(Press “ENTER” key to skip setting relative value). = =
= =.= is displayed on the main display. The relative value
is entered via overlay numbers, press overlay “ENTER”
key to store the relative value, and advance to elapsed
time set mode.

Elapsed time set mode) =.= = = : = = is displayed in sec-
ond and third display. Time (hours, minutes, seconds)
value is entered via overlay numbers, press overlay
“ENTER” key to store time value. Elapsed time starts
from set time value.
9.3 Hi Limit value set mode, (Press “ENTER” key to skip Hi
Limit value set mode), = = = =.= 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 en-
tered 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

thermometer was last in use.
10. T1/T2 T1-T2 second display Input Selection
The input selection indicates which input is selected for
second display; T1 probe, T2 probe or the difference between
the two probes (T1-T2), when the thermometer is turned on,
