Preparation And Caution Before Use - Innova 3320 Owner's Manual

PREPARATION AND CAUTION BEFORE USE.

Inspect the digital multimeter for damage to the case. Do
not use if cracked, distorted, excessively dirty or any
abnormal condition exists.
Inspect the test leads for damage. Check for cracked
insulation, broken or damaged probes, loose or bent probe
pins. Do not use if any abnormal condition exists.
Set the Function/Range Selector Switch to the proper
range BEFORE taking measurements. If the range/function
must be switched during a test, ALWAYS remove the test
leads from the circuit being measured before switching
settings.
To avoid possible electric shock, instrument damage,
and/or equipment damage when taking voltage or current
measurements, DO NOT exceed the maximum value of the
selected range.
If the unit is used near high noise Radio Frequency (RF)
generating equipment (spark plug wires, ignition coils or
alternator), the display may become unstable or indicate
large errors. If you obtain erratic readings during use,
isolate the Multimeter as far away as possible from these
components.
