Gauge difference
The adjustment of the individual measure-
ment loops TAG1 and TAG3 is the same as
the adjustment of single measurement loops,
see "7.1 Adjustment with medium“ and "7.2
Adjustment without medium“. It is also possi-
ble to carry out the adjustment only for meas-
urement loop TAG3. If you want to adjust all
three measurement loops, the sequence is
not important.
Adjustment of the gauge difference
measurement loop (TAG3)
Suspend the sensors to the same level. Note
that a difference of 30 cm (e.g. with weir
control) can correspond to 100 %.
Adjustment with medium
• Make sure the gauge is the same (differ-
ence = 0 %).
• Enter in the menu item "Min-adjust at %“ the
figure "0.0“ (push the "+“ or "-“ key until the
figure "0.0“ flashes, then push the "OK“
key).
• Mark the position of the sensor in the
downstream water.
• Suspend the sensor 30 cm higher (if 30 cm
should correspond to 100 %). A 30 cm
lower gauge is now simulated.
• Enter in the menu item "Max-adjust at %“
the figure "100.0“ (push the "+“ or "-“ key
until the figure "100.0“ flashes, then push
the "OK“ key).
• Suspend the sensor in the original position.
Note:
You can also suspend the sensor in up-
stream water in a lower position to carry out
the max. adjustment.
Adjustment without medium
The easiest way would be to carry out the
adjustment without medium in the adjustment
unit "m“.
