Характеристики


Hand-held digital tachometers are one of the universal mechanical test instruments with wide measuring range, high precision and recording function, which can measure rotational speed and surface speed. Compared with general tachometers, this style tachometers are much easy to operate for its portable exquisite size and ergonomically design. At present, for the smart digital tachometers, we have contact, non-contact, contact + non-contact (photo) 3 main categories. As an aside, for the non-contact (photo) Tach-testing, it needs to attach reflective mark to the rotating object to be measured, and the visible light of the tachometer is aligned with the reflective mark for measurement.

Precautions:


1. As this digital tachometer belongs to hand-held instrument, the measured value may exist inevitable human error due caused by shaking of the operator's arm. Therefore, the operator’s hands should be steady and the force should be appropriate when measuring. It is necessary not only to avoid the top is too loose, resulting in the error of sliding and throwing,  but also to avoid too tight top, damaging the tachometer; ensure there’s no relative sliding between the tachometer shaft and the measured shaft shall prevail. For some special measured objects, it is recommended that users fix the meter when necessary before measuring.


 


2. During the test, the center of the test shaft of the tachometer and the shaft under test should be on the same horizontal line, and the head of the meter should bear the shaft.


 


3. Before using, we can put some lubricating oil (clock oil) the tachometer, can inject from the oil filling hole of the housing and range switch.


 


4. After the instrument is used, it should be wiped clean and placed in a place where it cannot be directly exposed to sunlight, away from heat sources, and pay attention to moisture and corrosion protection.


 


5. If the meter will not be used for a long time, please remove the battery to prevent battery leakage and damage to the meter.
