Matters needing attention in the use of electronic hook scales
1. Electronic hook scale is strictly prohibited from overloading, loading weight as far as possible uniform and stable, to prevent a great shake.
2. The communication distance of wireless transmission hook scale is restricted by many factors. In the following cases, the communication distance may be affected:
There are obstacles between A. instrument and scale body.
The power supply of B. scale transmitter is short.
There are interference sources or low ambient temperatures near c..
The D. hook scale does not record weight before the object is fully lifted or when the crane is still shaking violently.
E. is strictly prohibited to use the scale as a partial lifting load or cable pulling operation of the steel cable.
F. when the factory needs to increase the hook scale, it should be careful not to purchase the hook scale with the same frequency as before.
G. In hoisting operation, attention should be paid to preventing the frequency drift of transmitter caused by the violent collision between the hoisted articles and the weighing body.
H. pay attention to whether the body of the scale and the antenna on the instrument are loaded and intact.
Two, electronic hook scale battery use matters needing attention
1. Batteries in the scales are only allowed to be charged by randomly equipped chargers. It is forbidden to charge the batteries with other devices.
2. when the ambient temperature is too low, the working time of Ni Cd battery in the scale can not be guaranteed.
3. if it is not used, the battery will gradually discharge itself.
4. In order to achieve the best performance of the battery, it is recommended to charge the battery for at least 12 hours before using new or long-term unused batteries.
5. the new battery needs several charging and discharging processes to achieve the best performance.
6. New batteries or long-term unused batteries may cause the charger to show prematurely that the battery is fully charged. Continue to charge the battery for a few hours when you see the indication that the battery is fully charged.
7. When the battery does not continue to use, please use up the battery, and then put it in a cool, dark, dry place.
8. when using Cranem instrument battery power, try to prevent the use of built-in micro beat.
