PUMP:
This menu item allows the user to select
REG FLOW
(regular flow) or
HIGH FLOW
for the pump. Regular flow sets the pump flow rate to
approximately 0.3 LPM default. High flow increases the flow rate and
should be used when a hose/probe is attached. The higher flow rate
helps to overcome the resistance of the hose and probe to maintain
at least 0.5 LPM flow into the instrument. Using the ARROW DOWN
button, scroll to the desired setting and push the MENU button to
accept.
PASS CODE:
This menu item allows the user to set a security pass code to prevent
other people from changing the instrument settings. Pressing the
MENU button at this option takes the user to the pass code set up
screen. The user is required to enter the existing pass code first. Use
the ARROW UP or ARROW DOWN buttons to input the existing pass
code then push the MENU button. The display then indicates it is
ready for a new pass code to be entered. Use the ARROW UP or
ARROW DOWN buttons to set the desired numbers for a pass code.
Pressing the MENU button at this point saves the new pass code.

The PASS CODE can be reset to the factory default value of
1234 by using the
