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 HHP-2000, 2001, 2002, 2003, 2020, 2021, 2022, 2023 Ensure both ports are open to atmosphere. If indicated pressure is within 1%f.s (3% for Models HHP-2000, 2020 and 2080) of the factory calibrated zero, press 0.0 key which will adjust the reading to zero.

Models HHP-2080, 2081, 2082, 2083, 2084

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 HHP-2005, 2025

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 HHP-2085
