Operating instructions
7.3
Continuity check for i-Tool
If the soldering tip is not heated up after the previously mentioned points have been
checked, you can check the heater resistor and the temperature sensor with an
ohmmeter for conductance.
7.3.1 Heating element
The continuity resistance between measuring points
a
and
b
should be approx.
3,5 - 4,5 Ohm (at cool soldering iron). In the event of interruption, the heating ele-
ment is to be replaced (
g
= potential equalization).
7.3.2 Thermocouple
There should be approx. - 3 Ohm continuity resistance between measuring points
c
and
d
If the continuity resistence is higher, the tool has to be repaired.
With a measuring at the plug (heating element must be mounted in the soldering
iron) there should be approx. 3,8..5 Ohm between measuring points
e
and
f
.

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 6.4.3 “Password lock”).
