High temperature heat insulation electronic crane scale maintenance measures
 In the use of high temperature heat insulation electronic crane scale, the necessary maintenance measures can effectively extend its service life, to ensure the smooth progress of our work, how to do a scientific and reasonable high temperature heat insulation electronic crane scale maintenance work?
 High temperature insulation electronic crane scale maintenance:
 (1)  crane scale battery power supply, in the use of the process should avoid using too low voltage, otherwise the battery life will be shortened. Please do your best in principle. If the scale body stops working for more than two hours, please remove the battery of the scale body. If the meter stops working for  more than one week, turn off the power switch of the meter. Storage do not use, more than a month to ensure that the scale body battery and meter battery once a month to charge.
 (2)  to extend the battery life, it is better to turn off the instrument backlight during the day.
 (3)  it is forbidden to use strong solvent (such as benzene, nitrogen-based oil) to clean crane scales. When be like clean, can use the soft cloth dot that does not rise to touch water to touch again some neutral scour (soap) undertake cleanness. After cleaning, please wipe the crane scale with a soft cloth that does not raise hair. To prevent the corrosion and damage of crane scales to ensure safety.
 Correct use method of high temperature heat insulation electronic crane scale.
 Before the use of electronic crane scale, should be the corresponding battery into the scale body and handheld device to install or replace the battery, need to tighten the battery clamp lock screw, check whether the battery clamp is firmly fixed on the scale body, and then close the door of the crane scale to prevent accidents.
 When the meter shows low voltage, the battery pack should be replaced immediately and the replaced battery should be charged in time to prevent battery damage. When the battery pack is not in use for a long time, it should be recharged at regular intervals. The battery should be stored in a dry and ventilated environment with appropriate temperature, and avoid contact with corrosive substances. When loading and unloading battery pack connector socket, do not use the hand to grasp the clamp wire cap clamping wire, and should grasp the base, the other side of the transmitter power connection on the plug do not  grasp the clamp wire cap, should grasp the head of the rotating cap for loading and unloading, to prevent the power connection loose, causing trouble. Before the transmitter is connected to the power supply, the antenna and its feeder must be connected reliably, otherwise the transmitter will be damaged.
 Electronic crane scale in daily use is not to avoid problems, so how do we solve the problem?
 1.  No return to zero.
 A.  Check whether the output signal value of sensor is within the standard.
 B.  If it is not in the standard, please refer to item 10 for compensation.
 C.  If it cannot be compensated, please check whether the sensor is defective.
 D.  Please correct the weight according to the instruction manual.
 2,  weight is not correct
 A.  Observe whether the internal code value is stable, whether there is friction at various parts of the sensor, whether the voltage regulator is stable, whether the operational amplifier circuit is normal, whether there is any foreign  matter in the circuit version of a /D circuit, and whether the feedback resistance/capacitor/filter capacitor is defective or leakage.
 B.  Check whether the output signal value of sensor is within the standard.
 C.  If it is not in the standard, please refer to item 10 for compensation.
 D.  Use weights to test whether the scale is even.
 E.  Please correct the weight according to the instruction manual.
