Inrush Current - Klein Tools CL440 Manual De Instrucciones

Apply test leads to the circuit to be tested to measure voltage.
The meter will auto-range to display the measurement in the most
appropriate range.
NOTE: If "–" appears on the LCD, the test leads are being applied to
the circuit in reverse. Swap the position of the leads to correct this.
NOTE: To access mV range for V AC , the 'RANGE' button
be used.
Manual Mode Sequence
AC Range 0-750V
DC Range 0-60.00V 0-6.000V 0-600.0mV 0-600.0V 0-60.00V
NOTE: When in a voltage setting and the test leads are open,
readings of order mV may appear on the display. This is noise and
is normal. By touching the test leads together to close the circuit
the meter will measure zero volts.
