Omega Vehicle Security HHP-2000 Series MAX/MIN Recorder, Hose Fitting, Plus Functions

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.

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 HHP-2000, 2020 and 2080

PLUS FUNCTIONS

Models HHP-2020, 2021, 2022, 2023, 2024, 2025, 2080, 2081, 2082, 2084, 2085

SMOOTHING MODE

Press = key and the instrument continuously averages the last four measurements to give a more stable reading on the display. Press = key again to return to normal measurement.

UNITS OF PRESSURE

Press key to select required units of pressure. Chosen units will be saved when the instrument is switched off.

Please refer to the table on the back page.

The HHP-20x0 0-25mbar instruments cannot show the µbar or mmHg symbols on their displays. When switching the units on they are reading in µbar and so show no unit symbol. Pushing the autorange button will put the unit into mbar and show the mbar symbol. When reading in mmHg only the symbol Hg will show on the display.

This function will not operate while in store mode. Note: HHP-2024 - 2084

K = x 103 when using in H2O and Pa. M = x 106 when using in H2O and Pa.
