KEY OPERATION

1. Power on/off Button

   • When the power r is off, short press the button to turn the meter on.
   • When the powe is on,
   • Short press the button to disable and enable the automatic power off function.
   • Press and hold the button to turn off the meter.

The auto power off disable indicator will appear on the display when the auto power off function is disabled. The meter will now remain on until the user turns it off or until the battery runs out.
     Note that the Auto Power OFF function will be reactivated the next time the meter is turned off and then on.

2. BACKLIGHT BUTTON

   •  Short press the button to store the current measured pressure value with a time stamp (can store up to 99 groups).
   • Press and hold the button to open/close the backlight.

3. HOLD BUTTON

   • Short press the button to freeze/release the displayed reading.
   • Press and hold the button to clear the stored data.

4. MODE BUTTON

   • Short press the button to enter the MAX, MIN, and AVG mode.
   • MAX MODE – When in this mode, only the highest (MAX) reading recorded since the button was first pressed will appear on the reading display.
   • MIN MODE – When in this mode, only the lowest (MIN) reading recorded since the button was first pressed will appear on the reading display
   • AVG MODE – When in this mode, only the average (AVG) reading recorded since the button was first pressed will appear on the reading display
   • Press and hold the button to view the stored data, the no. indicator will appear on the right-hand comer of the LCD display, to indicate that it is in the data review mode. Press the or button to view the data one by one.
   • Press and hold the button again to exit the data review mode

5. DIF BUTTON

   • Short press the button to enter P1 and P2 dual channel differential pressure mode. DIF icon will appear on the display.
   • Short press the button again to exit differential pressure mode.
   • Press and hold the button to clear the drift zero. (The data before measurement does not return to zero and without fittings attached to the meter) .

6. UNIT BUTTON

   • Short press the button to select the desired measurement unit.
     This meter offers up to 12 pressure units.

   • Press and hold the button to enter the time setting mode.

   • While on the time setting mode, short press on the button to exit the time setting mode or save the setting.

7. OVER RANGE
   will appear on the display when the pressure reading is over the Maximum range.
   will appear on the display when the pressure reading is below the Minimum range

BASIC OPERATION

1. Short press the button to turn on the meter and select the desired measurement unit by pressing the button.

2. The reading before measurement and without fittings attached to the meter should return to zero. If not, need to ZERO the meter by pressing and holding the button for 3 seconds or until the display shows all zeros.

3. Press and hold the button to enter the time setting if needed. The current setting value will be blinking on the LCD, press the or button to increase or decrease the value. Once the current setting value is done press the or button to move forward or backward to the next value setting. Short press the button to save the setting when all are done.

4. Connect the tubing to the P1, P2 (or both ) input port(s). If both inputs are used (D IF mode ), the meter displays a positive pressure reading if the P1 pressure is greater than P2 and a negative reading if P2 is greater than P1.

5. Short press the button to store the current measured pressure value with a time stamp (can store up to 99 groups ).
   Note that once the stored data reached the 99 groups, it will start to record from scratch (the first group R0 1) if you still press the button to record. The previous records will be cleared up.

6. Press and hold the button to view the stored data, the no. indicator will appear on the right-hand corner of the LCD display, to indicate that it is in the data review mode. Press the or button to view the data one by one.
