Maintenance Features
Cleaning:
Clean only the exterior with a damp, soft cloth. Do not use chemicals or abrasives. Unplug the power cord before cleaning.
Equipment Maintenance and Service:
Do not dismantle the instrument for maintenance due to high voltage components and static-sensitive internal devices. Return to the factory or designated maintenance organization for service. Ensure power is disconnected before any repair.
Self-Calibration:
Recommended if ambient temperature changes by more than 5 ℃. Disconnect all inputs and allow the oscilloscope to warm up for at least 30 minutes before performing self-calibration.
Firmware Upgrade:
Firmware can be upgraded via external USB memory devices. Ensure the U disk contains the correct upgrade file (*.ads). Do not cut off power during the upgrade.
Self-Test:
Includes screen, keyboard, and LED tests to check for electrical or mechanical problems with the user interface.
Abnormal Conditions:
Do not operate if there are visible signs of damage or if the scope has been subjected to severe transport stresses. Disconnect power if protection is suspected to be impaired.
Safety Compliance:
Complies with UL 61010-1:2012/R: 2018-11 and CAN/CSA-C22.2 No. 61010-1:2012/A1:2018-11 for safety requirements of electrical equipment for measurement, control, and laboratory use.
