STEP #3
a) The screen should say "Connect a 1.255 K ohm resistor..."
b) Place the 80° C (1.255 KΩ) plug into the
Temperature Reference] between 191 and 203?
Yes Between 191 and 203! 'Sharply press 'CONFIRM' then see STEP #4 (page 303).
No NOT between 191 and 203! ENSURE the 80° C plug is placed properly at the
the left! If okay, see procedure number
STEP #4
a) The screen should say "Connect a 0.915 K ohm resistor...".
b) Place the 90° C (0.915 KΩ) plug into the
Temperature Reference] between 204 and 216?
Yes Between 204 and 216! Save the calibration then proceed to

T- 7.1.0 ERROR DURING TEMP SENSOR CALIBRATION

Perform this procedure if (and ONLY if) "Operator Error" OR "Actuator Board Error" banner occurred OR a
[Pre-Temperature Reference] value was not in range.
a) Turn the machine OFF!
b) Using a different FOUR-RESISTOR SET return to (ABOVE) procedure number
HOWEVER, if you return here see part c.
c) Read before performing! With the machine off, one at a time, swap in the listed components (see
COMPONENT LIST below), with known good then, in between, return to (ABOVE) procedure number
T- 7.0.0 (page 302) to test each new component until the error banner does DOES NOT occur.
