Zero button 9 for two seconds to turn on/off the APO function. NOTE: APO on is
the default setting.
P1/P2 BUTTON 3
Repeated presses will toggle between P1, P2, and differential (P1-P2)
measurements. NOTE: P1 is the meter default.
UNITS BUTTON 4
Repeated presses will toggle between bar, oz/in 2 , psi, mbar, kPa, inHg,
mmHg,kg/cm 2, inH2O, ftH20, and cmH2O options.
HOLD BUTTON 6
Press to lock the current reading on the display. Reading will remain on the
display until pressed again, or until the meter automatically powers off.
MAX/MIN BUTTON 7
Press to toggle between the Maximum, Minimum, and Average values. Press and
hold for two seconds to exit the selected mode.
BACKLIGHT BUTTON 8

Press the Zero button 9 before taking pressure readings, it will zero both P1 and P2 ports.
-
Connect a single hose to measure pressure relative to ambient pressure or attach both hoses for differential pressure (P1-P2).
-
Press the P1/P2 button 3 to toggle between the P1, P2, or Differential Pressure measurements on the display.
-
Press the Unit button 4 to change to the desired unit.
NOTE: “OL” is displayed on the LCD if the pressure is outside the
measurement range.
NOTE : “ERR” is displayed on the LCD if the sensor has been damaged. The
