The new model has the following new features:  

     1. Real-time temperature display  

     2. Temperature correction (The temperature has been corrected before leaving the factory)  

     3. Adjust the sleep time (default setting is 15 seconds)  

     Technical Parameters  

     Power requirements: DC 16V~24V  

     Interface: DC5.5--2.1 (internal positive and external negative) Do not reverse the positive and negative connections  

     Temperature: 150~450℃ continuously adjustable (the temperature difference is plus or minus 10 degrees)  

     Tin: 5 seconds (24V)  

     The latest version of the soldering iron instructions  

     Enter temperature calibration and sleep setting steps  

     1. Apply DC voltage to the handle (do not insert the heating element), the display shows "EAA"  

     2. After pointing the tip of the soldering iron tip to the "ground", then quickly raise the tip of the soldering iron tip to point to the "sky", you will hear the sound of the gravity switch in the handle. At this point, start counting the blue light on the handle flashing 7 times, and then quickly turn it on for the second time. Point the tip of the soldering iron tip to the "ground" (don't shake it), then immediately point to the "sky", and then point to the "ground" again after the count blue indicator flashes 7 times. At this time, the temperature correction digital tube will display "000", the tip of the soldering iron will point to the "ground", and the "sky" digital tube will increase by one. If the handle is still or the soldering iron head points to the "ground" for 3 seconds, it will automatically enter the sleep time setting, the digital tube will display the initial value "15" and the soldering iron head will point to the "ground", and the digital tube will increase by 1 second. Sleep time can be set to 99 seconds  

     Temperature correction method (corrected temperature can only be changed to a negative value. Do not correct if it is not necessary. Because the temperature has been corrected before leaving the factory)  

     1. Insert the heating element into the handle and turn the knob to make the digital tube display a value of 300 or greater  

     2. Use a temperature corrector to test the actual temperature of the heating core and write down the temperature "xxx" at this time  

     3. Refer to the steps of entering temperature correction settings to enter the temperature settings, the digital tube displays "000"  

     4. The value set by the digital tube = the temperature tested by the temperature tester-the temperature set by the digital tube;  

     For example: the temperature set by the knob is 260, and the actual temperature of the soldering iron tip tested by the thermometer is 300  

     Then, after entering the digital tube, change "000" to "040", that is, 300-260  

     Sleep time setting method  

     1. After entering the temperature setting, the soldering iron tip will stand still for 3 seconds, waiting for it to automatically enter the sleep time setting  

     2. The initial value of entering the sleep time is 15 seconds, and the maximum value can be set to 99 seconds.  

     About the digital tube display "EAA" instructions  

     1. The heating element is not inserted, the contact is poor, and the heating element is blown  

     2. When the school heating core temperature is below 150 degrees  

     (Including the value subtracted during manual calibration, for example: the actual temperature of the heating core is 200 degrees, we set it to 60 in the settings, then the actual temperature after calibration is 140 less than 150. At this time, the digital tube displays "EAA")
