Specifications Functions and use The testo 510 is a differential pressure measuring instrument. It is normally used to measure small differences in pressure (e.g. to check filter permeability), gas flow pressure measurement, fine draught measurement as well as flow velocity measurement with a Pitot tube.

Product description At a glance 1 Protection cap: Park position 2 Differential pressure sensor nipple connection 3 Display 4 Control keys 5 Battery compartment, holding magnets (on rear) First steps - Inserting batteries: 1 To open the battery compartment, push the battery cover down. 2 Insert batteries (2x 1.5 V type AAA). Observe the polarity! 3 To close the battery compartment, push the battery cover back on. - Basic settings (configuration mode): Adjustable functions

• Unit of pressure/velocity: hPa, mbar, Pa, mmH2O, mmHg, psi, inH2O, inHG, m/s, fpm

• Only if a unit of velocity is selected: Density of the medium (Density): Adjust flashing numbers with , change to the next number with .

• Auto off function: OFF, ON (instrument switches off automatically if no key is pressed for 10 minutes) 1 When switching the instrument on, press and hold until and appear on the display (configuration mode). - The adjustable function is displayed. The current setting flashes. 2 Press ( ) several times until the desired setting flashes. 3 Press ( ) to confirm the input. 4 Repeat steps 2 and 3 for all functions. - The instrument changes to measuring mode.Using the product

Using the product For velocity to be measured, the unit of density and density value must be set correctly, see chapter ‚First steps‘, section ‚Basic settings (configuration mode)‘. - 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. - Zeroing the measuring instrument: The measurement values can be falsified by a change in the position of the measuring instrument. After zeroing, the position of the measuring instrument must not be changed. Carry out zeroing before every measurement in order to compensate faulty positioning or long-term zero- point drift. Zeroing is only possible in a range of 0...10% of the measuring range. The instrument can only be zeroed in the range up to 10 hPa. > Press . - Zeroing takes place. - Changing the display view: Adjustable views

• Hold: Readings are held.

• Max: Maximum values since the instrument was last switched on or last reset.

• Min: Minimum values since the instrument was last switched on or last reset.

• Hold Avg: Timed mean value calculation, see below. > Press several times until the desired view appears.

- Timed mean value calculation for flow: Function only available when unit m/s or fpm is set. 1 Press several times, until Hold and Avg appear in the display. The last result of mean value calculation is displayed. - If mean value calculation was carried out since the last time the instrument was switched on, the last result is displayed. 2 Hold down until - - - - flashes. Releasing starts mean value calculation automatically, the current readings are displayed. 3 End measurement: press . The mean value is displayed. > For further mean value calculation: hold down . 4 End mean value calculation: press briefly. - Resetting Max/Min values: 1 Press several times until the desired view appears. 2 Press and hold until - - - - appears. 3 Repeat steps 1 and 2 for all values that are to be reset. - Switching the instrument off: > Press and hold until the display goes out. Maintaining the product - Changing batteries: 1 To open the battery compartment, push the battery cover down. 2 Remove used batteries and insert new batteries (2x 1.5 V type AAA). Observe the polarity! 3 To close the battery compartment, push the battery cover back on. - Cleaning the housing: > Clean the housing with a moist cloth (soap suds) if it is dirty. Do not use aggressive cleaning agents or solvents!Tips and assistance
