 Operation  

  1. Power

 Press the ON/OFF button to turn power on or off. The meter will perform a short self-test when turned on. The meter defaults to the setting used during the last operation.

  1. Zero Adjust and Offset

Before use and without fittings attached to the meter, press the HOLD button for more than 2 seconds to zero the meter. The meter will reset and display “000” from right to left. 0.000 will be displayed.

If you desire to offset the meter and display, press the DIF button while taking a measurement subsequent reading will be the difference between the current measurement and the measurement that was on the display when the DIF button was pressed.

  1. Data Hold

Press the HOLD button momentarily to freeze the displayed reading. The HOLD icon will appear on the upper left-hand side of the display. Press the HOLD button to again to return to normal operation.

  1. Record

The MAX/MIN mode allows the user to view only the highest (MAX), lowest (MIN), or average (AVG) readings with relative time stamp.

  • Press the REC button once and REC appears on the display. The relative time clock also appears in the secondary display and starts counting.
  • Press the REC button again and MAX appears on the display. The display is now showing the maximum pressure and the relative time it was recorded.
  • Press the REC button to display the minimum MIN reading with the relative
  • Press the REC button to display the average value AVG reading with the relative time.
  • Press the REC button again to continue recording MIN/MAX/AVG measu
  • To exit the MIN/MAX/AVG mode, press the REC button for 3 seconds to return to normal operation.
  1. Backlight Display

Press the Backlight button to turn on the backlight. It will remain on for 40   seconds.

Press the Unit button momentarily and the meter will cycle through the 11 available units of measure as indicated by the cursor on the button of the display.

 Error Codes

An error message will appear on the display if the meter fails an internal diagnostic test.

  1. Err.1: Pressure value over the range.
  2. Err.2: Pressure measurement range is the following.
  3. Err.3: DIF function, the differential pressure value is over range.
  4. Err.4: DIF function, the differential pressure value is below range.

 Battery Replacement

When the battery power is low, “BAT” will appear on the LCD. Replace the 9 W battery.
