o Set Power_Off time: This menu option allows the user to change the
amount of time allowed to lapse between the last key press and meter
shut-down. Allowable range is 1min – 9min, with a default value of 2min.
o Set Backlight: This menu option allows the user to change the amount of
time allowed to lapse between the last key press and backlight shutdown.
The default setting for this feature is “NO”, where the backlight is
completely disabled. Backlight shutdown delays are 10, 20, 30sec. It is
recommended that the backlight delay be set to the minimum amount of
time necessary in order to maximize battery life.
o Conversions: This menu option allows the user to change the
temperature scale: Fahrenheit (default) or Celsius and the electrode type:
the default 4-pin (or non-insulated) or 2-pin insulated.
NOTE: Except for clock settings, all other parameters will return to their
default values, as indicated above, when the “RESTORE DEFAULTS”
option is selected in the Storage Menu. The values chosen for the Setup
Menu parameters will remain in effect even if the meter is turned off, and
even if the battery is removed.
