=.= is displayed in main display, Hi Limit value is
entered via overlay numbers, then press “ENTER”
key to store the Hi Limit value. = = = =.= is displayed
in main display, Lo Limit value is entered via overlay
numbers, then press overlay “ENTER” key to store
the Lo Limit value and exit SET mode.
9.4 When the thermometer is turned on it uses the relative
value and Hi/Lo Limits values that were entered when
thermometer was last in use.
10. Relative value Recall display mode.
Press REL RECALL key to display the Relative set value
on second display. Press REL RECALL key again to exit
this mode.
11. Hi/Lo Limits value Recall display mode
Press Hi/Lo RECALL key to display the Hi set Limit
value on second display. Press Hi/Lo RECALL key again

Press Hi/Lo RECALL key again to exit this mode.
12. Hi/Lo Limits mode (Main display)
Press “Hi/Lo Limits” key to enter the Hi/Lo Limits com-
parative mode, is displayed. When the input tem-
