How to use the safety mark

Instruction for use
- The glycerin pressure gauge should be mounted vertically; otherwise an indication error or leakage of glycerin liquid may occur.
- We do not offer glycerin pressure gauge with a special hand-written graduation.
- All the safety marks are set to zero positions at shipment.
- The transparent sheet at the front is made of polycarbonate (PC). Avoid direct contact of the sheet with any organic solvent. When painting, cover with a polyethylene bag.
- Before use, remove the tip of the safety cap of the glycerin pressure gauge up to the 1MPa indication.
As there is little torque of the Bourdon tube in pressure gauges of less than 1MPa, When the torque of the Bourdon tube in the pressure gauge up to the 1MPa indication is small, the temperature change (internal pressure change) in the gauge case will affect the indication accuracy. By removing the tip of the safety cap, a balance between the internal pressure and atmospheric pressure can be maintained, thereby preserving accuracy. After removing the safety cap tip, make sure that the safety cap faces upwards to prevent leakage of glycerin liquid.
