FieldFox High Temperature Protection
High-Temp Shutdown Warning (RTSA Mode Only)
In extreme situations, Temperature Control mode may not stop an increase in
the FieldFox internal temperature. Just prior to shut down, the FieldFox will
display a warning of imminent shut down and the instrument turns off. At
above approximately 77°C, a Maximum Auto Protect message—(Top
"WARNING..." message) displays for 9 sec. Red text at left bottom corner of
display remains on until internal temperature returns to ~75.5°C. At above
~78°C, High-Temperature Shut down will engage and turn OFF the FieldFox.
Refer to Figure 2-3. See also, Table 2-1 on page 26.
