2. Safety Notices

2.1 Warnings and Caution Notices

Warning

!

WARNING: NOT EXPLOSION PROOF!  

Installation of this instrument in an area requiring devices rated as 

intrinsically safe is not recommended.

!

Caution

CAUTION: Some ranges require clean, non-corrosive pressure 

media. See “Media Compatibility” in Section 4, Specifications. This 

instrument is not designed for oxygen use.

!

Caution

CAUTION: Avoid excessive overpressure to the sensor! Externally 

mounted relief valves to provide overpressure protection are avail-

able from Mensor as optional devices, and are highly recommended 

for very low pressure sensors (less than 10 psi).

!

Caution

CAUTION: It is recommended that a backup wrench be used when 

installing fittings or connections on the CPG2300.

!

Caution

CAUTION: Use of a power supply other than the one provided by 

Mensor will invalidate the warranty.

CAUTION: ESD PROTECTION REQUIRED. 

The proper use of grounded work surfaces and personal wrist 

straps are required when coming into contact with exposed circuits 

(printed circuit boards) to prevent static discharge to sensitive 

electronic components.
