7) If the indication instrument makes a big error, remove it from the product for inspection.
It may have been caused by wear, corrosion, external shock, vibration, or shock of a part.
In this case, you must remove, adjust, or exchange the part.
8) The standard rated current shall follow 4. 7) but it may be different when the product is
equipped with a special micro software. Please, add some allowance to the rated current
written in this product, considering the inrush current.
9) The micro switch contact resistance is destined to increase gradually as per the elapsed time.
Under minute load in Si environment, in particular, SiO2 which is accompanied by contact
operation may deposit on the contact to increase the contact resistance abruptly, so you
must ventilate or move to a clean environment. When you use the product for control
sequence input, there is more possibility of contact disorder, so please use an AC 110/220V
buffer relay between the contact and the sequence.
10) Before you open or close the cover for pressure gauge repair or inspection, be sure to shut
off the power.
Malfunctioning of the switch may ignite the explosive gas in the gauge.
10. Use
1) When installing a gauge for the first time, it is recommended to use the valve so it can be
removed or controlled easlily.
2) It is required to find out followings before using the gauge.
- Pulsation exist? If yes, then use Dampner.
- Vibration exist? If yes, then filled the gauge with oil or use oil filled gauge.
- Is ambient temperature high? If yes, then use capillary type gauge.
3) Before using the gauge, make sure zero point is properly adjusted.
4) On the connection screw, use teflon tape or gasket to install the gauge firmly.
5) When installation is finished, slowly open the valve to find out the pointer is correctly
indicating current pressure.
