Đồng hồ điện tử đèn led tích hợp đo nhiệt độ thiết kế cỡ lớn

Giới thiệu Đồng hồ điện tử đèn led tích hợp đo nhiệt độ thiết kế cỡ lớn

The goods look the same as the old version, different, chips Different

Product characteristics:

1: Ultra small volume, patterns: 40.2 long and broad 12.8 mishap

2: Settlement time、 temperature、 voltage serves the function of a single body. Roster function can be switched at any time.

3: A total of 4 display modes. Temperature only shows Time 2 show Temp 3 show voltage only at 4 time.

4: Manual correction function of the temperature error of the merry, set range-5~5° C.

5: Bring back the stuff, the electricity cut went on.

Electrical characteristics:
1: Working voltage 5~30v. Notes, use voltmeter functions, at least 7v input voltage
2: Voltmeter Range 7~35v, error 0.01. Voltage is the input voltage
3: Temperature display range-30° c~120° C


Method of use:

- Adjustment time and temperature error correction

Normal Use, press the left button and start flashing, press the right button to increase the number of points, and between 59~0 rings. Fix the points, press the left button, and start to flash, press the right button to increase the number of times, and between 23~0 rings. After adjustment, press the left button to display the mishap.: The mishap is the temperature to be corrected, the unit is the degree. Adjustment of temperature error by right key, range from -5° c~5° C, the positive is the increase, the negative is reduced. Temperature error adjusted, press the left button and save all the data, and return to normal display status.

(Note: Long working hours with netizen response, high temperature measured, that's because of the steady pressure on the boards., and the board is smaller, the heat goes to the temperature resistor, this makes the measured temperature overheated, the solution is to connect the temperature resistance with a line, let it go away from the panel and solve it)

- Switch display mode

In non adjusted state, press the right key to switch display mode, temperature from 1 shows only Time 2 show only T 3 show voltage 4 time Time voltages alternate display between ring switches. And save the last pattern, even if the electricity is cut off and then the machine starts.
