Routine Inspection
Look for any cracks or other damage to the enclosure, missing ports, etc.
Cleaning
Disconnect the instrument from the Mains Power. Wipe it with a clean cloth slightly damped with water or
Isopropyl alcohol (IPA). Care should be taken near the terminals, the IEC Mains Power and USB sockets.
Allow the instrument to completely dry before it is used.
Instrument Care
The instrument should always be handled with care and not dropped. Always make sure that the instrument is
secured when being transported to prevent mechanical shock.
Test Leads
Leads are silicone insulated and work well in all weather conditions. Always keep the leads in a suitable lead bag
when in storage or transportation.
Regular inspection of leads is recommended to make sure that they are not damaged in any way. Damaged leads
could affect resistance readings and are a safety hazard.
