Specifications

Functions and use

The testo 511 is an absolute pressure measuring instrument. It

is normally used to measure absolute pressure, e.g. for pressure

compensation in velocity measurement in ducts, laboratories

and production processes. Further measurement parameters are

barometric (surface) pressure (= pressure at sea level) and altitude

above sea level.

Using the product

For measuring barometric (surface) pressure barom (= pressure

at sea level), the following must be observed:

·the altitude of the measurement site above sea level must

be known, and be set in the instrument, see chapter First

steps, section Basic settings (configuration mode).

· The barometric pressure displayed is only correct for the

altitude set, for a change of altitude, the altitude above sea

level must be reset.

For measuring barometric Altitude (= altitude relating to a fixed

level), the following must be observed:

· The altitude above sea level at the starting point of the

measurement (= Reference altitude) must be known and

be set in the instrument, see chapter First steps, section

Basic settings (configuration mode). When entering the

reference altitude, the current absolute pressure is also

stored as a reference pressure.

· When carrying out the measurement at the destination, the

weather conditions must be the same as when entering the

reference altitude. If the weather has changed (= change of

absolute pressure), a new reference value must be entered.

Switching the instrument on:

> Press .

- Measuring mode is opened.

Switching the display light on:

The instrument is switched on.

> Press .

- The display light goes out automatically if no key is

pressed for 10 seconds.
