Measurement Techniques

1. Turn the 608BT on by pressing the ON/OFF button. The display will initially read “608” along with the selected unit of measure. After this initial display the 608BT is ready for use.
   Note: Follow these steps to change the unit of measure.
   a) With the 608BT turned off, press and hold the on/off button until the display reads “—-” and the unit annunciator flashes.
   b) Release the on/off button and then press it repeatedly until the desired unit of measure is displayed. The unit of measure will cycle through inH2O, mbar, KPa, and PSI.
   c) Once the desired unit of measure is selected, allow the 608BT to turn off and then turn it back on and proceed with testing. The 608BT will turn on in the last selected unit of measure until changed.
2. Zero the displayed reading by pressing the ZERO button.
3. Connect the 608BT to the device under test.
