Wireless large screen melting thermometer

1、 Purpose:
The wireless transmission technology of the W660 wireless large screen melting thermometer synchronously and accurately transmits the temperature values measured by the handheld thermometer to the wall mounted large screen display through wireless transmission technology, eliminating the constraints of the wall mounted large screen thermometer connection and improving the anti-interference ability of the instrument.
This instrument, when paired with suitable thermocouples, can perform precise and rapid temperature measurement in various situations.

thermocouple	Model number	Measurement range (℃)	Suitable occasions
Single platinum rhodium	KS－602	0~1750	Liquid steel, iron, and copper
Single platinum rhodium	KR—602	0~1750	Liquid steel, iron, and copper
Double platinum rhodium	KB－602	500~1800	High temperature molten steel
Tungsten rhenium	KW－602	0~2000	Steel and molten iron
Nickel chromium nickel silicon	K	0~1000	Aluminum and zinc liquid

2、 Characteristics
The W660 wireless large screen melting thermometer combines the flexibility of a handheld thermometer with the remote visibility of a wall mounted large screen instrument, eliminating the need for a connection between the handheld testing device and the large screen display.
This instrument consists of a handheld melting thermometer with wireless transmission function and a large screen display with wireless reception function (using a 5-inch digital tube display: character height 128mm). It has the functions of synchronous light indication, electric bell sound prompt, and automatic maintenance of temperature measurement value at the end of temperature measurement, as well as alarm functions such as disconnection, over range, and power undervoltage.
This instrument adopts an original imported professional data transmission module to ensure highly reliable wireless transmission of measurement data.
This instrument can be equipped with 5 types of thermocouples on the same machine. This instrument has excellent anti-interference ability due to the use of the latest anti-interference measures. When the intermediate frequency furnace is powered on for melting, temperature measurement can be carried out inside the furnace without cutting off the power.
This instrument can store 1000 sets of historical data and can be optionally equipped with a printer.

4、 Operating instructions
1. Operation of wireless transmission portable melting thermometer
Press the power switch (ON/OFF) on the panel, and the display immediately shows "", followed by the thermocouple model/S type,/B type,/WRe3/25,/K type,/R type.
When the thermocouple is not plugged in, the instrument displays "". When the thermocouple is plugged in and in good contact, the instrument displays the ambient temperature (the instrument with the B division mark displays ""), and temperature measurement can be performed at this time. Insert the thermocouple into the molten metal at a depth of ≥ 20mm during temperature measurement, ensuring fast, accurate, and stable operation. When the indicator light (H) is on (with sound and light prompts), the temperature measuring handheld should be immediately lifted (usually for 3-5 seconds). The instrument automatically displays and maintains the measured temperature value.
At the same time as the temperature measurement is completed, the instrument automatically transmits the signal to the large screen display. After the large screen display wirelessly receives the signal without error, it displays the same temperature value as the wireless transmission handheld melting thermometer. At the same time, the electric bell sound prompts to lift the test handheld.
2. Operation of large screen display screen
Turn on the power switch, and the display will show the current time; When a signal is detected, it automatically receives the display and maintains the temperature value.
(1) Historical data query
This instrument can store 1000 sets of historical data.
Press the "Query" button, and the instrument will enter the historical data query state. At this point, the large screen displays the current year; According to the query requirements, press the "↑" and "↓" keys to make corrections.
For example, to query such data: the temperature value measured at 09:08 on December 10, 2008 was 1678 ℃;
At this point, the query steps are as follows:
a、 Press the 'Search' button to display the current year; Press the "↑" and "↓" keys to correct to display 2008;
b、 Press the "→" key again to display the current month, and press the "↑" and "↓" keys to correct it to display 12;
c、 Press the "→" key again to display the current day, and press the "↑" and "↓" keys to correct it to display 10;
d、 Press the 'Confirm' button to display 2008 1210 0908 1678 in sequence;
At this point, press the "↑" and "↓" keys to search for the previous and next data of the temperature value.
If the instrument does not respond when pressing the "↑" or "↓" keys, it indicates that the data query has been completed; Press the 'Query' button again, and the instrument will exit the query state.
(2) Print
Connect the printer data cable plug to the printing interface of the large screen display, connect the printer power supply, and the printer will automatically print the displayed data every time the large screen displays it. The printing format is as follows (such as January 18, 2010 at 08:08:1678 ℃):
2010－01－08 08：08 1678
5、 Installation
The large screen display should be installed within a linear visible distance of 10-50 meters from the temperature measurement point, which is more suitable for observation and recording. The installation position should be 2-4 meters above the ground, and there should be no object obstruction at the receiving antenna of the monitor; Pull the rod antenna to the longest length; The monitor power supply is AC220V (using lighting circuit power supply, grounding must be reliable).
