Dont put battery anode and cathode reversed. rechargeable battery is available ，better use Nickel hydride batteries .rechargeable power must be standardC and match with our production.2. Insert sensor aligning and

13、 correct. 3. Adjust the end of sensor repeatedly to be vertical to the surface to measured level. The distance between the probe and surface depends on the maximum displacement of the surface to be measured, blind zone of the instrument and range of probe. 4. If the liquid to be measured is sewage o

14、r containing afloat impurities, a wire-fence should be placed under the probe to keep them out of the normal measurement range of the probe. Otherwise correct and stable display can not be obtained.5.Set transmitted pulse intensity properly，avoid abnormal phenomenon.、Connection schema1、 Power and se
