Q1: Is laser distance meter accurate?
A1: The laser measure is accurate to within 1/8" and measures to 50 feet. It makes this measuring tool more accurate, easier and faster than a tape measure.
Q2: How do I choose a laser distance meter?
A2: Most lasers measurers are easy to fit into the palm of your hand, but some are bigger than others. If you have small hands and want a small unit that is easily controlled, or if you have big hands and need a larger laser for ease of use, check on the exact size of any model you are considering.
Q3: Do laser distance meter work outside?
A3: If you work outside, an optical scope or digital point finder is a must. Without a scope or a point finder, you can see a laser point at a maximum distance of about 30 feet on a bright day. Chances are, if you are measuring outside, 30 feet isn't going to cut it.
Tips: How to use coating thickness gauge correctly?
In the process of use, many novices do not know how to deal with the use of the digital coating thickness gauge due to improper operation.
- The digital coating thickness gauge cannot be turned on. First, check whether the battery is charged and whether the battery is in good contact. Check whether the electrode pads have been oxidized or rusted. You can replace the battery or scrape the oxide layer. If you still can't solve it, look at the button and finally look at the host line failure.
- The digital coating thickness gauge measurement is not accurate. In general, the error range follows ≦ 3% (thickness value) ± 2um. The instrument can be calibrated first and then tested after calibration. Check whether the front end of the probe is intact and place it in a horizontal position on a smooth surface. Note that the probe is perpendicular to the sample. You can also make multiple measurements to reduce accidental errors.
- There is no change in the measurement data of the digital coating thickness gauge. If there is no change in the results measured by the digital coating thickness gauge, you can check whether the probe is damaged, and check the relevant host circuit. If the problem is the data loss caused by abnormal power failure, you can try system calibration.
- The digital coating thickness gauge is turned on but no data is displayed. In this case, there is a backlight and a beeping sound. You can check whether the LCD module is broken, whether the LCD cable is broken due to the external force of the instrument, or whether the related main circuit is faulty. If the thickness of the instrument is immersed in water or oil, you can send the instrument back to the manufacturer for maintenance.
