Instructions
1. Open the battery cover on the back of the instrument, insert the battery and close the back cover. Please
pay attention to the correct connection of the battery when inserting the battery.
2. Put the sensor into the putter and terminal (red edge into the red terminal, blue into the blue terminal).
3. Press the power and check the display screen. When the display shows room temperature, you can perform
operation or measurement.
4. The soldering iron tip sticks the flux to the test point, and the temperature will be displayed within 2 seconds.
5. After use, press and hold the power button to shut down.

Precautions
1. The sensor is made of very thin (φ0.2mm) metal wire. It should be used with care and not bend or break.
2. The housing of the thermometer is made of plastic. Do not touch the tip of the soldering iron.
3. The sensor is a consumable item (life of about 50-60 times), long time use, the alloy layer is worn out, the
measurement will be inaccurate, and need to be replaced New sensor.
4. Alcohol can be used to clean the flux attached to the terminal. Do not use thinner or volatile oil.
5. If the display shows -1, it means that the temperature sensor has been scrapped (or no sensor is installed)
and a new one needs to be replaced.
6. If it displays , it means the battery is low, and the temperature cannot be measured normally, and the
battery needs to be replaced. It is recommended remove the battery if not to use it for a long time .
7. The 191-212 temperature sensor is only suitable for measuring the temperature below 500℃, such as
measuring higher temperature, please use the appropriate Temperature probe.
8. Do not blow the hot air gun directly to the ST-1090 for measurement. Blowing directly will damage the
ST-1090 host.
Note: Thermocouple and external temperature sensing wire cannot be used at the same time.

Operation guide
一.Switch function
Short press the "POWER" button to turn on, the display shows the room temperature when turning on;
you need to long press the "POWER" button to turn off.
七.Automatic shutdown function
Figure7-1
When the thermometer is not in use, it enters the shutdown countdown until the set shutdown time
(default 15 minutes, can be set), the thermometer automatic shut-down.
Long press the "MAX HOLD" key to enter Figure 7-1, the "POWER" key shortens the time, and the "SEND"
key extends the time (time setting range 1~240 minutes). After the setting is completed, long press
the "MAX HOLD" button to exit and return to the working interface.
OFF
八.Temperature unit switch setting interface
Long press the "MAX HOLD" key to enter Figure 7-1, press the "MAX HLOD" key again to enter Figure 8-1,
and press the "SEND" key.Switch ℃/℉; after switching, press and hold the "MAX HOLD" key to exit and return
to the working interface.

三.The display interface of the number of times the sensor wire is used
Each time the temperature is tested, the upper right display area of the main window will increase the
number of times, up to 999 times, long press "RESET"The combination key can be reset to zero times.
(When used 50 times, it flashes to prompt to replace the sensing wire)
六.The sensor wire is damaged or there is no sensor wire display interface

After testing the temperature, short press the SEND key to send the data, the IR
character will be displayed as shown in Figure 4-1 (support ST-3150 soldering station)
The serial port data line is connected to the thermometer and the computer, the thermometer displays COM
as shown in Figure 4-2; the thermometer sends to the computer every 100ms temperature data.

五.Low battery display interface
When the battery power is low, the low battery symbol is displayed in the upper left corner, prompting that
the battery needs to be replaced as soon as possible to avoid affecting the use (Low battery temperature
measurement is not accurate).
