DIY requirements and risks: DIY technical requirements,the soldering station does not provide the circuit diagram and schematic diagram,after purchase contact to obtain the installation wiring diagram,therefore,the proposed ,bird please consider,I can only provide welding related guidance,all devices ,Once welded,will not be returned,DIY risk Participants to assess their own ability and risk,problems and risks themselves. STM32-OLED digital display T12 soldering station simple instructions First, the main function of welding station and performance characteristics:1, temperature range 150 ~ 480 2, the thermocouple cold junction temperature automatic compensation range-9-99 (to be more accurate).3, temperature control, temperature stability 2 (no load). 4, can save 5 groups of temperature.5, can save the temperature of each head calibration parameters, support all types of T12 head, and there are six custom head, can shield the less common head (in the tip management allows you to use the head). 6, the automatic standby (time 1-60 minutes can be set).7, automatic sleep (soft shutdown) (time 1-60 minutes can be set).8, the latest version 2.1S comes with clock, voltage display, cut-off voltage settings and other functions. Second, the main operation: 1, under normal circumstances, 1 second continuous counter-clockwise rotation 3 cells into the standby (default 200 degrees (150-300 degrees can be configured) state, if the set temperature is 200 degrees directly into sleep. 1.1 Standby state, 1 second continuous counter-clockwise rotation 3 sleep (soft shutdown), sleep (soft shutdown) state, short press the encoder to enter the working state. 1.2 Standby mode, press the encoder or clockwise rotation to restore the working state.Out of a . 2, under normal circumstances, 1 second clockwise rotation 3 consecutive grid into the power to enhance the current temperature +50 degrees (10-200 degrees can be configured), after 5 minutes (1-60 minutes can be set) after the automatic reply, It is also possible to recover the encoder in advance with any operation. 3, under normal circumstances, short press to enter the temperature setting state. 3.1 In the temperature setting state, the temperature of the current setting group can be adjusted by encoder, the default step is 5 degrees (step 1-50 can be set). 3.2 In the temperature setting state, press and hold the encoder and rotate to switch the setting group. 3.3 In the temperature setting state, short press the encoder to save and exit to normal. Color: As Shown Material: PC+ metal Package Contents: 1 x Temperature Controller Kit(Normal version) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
