Error Diagnosis and Troubleshooting
Continuity check for thermocouple
There should be less than 25 Ohm continuity resistance between measuring points 7 and
3. If the continuity resistance is higher, the tool must be repaired.
Continuity check for MICRO TOOL and CHIP TOOL
The continuity resistance between measuring points 1 and 6 should be between 8 Ohm
(at low temperature) and 25 Ohm (at max. temperature).
Parameter changes not possible
If the station is protected by a password, the parameters only can be changed by entering the
correct password. (see chapter 5.3.7 Password Function).

Description of error
Calibration values damaged
Sensor cold junction temperature/cable defective.
Tool cannot be identified.
Thermo-sensor/cable defective/overheated.
Heating element/cable defective/overheated.
Set parameter damaged.
•
The station permanently displays only the room temperature. In this
case, there is a defect in the heating element or cable with thermocou-
ple-controlled soldering irons (POWER TOOL, TECH TOOL).
•
The station permanently displays an actual temperature that is too high.
This error can occur during operation of CHIP TOOL. In this case, switch
off the station and replace the tool with an intact one.
