Product Description
Aiming at the highest technology at home and abroad, it adopts large-scale integrated circuits and single-chip microcomputer technology. This instrument is multifunctional, can be used as a tachometer, and can also be used for vibration testing, especially with all functions for measuring dynamic balancing. The instrument is simple to operate, with human-machine dialogue, menu prompts, and measurement data can be locked and held at any time. It is equipped with both internal battery and mains power supply, making it very convenient for on-site dynamic balancing testing of rotating machinery. It can also be used with a balancing machine, directly replacing the balancing machine's electrical box for the renovation of old balancing machines.

Main Functions
● Portable field dynamic balancing instrument is multifunctional, can be used as a tachometer, and can also be used for vibration measurement, especially with all functions for dynamic balancing measurement. (Real-time display of unbalance vibration and phase)
● It has the function of automatically measuring the influence coefficient using the trial weight method and calculating single-plane and double-plane *counterweights, or directly calculating *counterweights based on the measured original vibration when the influence coefficient is known. It can calculate while measuring, or input all at once for calculation.
● It has the ability to calculate the calculated *counterweight to the left and right selected angles.
● It has the frequency analysis capability to detect vibration components at the same frequency, half frequency, and multiple frequency as the rotor.
● Simple operation, the instrument automatically prompts, and general personnel can use it.
Operating Precautions:
1. During continuous measurement, do not press the "Reset" key easily, otherwise all data will be lost. If you have the influence coefficient at hand, you can re-enter it.
2. Be sure to make the photoelectric mark carefully and observe the accuracy of the machine speed. This is an important guarantee for the instrument to carry out dynamic balancing testing.
3. There are many reasons for large machine vibration. Only when the same-frequency amplitude accounts for a large proportion of the total amplitude can the dynamic balancing method reduce vibration. Otherwise, ideal results cannot be achieved.
4. In the dynamic balancing trial weight method, it is necessary to add the known trial weight to the known position of the measured surface. Pay attention to the changes in vibration amplitude and phase after adding the weight compared to the original vibration amplitude and phase. If the data changes are not obvious, the vibration reduction effect after calculation and processing will not be obvious either. If the amplitude change is not obvious, increase the trial weight. If the phase change is not obvious, move the trial weight position again.
5. For the first time balancing a rotor, the trial weight method must be used. After obtaining the influence coefficient through the trial weight method, the influence coefficient method can be used for balancing the same type of rotor, which is simpler to operate.
6. This instrument can be powered by AC 220V or by the internal 12V battery. Generally, it is recommended to charge with AC 220V and power with the 12V battery, so the internal noise is relatively smaller. Please note that when the battery voltage is lower than 10V, it should be charged in time. Otherwise, the battery life will be affected.
7. The magnetic base of the sensor has strong suction and can easily pinch fingers, so please be very careful.
