MAINTENANCE
4.1 Warning
• Removethetestleadsfromanyinputbeforeopeningthecase.Donot
operate the instrument without a battery case cover.
• To avoid electrical shock, do not attempt to perform any servicing
unlessyouarequaliedtodoso.
• If the meter is not going to be used for a long period of time, take
out the batteries. Do not store the meter in high temperatures or high
humidity.
• Toavoidelectricalshockand/ordamagetotheinstrument,donotget
waterorotherforeignagentsintotheprobe.
4.2 Battery Replacement
• Thebatterieswillneedtobereplacedwhenthe symbol appears
on the display.
• The meter must be in the OFF position and disconnected from any
circuit or input.
• Usingascrewdriver,unscrewthefourscrewsofthebatterycompart-
