a soft cloth to remove floating dust on the outside of the oscilloscope and probes. Take care to avoid
scratching the touch screen while cleaning.
⚫ Use a soft cloth dampened with water to clean the oscilloscope while doing this please keep the power off.
Wipe with a mild detergent and water. Do not use any corrosive chemical cleaning agent, in order to avoid
damaging the oscilloscope or probe.
⚫ Clean the ventilation hole with a soft brush to keep it unimpeded. Do not use any corrosive chemical cleaning
agent, so as to avoid damage to the oscilloscope motherboard.
⚫ If the fan needs to be cleaned, please consult the after-sales service personnel, so as to avoid damage to the
oscilloscope.
Warning
Make sure the instrument is dry before recharging, to avoid electrical short circuit or personal injury caused by
moisture.
Store oscilloscope
The lithium battery needs to be charged before storing the oscilloscope for a long period.
Battery charge
Upon delivery, the lithium battery may not be charged. It takes 6 hours to be fully charged (the oscilloscope is
recommended to turn off to save the charging time). When running on battery power, the battery level indicator
in the lower right corner of the screen will indicate the battery usage.
Caution: In order to avoid charging battery from overheating, do not use beyond the permitted
environmental temperature value given in the technical specification.
