YIHUA 938D

Main function

1.Three memory sections:CH1/CH2/CH3, each storage segment can store three temperature.

2. Sleep function , Automatic shutdown function , Celsius / Fahrenheit function
a), Sleep function soldering iron automatic detection of their work status are not in use in a quiescent state, arriving to set the sleep time, the temperature of the iron automatically lower the temperature to 200 ° C enter into sleep state, can effectively prevent the oxidation of iron head and prolong the iron tip service life, energy saving and environmental protection. The sleep time can be set range 0 to 99 minutes in 1 minute steps, users can be set based on usage, if you do not need a soldering iron sleep ,the sleep time is set to 0.
b) Automatic shutdown function after soldering iron enter into sleep state, start the timer program, set the shutdown time did not wake up from sleep, automatic shutdown, energy saving and environmental protection. Auto power off time setting range 0 to 99 minutes in 1 minute steps.
c) Celsius / Fahrenheit temperature display function designed to meet the market needs of the different regions of the temperature display mode.

3.Temperature correction function:

Adapted to the environmental impact or replacement heater, iron top parts 
caused by iron temperature and display temperature deviation can be corrected by this function, the calibration temperature range: -50℃~ + 50 ℃
