A Brief Introduction to the Adjustment Method of Level Meter Zero Calibration
Put the spirit level on a stable foundation and roughly level plate (or machine guide rail), after the bubble is stable, take a reading at one end such as the left end, and set it to zero. Then turn the level meter 180 degrees, and still put it on the original position of the plate. After the bubble is stabilized, still read the A grid at the original end (left end), then the zero position error of the level meter is 1/2 of the A grid.
If the zero error exceeds the allowable range, adjust the level meter zero adjustment mechanism (adjustment screw or nut to reduce the zero error to within the allowable value. For non-regulated adjustment screws, the nut must not be screwed at will. Before adjustment, the level meter works The surface and the plate must be wiped clean. After adjustment, the screws or nuts must be tightened).
Level FAQ
1 The switch knob is not fully turned.
2 Open the case and check whether the copper wire is desoldered. In general, if there is a horn sound after the battery is installed, but no light is on, this is the case
3 Battery box - Check if the welding wire is broken, and if the spring is in good contact with the battery.
4 Test the switch circuit to see whether the micro switch is powered on or not. If it is powered on, it means that the switch is normal. If it is not powered, please replace the micro switch.
5. The main board of the line, if all the above problems are checked, the main board must be replaced.
6 The horizontal line of the laser tube is not bright: first check to see if the copper wire is broken, and then check whether the lower pair is on or not. If the lower pair is not on, you have to remove the black wire from the last line of the wiring board , the horizontal line is just fine.
