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.
