Product introduction:
Ultrasonic apparatus is completely suitable for a family to decorate， buy air conditioning calculation area of volume， real estate agent or construction workers must， need room and room area is fast measurement tools， ultrasonic apparatus that can measure straight distance from 0.50 M to 18 M. (1.5 feet-60 feet) ultrasonic apparatus is using emit ultrasonic to object to be tested， then the ultrasonic time to determine from the distance is measured.
Ultrasonic apparatus in foreign countries is known as the "electronic tape"， for building， decoration， engineering， etc can do traditional tape measure power measurement. Our sales of ultrasonic apparatus according to manufacturer offers data shows that is already the international performance better products， and in Europe and America market share a quite high compared to other brand of ranger in ultrasonic launching Angle， anti-jamming processing， etc have obvious difference on.

When measuring the note:
1. Ultrasonic meter test is from the distance at bottom of machine obstacles， not from the top， if with the top shall prevail， you will find that the actual distance always have the distance and so a few centimeters of 10 error， ha ha.
2. Measuring time with wall body be vertical as far as possible， especially the distance is farther， the vertical， measurement data accuracy is higher， and the greater the Angle， the greater the error. Long distance measurement Suggestions to open the laser positioning to keep the vertical
Warning: if it is a month or more than one month no， please take out the batteries， lest battery long time without leakage damaged instruments.
The ranger stabilizing treatment:
This instrument is very sensitive to temperature and humidity before using， 15-30 minutes until rangefinder stability to room temperature.
Please according to the following steps to install batteries:
1. The battery compartment according to the direction of the arrow to put;
2. Cover is pushing slides open， battery room have positive and negative (+ and-poles.
3. Open the lid
4. When showing low power or ranger doesn't work， please replace the it.
Ranger switch:
To open this instrument， please press "MEASURER" even in dim light can easily be screens， such as the voltage stability， can see at that time， the environment temperature.
30 seconds if will not automatically shut off.
When measuring the:
1. Please click the "MEASURE"， this instrument will MEASURE the instrument to radar to the other end of the measurement.
2. Make the bottom of the instrument near the wall， ceiling is probably the distance to the floor. Make sure that you do not have between the distance measurement obstacles， your head or your hands in the front of the measurement instrument is not.
3. Repeat press "FEET" or "METER"， "FEET" said to FEET measurement， or appear "METER" said to m measurement.
Explanation:
Measuring instrument display is generally in 30 seconds， if you change another model is also to 30 seconds.
If you measure range of less than two feet (0.5 meters) or is greater than 60 feet (18.288 meters) will show "ERROR"
Measuring the little secret:
Some curtain can absorb sound waves and lead to measuring instrument to measure. If you have the curtain in measuring indoor words， please first the curtain on the other side of the window， and close the window.
If the distance is measured in the obstacles of words， the ultrasonic measure out of the data is not correct， for example， tables， chairs， or other obstacles. If you're not sure you measure of whether correctly， that you from different Angle to DuoCi measurement.
If you measure is not smooth place or is a very narrow corner， then you that the data is wrong.
If you want to measure the distance of more than 60 feet (18.288 meters) that the choice of the middle of the house of a bit， for example: from which point to each side measurement， then add up.
Reduce the measurement error:
1. According to these steps with "measure" to measure a size
2. Click "STORE" button， you can put the measurement data stored in the memory card M1 and M2 or M3 card face.
3. If necessary， just repeat the first and the second step to store data.
4. If you want to store data on which memory card， press the M1 and M2 or M3 card. Such data has it.
5. If you want to store the new data， it would direct the original data deleted.
6. If you want to delete ALL the data of words， then click "ALL MEMORY CLEAR" hold 3 seconds， and then ALL of the data and M1 and M2， such as M3 will temporarily disappeared.
Note: the date and the voice is after deletion can't save
