4. Shortcut temperature presets
When the machine works right, press key 1, key 2 or key 3 (picture 5), you can get the temperature setted before and use them
for the current working condition. When the machine works right, press key 1 , key 2 or key 3 (> 3 seconds), you can make the
current temperature as the shortcut one and stored at channel! and channel 2 and channel 3.
5. Temperature Calibration
When replacing the heating element or soldering tip, you need to calibrate the temperature, press “▲” “▼”at the same
time(picture 6),enter the mode of setting program, you can see from picture 7
When under the programmable mode, press key” 1 “(picture &), enter the mode of temperature calibration, “CAL” will light and
show the calibrated number last time, see from picture 9 (the calibration number is 0°C)...
Under the programmable mode, press “▲” or “▼” (picture 5), you can adjust the calibrated temperature, the range of calibration
(-50°C ~ 50°C) ( -58°F ~ 122°F). When the real temperature is lower than the display temperature ,enter minus temperature
difference value. When the real temperature is higher than the display temperature, enter the positive temperature difference
value. e.g. real temperature is 200°C display temperature is 220°C, then calibrated temperature is -20°C.
6. Change of the soldering mode
As to the different needs of the soldering mode, AT90DH has three different soldering mode to deal with the different needs,
you don’t need to buy other soldering equipment.
The setting method is as follows:
Press “▲”and “▼” at the same time (picture 6), enter into programming mode (picture 7).
Under programming mode, press “2”(picture 10), enter into soldering setting mode when “Mode” displays, it shows current
working mode. (Picture 11).
Under power setting mode, press “▲” or “▼”, adjust the power, and then press “2” to save. (Picture 12-Mode 1).
