Operation
RANGE Button
The Autorange mode automatically selects the proper range for the measurement
being made and is generally the best mode for most applications. For measurement
situations requiring that a range be manually selected, perform the following:
1. Momentarily press the RANGE button. The "AUTO" indicator will no longer be
shown on the LCD display.
2. Momentarily press the RANGE button to step through the available ranges until
the desired range is selected.
3. To exit the Manual Ranging mode, press and hold the RANGE button until the
"AUTO" indicator reappears.
NOTE: The range button does not work on Frequency, Duty Cycle, Capacitance
or Temperature.
MODE/Bluetooth ® Button
Momentarily press the MODE
button to select AC or DC, Frequency or Duty Cycle,
Resistance, Continuity or Diode Test and °C or °F.

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, Continuity, Diode Test or Temperature.

Operation cont.
REL/AC + DC button cont.
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. Press and hold the REL/AC + DC button to
exit AC + DC. The meter will return to AC voltage.
NOTE: AC + DC can only be accessed when the rotary function switch is set to voltage.
MAX/MIN/AVG Button
1. Momentarily press the MAX/MIN/AVG button to activate the MAX/MIN/Average
mode. "MAX" will appear on the LCD display and the meter will display and hold
the highest reading. The meter will update the reading when a higher "max" occurs.
2. Momentarily press the MAX/MIN/AVG button again to view the lowest reading. "MIN"
will appear on the LCD display and the meter will display and hold the lowest
reading. The meter will update the reading when a lower "min" occurs.
3. Momentarily press the MAX/MIN/AVG button once more to view the average reading.
"AVG" will appear on the LCD display and the meter will display the running average.
The meter will update the reading when the average value changes.
4. Press and hold the MAX/MIN/AVG button to end MAX/MIN/Average and return to
normal operation.
NOTE: The meter does not Autorange when the MAX/MIN/AVG mode is active. The
display will read OL if the range is exceeded. When this occurs, exit MAX/MIN/AVG
and use the RANGE button to select a higher range. MAX/MIN/AVG does not work
on Frequency, Duty Cycle or Capacitance.
HOLD/Blacklight Button
To freeze the reading on the LCD display, momentarily press the HOLD
The "HOLD" indicator will be displayed while the reading is being held. Momentarily
