CHT-100 Operations & Installation Manual – Ver. 1.9 – June 5, 2003
4. SETUP
Once installed your instrument will require setup to match the specific engine
parameters as well the user defined preferences.
Instrument setup is only required when a parameter or display configuration is to
be changed. With proper planning you should only have to perform this function
once in the life of the instrument. All information is stored in the instruments
lifetime memory, which will be retained without battery power for up to 100 years.
To enter
SETUP
mode turn off all power to the instrument. Next press and
HOLD
the
A M S
switch in the
S
position and turn on the power to the instrument. Hold
the switch in this position until
SEt-
is displayed. At this point release the switch.
NOTE: When in the setup mode the display bar will remain blank. The CYL
digit and the four digit display shows the parameter value and type as per
the enclosed instructions.
In order to set the manufacturer specified limits for your engine you will require
the manufacturer specified high and low limits. Please refer to your engine
operator’s manual for this information. Most engines will operate between 350ºF
and 435ºF.
