MIN AVG" appear on the display. The meter beeps when new maximum or minimum
reading is updated. The average reading is calculated over time. Press the button
momentarily to read the MAX, MIN and AVG readings in sequence. Press the button
for 1 second to exit MAX/MIN/AVG recording mode. APO is disabled automatically in
this mode.
• SELECT: Press momentarily to toggle between functions, measurement modes,
or display modes. The last used setting becomes the default when that function is

this mode.
• Intelligent Auto Power Off (APO): The meter automatically turns off after approxi-
mately 32 minutes of inactivity to extend battery life. Active meter function is specified
as: selector switch is rotated or pushbuttons are pressed; readings above 8.5% of
the range; non-OL readings for resistance, continuity, or diode function; non-zero
readings for Hz function; phase rotation segment moving. To wake up the meter from
Auto Power Off, press the SELECT button momentarily and release or turn the rotary
switch OFF and then back on. Always turn the rotary switch to the OFF position when

• ∆: Press the ∆ button for 1 second to toggle between zero and normal mode. In zero
mode the value on the LCD when the button is pressed becomes the offset. As the
input value changes, the offset is subtracted from the actual value. This modified
value is shown on the LCD.
Note: ∆ operation when DCA or DC + ACA functions are selected offsets any mag-
netic hysteresis in the jaw. If DCA or DC + ACA reading before measuring is not zero,
press the ∆ button for 1 second. The LCD will display "dc_0". When this clears, the
meter is ready for operation. When measuring more than 5 A, this mode is disabled.
As an indication, the meter will beep three times.
