DT-2235B Generator Engine Tachometer Meter
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.
