How to input the soldering iron head correction value to 942T
When entering the third digit, use the "UP" or "down" button to determine a
positive or negative number. Select 1 for positive numbers and 0 for negative
numbers.
This method requires the use of a soldering iron thermometer to measure the
temperature of the soldering iron tip and the most correct process control:
1. Insert the card into the card hole.
2. Press and hold the button # for one second.
3. Use a soldering iron thermometer to measure the soldering iron tip temperature.
When entering the correction value input mode, the soldering iron tip
temperature is controlled with a correction value of 0 regardless of the value
of the correction value.
4. Enter the correction value
Detect 400 ° and soldering iron measuring temperature, record this value. Refer
to the above example to determine the correction value of the input required for
the soldering iron tip.
If the measured temperature is 395 degrees Celsius, the temperature difference is
+5 degrees Celsius and the soldering iron head is slightly colder than five
degrees, so the correction is +5 degrees Celsius.
If the measured temperature is 405 degrees Celsius, the temperature difference
is -5 degrees Celsius, the soldering iron head is slightly hot five degrees, so the
correction value is -5 degrees Celsius.

A. Always turn off the power every time you remove or insert the soldering iron.
B. Place the soldering iron tip on the soldering iron head bracket.
C. Insert the new soldering iron head into the end.
If not fully inserted, a sensor error S-E will be displayed when the power is
turned on.
example:
If the measured temperature is 395 degrees Celsius, the temperature difference
is +5 degrees Celsius and the soldering iron head is slightly colder than five degrees,
so the correction is +5 degrees Celsius.
If the measured temperature is 405 degrees Celsius, the temperature difference
is -5 degrees Celsius, the soldering iron head is slightly hot five degrees, so the
correction value is -5 degrees Celsius.
When changing from 350 degrees Celsius to 400 degrees Celsius.

Soldering iron head maintenance:
(1.) Soldering iron head temperature
(2.) Clean up
(3.) After use
(4.) When not use
(5.) Inspection and cleaning
Excessive temperatures can shorten the life of the soldering iron tip and can
cause enthusiasm for the components. Always use as low a temperature as
possible during soldering. The 942T has excellent temperature recovery
characteristics to ensure effective low temperature soldering.
Wipe the soldering iron oxide or old tin scraps before soldering. Use a clean,
damp cleaning sponge (provided by the 942T) or a 599B soldering iron cleaner.
After soldering, oxides and carbides derived from the residual flux of the
soldering iron tip can damage the soldering iron tip, causing soldering iron
errors or reducing the thermal conductivity of the soldering iron tip. When the
soldering iron is used continuously for a long time, the soldering iron tip should
be opened once a week to remove oxides to prevent the soldering iron head
from being damaged and the temperature to be lowered.
After use, the soldering iron tip should be wiped and coated with new tin shavings
to prevent oxidation of the soldering iron tip.
Do not set the soldering iron to a high temperature for a long time. The solder
plating layer of the soldering iron tip is covered by the oxide to deteriorate the heat
conduction. Please turn off the power. If it is not used for a few hours, it is best to
unplug the power cord.
If used daily, please check and clean up the life of the soldering iron.
a. Set the temperature to 250 degrees Celsius.
b. When the temperature is stable, wipe with a cleaning sponge (refer to 2. above)
to check the condition of the soldering iron. If the soldering iron tip has been
deformed or worn out, replace it.
c. If the tinned portion of the soldering iron has black oxide, it can be plated with
new tin shavings and then wipe the soldering iron tip with a cleaning sponge.
The cleaning is repeated in this way until the oxide is removed at the bottom,
and then new tin shavings are applied.
d. Turn off the power and remove the soldering iron tip with a heat-resistant
gasket. Place it to cool it.
e. If the color of the flux residus attaching to the soldering tips turns yellow,
it can be wiped with alcohol or the like.
Do not use a file to set off the oxide.
● sensor error
● The lower limit sets the temperature error
● soldering iron connection error
If any part of the sensor/heating element (including the sensor
circuit) fails, the error mark 4 is displayed and the current delivered
to the soldering iron is stopped.
Sensor errors can also occur when the soldering iron tip is not fully
inserted. Insert the soldering iron head again and start again.
Set the temperature to 400 degrees Celsius. The low
temperature warning limit is 50 degrees Celsius. Although the
heating element has been energized, the temperature continues
to drop. The display will flash, indicating that the soldering iron tip
temperature has dropped.
example:
If the 907 or 908 to 942T soldering iron tomb is connected, the
soldering iron connection error will be displayed.
Be sure to unplug the power cord before checking the inside of the
942T or replacing parts, otherwise it may cause electric shock.
