REL/AC+DC button
The RELATIVE function zeros out the reading on the display and stores it as
a reference. Subsequent readings will be displayed as the relative difference
between the actual measurement and the stored reference value.
To activate, momentarily press the REL/AC+DC button. The “REL” indicator
will appear on the LCD display along with the relative reading. Momentarily
press the REL/HZ button again to return to normal operation.
NOTE
The meter does not Autorange when the Relative mode is active.
The display will read OL if the difference exceeds the range. When
this occurs, exit REL and use the RANGE button to select a higher
range. REL does not work on Frequency, Duty Cycle, or
Temperature.
The AC+DC function measures both the AC and DC components to derive
the effective RMS (AC+DC) value. The AC+DC mode is typically used when
measuring voltage on unfiltered rectifier circuits. To activate, press and hold
the REL/AC+DC button until ‘AC+DC’ appears on the LCD display.
NOTE
AC+DC can only be accessed when the meter is set to AC or DC
voltage.
