To adjust the start pressure of the ramp on your Z1™ and Z2™ your ramp time must be set first.  If there is no set ramp time, a Fail 2 message will appear on your LCD display.

To set the ramp time:

1.  With the Z1™ or Z2™ in standby mode, press and hold the UP Arrow Button for approximately 3-5 seconds.  

     When "0.0" begins to flash, press the UP Arrow Button to select the amount of time you would like the ramp 

     feature to be engaged.  It can be set from 5 minutes to 45 minutes, in 5 minute increments.  

2.  When your time is selected, press and hold the Start/Stop Button until you see the word "Accept".  

     Now the ramp feature is engaged and you can proceed to set the ramp pressure.

To set the ramp pressure:

1. With the Z1™ and Z2™ in standby mode, press and hold the Down Arrow Button for approximately 3-5 seconds 

    until the 4.0 (or another pressure reading) begins to flash. 

2. While the start pressure value is flashing, repeatedly press either of the Up/Down buttons to increase or decrease

    the start pressure (4.0 is the lowest setting).

3. When the desired ramp start pressure is reached, press and hold the Start/Stop Button for approximately 3 seconds 

    (until you see the word Accept) to save your setting. (This setting will be saved even when the Z1™ or Z2™ is not 

    powered on). The Z1™ or Z2™ unit will then return to the standby mode.

NOTE: To return to standby mode without saving the new setting, press and release the Start/Stop Button momentarily instead of holding it down.
