Application Procedure:
Proper treatment of the precision level

- Before use, the water level will be brought to the same temperature as the object to be measured. Both parts must be in the range of working temperature.
- The measurement of the surface area to be measured and the measuring surface of the water level must be absolutely clean.
- The water level must be moved (slide) onto the surface to be measured (not lay down).
- The water level must be on the surface to be measured always pushed to the same place, so that any  
unevennesses in the surface to be measured are excluded.
- On a good contact at the interface between the measurement surface and water balance is essential to check. The water level should always lie full. May shure that there is no damage at the measuring surface (elevation) and must not tilt or wobble in particular.
- The water level before and during the measurement may be handled only by the designated plastic handles (heat protection).
- Human body and breathing heat can affect the measurement result. Unnecessarily long body near the water level should be avoided.
- The measurement results can be read only when the bubble comes to a complete rest. This can vary depending on the sensitivity of up to 40 seconds.
- To eliminate all measurement error is generally a control measurement on envelope (turn 180 degrees) is recommended.

 

Testing of the mechanical level (zero error)

Push the water balance on a clean, flat and level as possible aligned measuring surface: by reversal measurement. Left of the long line (Zeroline) is the -range and right of the long line is the +range. In the first measurement, the transverse level must find the right because otherwise the sign of the result changes (factory setting). The position of aging resting dragonfly is the first measurement value A reading on the scale. The bubble level 180 ° turn and slide it on the same position of the measuring plate. Subtract the second scale value B from A and divide by 2 gives the slope (A - B) / 2. The respective measurement value is also for the envelope, always (as seen by the viewer) at the same right zero mark.Examination of the backing (slope of the measurement area)

Push the water balance on a clean, flat and level as possible aligned measuring surface: by reversal measurement. Left of the long line (Zeroline) is the -range and right of the long line is the +range. The position of aging resting dragonfly is the first
measurement value A reading on the scale. The bubble level 180 ° turn and slide it on the same position of the measuring plate. Add the second scale value B to A and divide by 2 gives the slope (A + B) / 2. The respective measurement value is also for the envelope, always (as seen by the viewer) at the same right zero mark.
