SYSTEM INITIALIZATION
The 21-19650 is an advance system which uses a newly devel-
oped temperature sensing method. Therefore it is important that every
time a new pen is plugged into the machine this system initialization
routine and Tip calibration procedure be followed.
1. Ensure that unit is turned off.
2. Plug Soldering iron into its socket. Make sure the tip of the soldering
iron is at room temperature. (between 20 to 30 C)
3. Press and hold the SET button while switching the unit on. Wait for
the display to show three zeros “000” before letting go of the SET
button.
4. After a few seconds the display would switch to 350C, which indi-
cates the pen has been successfully registered into the machine.
The next step is to calibrate the tip temperature.
C. CALIBRATING TIP TEMPERATURE
The tip should only be calibrated at a set temperature of 350C.
Calibrating at this level will ensure correct temperature in all
temperature level settings.
1. Set temperature to 350C. Measure the tip temperature through an
external temperature reader with a thermocouple as its sensor. En-
sure the external temperature reader’s sensor and the solder iron’s
tip can keep good physical contact. Wait for the display to reach the
set temperature of 350C, then allow the tip to idle at the sensor for
60 seconds for proper temperature measurement.
2. Press and hold the SET button to enter the system configuration
mode. Wait for the display to change to a number with an “A” as its
prefix. This denotes that we are now configuring the digital offset of
the system. A display like “A000” indicates that the digital offset is
currently set at neutral.
3. Press the increase and decrease button to adjust the digital offset. A
negative number denotes a negative offset and a positive number
denotes a positive offset.

5. Adjust the offset number until the external temperature sensor
reading is equal to our set temperature of 350C.
6. Repeatedly press the SET button until the display shows the word
“SAVE”. Press the increase button to save and exit from the system
configuration mode.
7. The tip has now been properly calibrated.
8. Saved settings are stored into memory and will remain in effect un
less changed by the user.
D. TEMPERATURE CONTROL
1. Turn the power ON.
2. The display would show a number between 200 to 480 indicating
the set temperature. Default setting is at 350C
3. After a few seconds the display would then switch to showing the
actual temperature.
4. To Increase or decrease the temperature, press the temperature
control increase or decrease buttons.
5. Temperature control range is from 200C to 450C.
D. QUICK JUMP FEATURE
The system has two configurable quick jump settings. The quick
jump features enables the user to easily jump to a predefined tempera-
ture level. The two most frequently used temperature level must first be
saved into system memory. A simple push of two button will automati-
cally jump to these preset temperature level.
To configure these two temperature level:
1. Press and hold the SET button to enter the system configuration
mode.
2. Repeatedly press the SET button until the display shows a number
with “b” as its prefix. This denotes that we are now configuring the
first quick jump setting.
