The intensity of the backlight can be changed using the "backlight” menu.
Note:
Backlight intensity: it should be as bright as required. A backlight that is too bright
reduces the useful life of the display.
6.3 Flow graph bar display
The flow through the measuring cell should be set between 40 and 120 l / h. The flow rate is
limited to 120 l / h in the measuring cell. S200 WCS measures the flow and compensate for the
fluctuations.
Users should set the flow so that the indicator bar is in the middle.
There’s an indication of flow on the screen by small black block, the flow should be between 40-
120L/h (3-5 black block).
So we need to adjust the flow in order to keep 3-5 black block shown on the screen.
If the flow indicator in the display of the S200 is in the middle, then approx. 60 l / h of water will
flow through the measuring cell.
If this is too much for user, then he can return the sample water with the circulation pump.
This is what many customers do when, for example, we measure in hot water.
If we generally reduce the flow, then we have too long a dead time when using a long sample
water pipe.
