Watson-Marlow 720DuN User Manual 42
18.3 Display
The pump can display three default screens in manual mode: revolutions per
minute, flow rate in a choice of units, or both.
In the first screen of the Setup menu select Display using the UP and DOWN
keys. Press ENTER to confirm your choice.
The pump displays a screen allowing you to choose the format of the manual
mode main screen. Use the UP and DOWN keys to choose and press ENTER
to confirm your decision.
If you choose Flow rate and you have not calibrated the pump since switching
it on, a warning screen is displayed for 4 seconds. The warning does not appear
if the display screen formats are cycled again, unless the pump has been
switched off in the mean time.
The pump redisplays the first screen of the Setup menu.
When the pump next runs, the manual mode main screen will display pump
activity in rpm, flow rate (in the units you chose - see 18.8 Flow units) or both,
according to your choice, plus a cumulative volume figure and a run time fig-
ure. Examples are shown here.
Alternatively ...
In the manual mode main screen, repeatedly press ENTER to cycle the display
between rpm, flow rate (in the units you chose - see 18.8 Flow units) or com-
bined, according to your choice. This cycle operates if the pump is running and
if it is stopped. While the pump is running, you can cycle the display in the
same way by repeatedly pressing START. In both cases, if you have not cali-
brated the pump since switching it on, a warning screen is displayed for 4 sec-
onds before the flow rate screen appears. The warning does not appear if the
display screen formats are cycled again, unless the pump has been switched
off.
The pump redisplays the first screen of the Setup menu.
