Please read instructions carefully prior to using the instrument for proper and safe operations. 

Mishandling could cause device malfunctions and result in disastrous injuries or accidents. 

1. Do not exceed the pressure range allowed. 
2. Do not use it to measure the pressure of corrosive fluid. 

Damage or rupture of pressure gauge may cause release of fluid which could 
lead to bodily injury or destroy surrounding area. 

3. Do not apply excessive load, vibration or impact. 
4. Please use within the specified temperature ranges. 

Exceeding the temperature range may cause disruption in nearby area due to damage
to the temperature indicator. 

5. Please use this within the rated input and output specification range stipulated in  

the specification, or it may cause equipment trouble.

6. Please use a compression terminal with insulation sheath at the end of wire.
7. Please use a cable gland of the same class or upper class.
8. Please construct wiring in accordance with consumers' electrical installation guide 

and electrical facilities technical standards. 

9. Make sure to turn off the valve to prevent the measuring fluid leak when dismounting

the gauge. 

10. Use a pressure gauge with no oil in an environment with hydrocarbon or oxygen.  

Oil contained in the gauge may react with oxygen which may be flammable or explosive. 

11. Please always follow the mounting instructions in the manual in cases of field installation. 
12. Do not make any modifications to the product or to add more functions. 

Please consult with us for any repair.

13. Please be sure to close a valve and cut off pressure in advance in opening the case

 of this product. 
Please be sure to cut off power because there is a risk of electric shock if wiring 

14. Work is carried out while electricity is applied. 

This product cannot be used in explosion proof area. 
Please use P970, P990( explosion proof type electric contact pressure indicator )
that is the product of our company, if necessary.
