CHT-100 Operations & Installation Manual – Ver. 1.9 – June 5, 2003
L(Low Temperature Limit Set)
The low temperature limit should be set to the manufacturers recommended low
limit for correct operation. This setting determines the point at which the bar
indicator will begin to turn on. Values for this setting can range from 200ºF to
400ºF.
Moving the A M S switch to the Aposition and holding it there will allow the
temperature to increment. Initially the increment will be at a slow rate and then
speed up to a faster rate for easy selection. Once the increment is in the fast
mode it can be slowed again by moving the A M S switch once to the Mposition
and then back to the Aposition. Once the maximum (400ºF) has been reached
the count will start over at 200ºF.
Once the correct temperature has been reached, by moving between the Aand
Mpositions of the A M S switch, move the A M S switch once to the Sposition
and release. The low limit will now be saved and applied to all cylinders. The
display will move to the next parameter.
H(High Temperature Limit Set)
The high temperature limit should be set to the manufacturers recommended
high limit for correct operation. This setting determines the point at which all bars
on the bar indicator will turn on. Values for this setting can range from the low
limit plus 20ºF to 700ºF.
Moving the A M S switch to the Aposition and holding it there will allow the
temperature to increment. Initially the increment will be at a slow rate and then
speed up to a faster rate for easy selection. Once the increment is in the fast
mode it can be slowed again by moving the A M S switch once to the Mposition
and then back to the Aposition. Once the maximum (700ºF) has been reached
the count will start over at the preset low limit plus 20ºF.
Once the correct temperature has been reached, by moving between the Aand
Mpositions of the A M S switch, move the A M S switch once to the Sposition
and release. The high limit will now be saved and applied to all cylinders.
DonE
The display will now show the characters DonE and the instrument will restart. At
this point you have completed all the setup and configuration of the instrument
and it is ready for service.
