3 Technical Specifications

4 panel

There are three measurement indicator lights on the panel: Ready, Measure, End, and three setting keys:K1TheK2andK3.

5 Indicator lights and alarm horn control output instructions

When there is no measurement or the thermocouple has not been inserted, the thermometer displays the current time, and all three indicator lights are not on. After inserting the thermocouple, the green light is on. After inserting the thermocouple into the molten steel, the yellow light is on. When the measurement is successful, the red light is on, and an alarm control output is triggered; If the measurement fails, all three lights will be on.

After the test is completed, the test results show180Minutes, the horn rings5secondThe horn is activeDC12VOutput. The principle wiring is as follows:（With voice reporting, this function is not available

6 Specific operation instructions for setting keys and dials

There are three keys on the front panel of the thermometerK1TheK2andK3Used to set the date, time, and operating parameters.K1The key is used to select the parameter item to be set (specific item numbers are shown in the table below),K2Used to select the bit to be set,K3Used to input specific parameter values.

If the thermocouple has already been inserted and is in the preparation or measurement state, the button will not work. Only when the thermocouple is not inserted can the button be used for setting operations. First pressK1Press the key to enter the setting state. In the setting state, the leftmost digital tube displays the setting number, and the two digital tubes on the right display the setting value. In the setting value, the current editing position is flashing. PressK3Enter the size of the value to be set, pressK2The key can change the editing position. After setting a setting item, pressK1Enter the next set number.

The four characters displayed on the panel, with the leftmost two characters being the setting item number. The second character on the left is not displayed, and the third and fourth characters on the left are set values.

Setting items11To set the communication address, it can be configured as1～99.

Setting items12To set the communication baud rate, it can only be set to1～4，1Indicate baud rate bit1200，2Indicate baud rate bit2400，3Indicate baud rate bit4800，4Indicate baud rate bit9600.

In the set state, ifIf there is no button operation for 10 seconds, the system will automatically return to normal operation.

Internal dial setting instructions:

There are circuit boards inside the chassisThe four dials SET1, SET2, SET3, and SET4 are described as follows:

(NonWhen ON, it is OFF

SET1: The first and second bits are used to set the division marks

1

The third digit of SET1 is the voice signal switch, which is activated when turned on

The fourth bit of SET1 is the fast/continuous measurement setting, and when 4=ON, it is in the fast temperature measurement state

SET2: Temperature fluctuation value △ T setting

第The first digit represents 1, the second digit represents 2, the third digit represents 4, and the fourth digit represents 8

For example, set the fluctuation value to12 ℃, as follows: 1=OFF 2=OFF 3=ON 4=ON

Set the fluctuation value to8 ℃, as follows: 1=OFF 2=OFF 3=OFF 4=ON

SET3: Platform fluctuation effective time setting, unit is 1/6 second

第The first digit represents 1, the second digit represents 2, the third digit represents 4, and the fourth digit represents 8

For example, set the fluctuation value to3/6 seconds, as follows: 1=ON 2=ON 3=OFF 4=OFF

Set the fluctuation value to4/6 seconds, as follows: 1=OFF 2=OFF 3=ON 4=OFF

SET4 is reserved.

7 How to use buttons to query historical temperature data

In the non set state, pressK2Press the key to enter the historical temperature data query state. If there is currently no historical measurement data, the screen will display "--"; Otherwise, the historical temperature data will start to be displayed, with the latest measurement data displayed first, every time you press itK2Press the key to refresh and display the next screen of data. When the oldest historical temperature is displayed, press it againK2Press the key and start displaying the latest history again, that is, loop display.

pressK3Key to exit the historical temperature data query state and return to normal operation state

InstructionsEach measurement record needs to be displayed on three screens. The first screen displays the month and day, the second screen displays the hour and minute, and the third screen displays the temperature value. When the first screen is displayed, the green light is on; When the second screen is displayed, the yellow light is on; When the third screen is displayed, the red light is on. After each screen displays for about two seconds, it automatically switches to the next screen.

In the query state, ifIf there is no button operation for 10 minutes, the system will automatically return to normal operation.
