3 Operation

3.1 General

Bronkhorst High‐Tech instruments are designed in such a way that they will meet user process

requirements in the best possible way. Flow meters and controllers are powered from a dc power

sourcewithaminimalripple.Whenprovidingyourownpowersupplybesurethatvoltageandcurrent

ratingare

accordingtothespecificationsoftheinstrumentandfurthermorethatthesourceiscapable

ofdelivering enoughenergytotheinstrument.Cablewirediameters shouldbe sufficient tocarry the

supplycurrentandvoltagelossesmustbekeptaslowaspossible.

3.2 Power and warm-up

Before switching on the power, be sure all connections have been made according to the hook‐up

diagramin2.7.Checkgasconnectionsandmakesurethereisnoleakage.Ifneededpurgethesystem

withapropergas.Turnonpowerandallowatleast30minutesforwarmingup

andstabilizing.During

thewarm‐upperiod,gaspressuremayeitherbeonoroff.



3.3 Setting up the instrument

Afterpoweringon,thefirsttime,theinstrumentwillaskwhichgasisusedandwhichflowrangeistobe

used(seepicturebelow).

Navigatetothefluidnameusingthe4‐waybutton(upanddowndirection)andpressinthecentreto

makeaselection,thenselecttherange

usingtheupanddowndirectionandpressalsointhecentreto

maketheselection.



Afterselectingthefluidandtherange,thecommunicationtypecanbeselected.

Thesettingswillbestoredwhenthe“save”buttonispressed.



Then turn on gas supply gently. Avoid pressure

shocks, and bring the instrument gradually up to the

leveloftheactualoperatingconditions.Alsoswitchoffgassupplygently.



The MASS‐VIEW

  is designed in such a way that for a change in therange or gas, you simplyselect

anotheravailablerangeorgasinthemenu.



Afterenteringthedefaultpassword(whichis‘abc’)inthesecuritymenu,allmenu’scanbeenabledor
