Sensor Error
When there is the possibility that a failure has
occurred in the sensor or heater (including the
sensor circuit),
is displayed and the power
is shut down with the buzzer sounding
continuously.
CAUTION:
The sensor error also occurs if the tip is not inserted
properly. Once the tip is inserted properly, the HAKKO
941 is restarted.

Low-temperature alarm
tolerance error
If the sensor temperature falls below the dif-
ference between the current temperature
setting and the low-temperature alarm
tolerance,
is displayed and the warning

to a value within the set tolerance, the buzzer
will stop sounding.

EXAMPLE:
Assume that the temperature setting is 400°C./750°F.
and the tolerance 50°C./100°F. If the temperature
continues to decrease and finally falls below the value
indicated below while the heating element is on, the
displayed value starts blinking to indicate that the tip
temperature has dropped.
