3. Button and Operation
CLR: Clearance
SM : Store the data
ON/OFF: Switch
Rm: Extra the data
M/ft: Conversion between metric and foot
Data display panel
Power supply
The stored data
The displayed data
Metric
Foot
1. ON/OFF : Switch.
2. m/ft: it means the conversion between metric and foot. If you select (m), the displayed data is based on metric. If you select (ft) ,the displayed data is based on foot.
3. SM: Store the data. You could save the data that shows on the display panel by pressing this button. It could store 5 records that respectively show on M1, M2,M3, M4, M5.( Refer to Table 1)
Before storing After storing Full of the memory
(Table 1)
4. RM: Extract the stored data from SM. For example, if you have already stored the measuring data 5M as M1, 10M as M2. But now the measuring data is 120.7M, you could press the bottom RM once then the digital display panel will shows the the data of M1. The top right of the display panel shows [R". The data of the digital display panel will return to the present data after two seconds. ( Refer to Table 2). If you press the RM twice, the data of the M2 will show on the display panel, the [R" also is on the top right. The data of the digital display panel will return to the present data again after two seconds.
Present data Press the RM Once After 2 seconds
(Table 2)
Present data Press the RM twice After 2 seconds
(Table 3)
5. CLR: Clearance. Once you press this button, the present data will be deleted.
4.Precautions for use
Please open the handle lock to adjust the suitable height of this instrument at first and then close it before using the instrument. Put away the kickstand and turn on the power. Put the wheel on the road to be measured when the data is 0.0m on the digital display panel. Please press the bottom CLR if you want to delete the present data.
1. Please go straight if you want to measure a straight line to ensure the accuracy of the measurement.
2. Do not measure uneven surfaces because it will reduce the accuracy.
3. Do not measure in the rain for a long time.
4. Do not use the instrument under the high temperature environment or keep this product in the high temperature place.
5. Please open the battery cover by using the cross-head screwdriver and change the battery when the digital display panel is dark.
6. Do not deal with the used batteries by yourself, please send them to the government designated place where to recycle them.
7. Please remove the battery and clean the instrument by use the mild detergent to prevent rust if you haven`t used it for a long time. Then please pack it well and save it in the rough place.
8. Do not use benzene solution to clean the instrument, otherwise its surface will be corroded.
9. Do not use this the instrument as a toy for child for avoiding unnecessary damage.

Hidden Trouble in the Market: Material is not uniform, and there are differences in the process. The appearance of aluminum alloy doors and windows is bright and durable. However, as the market share of demand continues to saturate, the competition between the aluminum alloy processing industry is becoming increasingly apparent. In order to reduce costs and achieve greater market share, some processing manufacturers have made inroads in materials and arbitrarily used low-quality materials for combination processing, which eventually led to the uneven quality of aluminum alloy doors and windows.
The market for steel doors and windows is rather confusing, and the same profiles have different prices due to different parts and processing technologies. In the regular market, the double-glazed casement windows are generally about 400 yuan per square meter, and most of the insulating glass windows are more than 1,000 yuan per square meter. The defects of some poor-quality plastic steel doors and windows are obvious: auxiliary materials such as beads and seals are not matched with the main sections, and they have rough appearance and poor sealing performance. The steel bracing thickness of inferior steel doors and windows is not up to standard, even without steel bracing, so that its service life will be greatly shortened.
Plastic-steel windows have gradually become the trend of life for high-end doors and windows. Currently, plastic-steel windows are the most commonly used products. However, plastic windows have generally low sand-resistance performance and water-tightness, and their window frames have a large light-shielding area and a high coefficient of thermal expansion. Therefore, there is a problem of photo-thermal aging. Wooden windows can be used for viewing, ventilation, diversion, lighting, heat insulation, sound insulation, heat preservation, and coordination of interior furnishings. It is a banner to create an indoor environment and is gradually becoming a lifestyle trend for high-end windows and doors.
Ya Zhi Xuan, said that the doors and windows, aluminum alloy doors and windows are in the direction of high-grade energy-saving, sound insulation; traditional solid belly, fasting steel doors and windows due to its poor overall performance and is gradually being eliminated, and people have gradually developed a variety of meet different The need for color doors and windows, stainless steel doors and windows, and energy-saving color plate doors and windows with heat insulation; the use of high-grade wooden doors and windows, aluminum-clad wooden doors and windows will increase.
Consumers have higher demands on the functions of doors and windows. In terms of function, consumers have put forward higher requirements for the functions of heat insulation and UV protection of doors and windows. According to the statistics of Chiba furniture, the energy consumption of doors and windows accounts for more than 70 percent of the energy consumption of buildings, while the energy consumption of doors and windows is mainly generated by conduction, radiation, and convection. They are based on the aspects of frame materials, glass, and machining accuracy. Take consideration.
