ersa DIGITAL 2000 A
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).

Error Messages
The DIGITAL 2000 A carries out an automatic error diagnosis. The result of a diagnosis
is outputted as an error code. The string ‚Err‘ then appears as the first three characters
of the display. At the same time, the error code is displayed as the fourth character. The
error codes are listed in Table 9. Error messages may also be confirmed with the control
buttons.

Other Errors
Other errors may also occur, indicating possible defects in the soldering tool.
These errors are:
• 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.
