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.

First steps

²Inserting batteries:

1To open the battery compartment, push the battery cover

down.

2Insert batteries (2x 1.5 V type AAA). Observe the polarity!

3To close the battery compartment, push the battery cover

back on.

²Basic settings (configuration mode):

Adjustable functions

· Unit of height above mean sea level: m, ft

· Value of height above mean sea level (Altitude): Set flashing figure with ,

change to next figure with .

· Unit of pressure: hPa, mbar, Pa, mmH2O, mmHg, psi, inH2O, inHG,

· Auto off function: OFF, ON (instrument switches off automatically if no key is

pressed for 10 minutes)

1When switching the instrument on, press and hold until

and appear on the display (configuration mode).

- The adjustable function is displayed. The current setting

flashes.

2Press ( ) several times until the desired setting flashes.

3Press ( ) to confirm the input.

4Repeat steps 2and 3for all functions.

- The instrument changes to measuring mode.

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.

²Switching the instrument on:

iPress .

- Measuring mode is opened.

²Switching the display light on:

The instrument is switched on.

iPress .

- The display light goes out automatically if no key is

pressed for 10 seconds.
