This is not covered by the manufacturers warranty. NOTE: 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. INSTRUMENT APPLICATION The range of 2000P instruments are suitable for gauge, differential, or absolute measurements over a wide range of pressures. They are not suitable for use with corrosive substances or cyclic hydrocarbons, e.g. motor oil, transmission fluid and freon. To use the 2000P with these components, isolation must be provided in the form of a buffer, such as a mineral oil or dry air. INSTRUMENT OPERATION BATTERIES Two AA or equivalent cells (not supplied). Follow instructions on reverse of instrument for fitting/replacement. When symbol appears on display, replace batteries. IP65/IP67 RATING The waterproof rating for this product will not be maintained unless the screws holding the battery compartment are firmly tightened when inserting or replacing batteries. ON -OFF Press ON key for on and OFF key for off. Automatic switch-off after 12 minutes, unless any key is activated or the instrument is in LOG or MAX/MIN mode. If key is held when unit is switched on, automatic switch-off function will be disabled until the unit is switched off. BACKLIGHT Press and hold ON key. DISPLAY MULTIFUNCTION AVERAGE CAL MULTIFUNCTION TIME LOG NUMERIC HH:MM ENTRY NE A/R Cal P 321 OK? mbar PSI BATTERY YES PSI in HO mm 2 inHg kPa MULTIFUNCTION cm M OUT OF RANGE If pressure exceeds the scale range Out will appear on the display. ZEROING In order to achieve maximum accuracy it is recommended to zero the instrument in the orientation it will be used before taking any measurements. Models 2000P, 2001P, 2002P, 2003P, 2020P, 2021P, 2022P, 2023P Ensure both ports are open to atmosphere. If indicated pressure is within 1%f.s (3% for Models 2000P, 2020P and 2080P) of the factory calibrated zero, press 0.0 key which will adjust the reading to zero. Models 2080P, 2081P, 2082P, 2083P, 2084P As above but press key instead of the 0.0 key. ZEROING ABSOLUTE This feature enables correction of the indicated ambient pressure between 900mbar and 1100mbar. Models 2005P, 2025P Open port to atmosphere and the instrument will indicate ambient pressure. Press 0.0 key and 900mbar (or the equivalent in other engineering units) will appear on the display. Press and hold this key. The display will scroll and when required atmospheric pressure is displayed (maximum 1100mbar) release key. The current pressure being measured will then be adjusted to the displayed reading and used for the rest of the session. Note: This setting will be lost when the instrument is switched off. Model 2085P Press key instead of 0.0 key. DISPLAY HOLD Pressing key freezes the display. The symbol will appear on the display. Press key again to return to normal display. HOSE FITTING The input port(s) on the instrument are designed to accept a hose with 4mm I.D. and 1mm wall. The hose is fitted by unscrewing the clamping nut, sliding the hose on to the stepped shaft and refitting the nut. ENTER RANGE Note: Do not tighten fittings attached to the pressure ports to a torque greater than 2Nm otherwise the pressure seals may be damaged. HAND PUMP OPERATION (if applicable) Use the T piece to connect the hand pump to the instrument’s + port and to the equipment being tested. Exhaust the system by turning the release valve on the hand pump anti-clockwise and set the fine adjustment threaded piston to mid range. Close the release valve and apply pump action to the hand pump piston to generate the required approximate pressure. Fine adjustment of the desired pressure can then be made by rotating the threaded piston. The release valve may be used to vent the system. Note: The hand pump is capable of generating 7bar max. It is, therefore, essential that extra care is taken not to over-pressure the instrument. A pump must not be used on models 2000P, 202...
