However, electrical noise or intense electromagnetic fields in the vicinity of
the equipment may disturb the measurement circuit. Measurement
instruments will also respond to unwanted signals that may be present.
Users should exercise care and take appropriate precautions to avoid
misleading results in the presence of electromagnetic interference.
3. OPERATION
3.1. Precautions
Warning: Before using the instrument, read the Safety Information
Section, and examine it for damage or contamination (excessive dirt,
grease, etc.). Check the test leads for any evidence of cracked or
frayed insulation. If any abnormal conditions exist, do not use the
meter.
Warning: When using probes, keep your fingers behind the guards.
Warning: Measuring voltages which exceed the limits of the meter
may damage it and expose the operator to a shock hazard. Always
work within the meter voltage limits indicated on it's front panel.
Warning: Never ground yourself when taking electrical
measurements. Do not touch exposed metal pipes, outlets, fixtures
etc. which may be at ground potential. Keep your body insulated by
wearing dry clothing, rubber shoes or stand on a rubber mat, or other
suitable material.
3.2 Range selection
When the function (for example, AC Volts) has been selected and a signal
is present, the MM35 will autorange until the most suitable range has been
selected. The reading will be displayed and the meter will continue to
change range according to variations in the input.
