5.2 Inspection
The user is protected from electrical shock by the insulation of the 260 and its test

chips, burns or deterioration that ex-
pose internal metal parts or reduce
the spacing between such metal
parts and hand contact by the opera-
tor.
Make certain that the battery com-
partment cover is securely fastened
in place before the Instrument is
used.
Do not use an Instrument with a bro-
ken meter glass.
