Instruction manual. 1. Requires 2xAA batteries (please see ; 744-2199 744-2199 ). 2. Particular care should be taken not to over pressure this device as this may rupture the sensor membrane. This is not covered by the manufacturers warranty. 3. The differential / gauge instruments will only measure positive pressures i.e. positive pressure applied to the positive port, or negative pressure applied to the negative port. 4. Not suitable for use with corrosive substances or cyclic hydrocarbons, e.g. motor oil, transmission fluid and freon. To use these instruments with these fluid components, isolation must be provided in the form of a buffer, such as mineral oil or dry air. 2. Digitron 2023P, 0-7 bar, Differential Manometer. The Digitron 2023P handheld differential manometer takes pressure measurements over a wide range of pressures. It is of robust design, to IP67 with hose connected, and operates between -10 and +50 °C. Features include a backlit display, reinforced silicone keypad and separate battery compartment. The 2023P filters low-level fluctuations to provide a stable display when measuring unsteady pressure levels.
