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
disabled. Also a new password can be entered and saved.
