User Warnings; Water Temperature - Wasserlab Micromatic DA Manual Del Usuario

8.2 User warnings

The Micromatic equipment carries out constant monitoring of
various operating parameters and alerts the user via acoustic
signals and activation of the corresponding icon:
• Pretreatment changes: When the equipment exceeds the
number of operating hours assigned to the pretreatment
this warning is activated, indicating that the cartridges must
be changed [1] and [2].
• Deionisation resin change: This warning is activated
when the equipment detects that the Type II Water
conductivity is higher than the set value. By default, a
maximum of 10 µS/cm is set.
different value (between 1 and 20 µS/cm).
• Water cut off: An icon is activated indicating that water
has stopped entering the equipment.
•
Conductivity probe:
Conductivity probe does not measure correctly.
8.3 Entering parameters
(set-up menu)
The system allows the user to set values for:

- Water temperature

- Conductivity for Type II Water
- Pretreatment change
Press MODE/ESC to access the set-up menu.
The screen displays the following values in sequence (by
pressing the keys and )

To modify the set values, take the following steps:
a. Select the parameter (for example Value uS)
b. ENTER = The first digit blinks. To modify it press
until the desired value is shown. To accept, press
ENTER.

d. The third digit blinks. Perform the same operation
and the value will be set.
e. To exit the set-up menu = ESC.
8.3.1 Set value for deionisation resin change
The equipment is delivered with a set value of 10 µS/cm:
When the Type II Water reaches or exceeds the conductivity
value, the warning to change the deionisation resin cartridges
[3] and [4] is activated.
The user can select a different set value (between 1 and 20
µS/cm) to activate this warning.
8.3.2 Water temperature
The conductivity values displayed on the screen are
compensated at 25°C.
The conductivity value depends on the water temperature and
is usually expressed by normalising the reading to 25°C. To
this end, the water temperature at which measurement is
performed must be taken into account and a correction factor
of 2% applied for each degree of temperature deviation from
the reference temperature:
C = Conductivity at 25ºC (µS/cm)
25
C = Conductivity at temperature t (µS/cm)
t
t = temperature at which measurement is performed
(°C)
By default the equipment is delivered with a temperature
value of 25ºC.
8.3.3 Resetting the pretreatment hour meter
When the pretreatment is changed, it is necessary to reset the
hour meter:
1. Access the set-up menu: Press MODE/ESC
▲ ▲
2. Press +
3. The screen displays the equipment operating
hours
4. Press ENTER: The value on the screen blinks
5. Press ENTER: The meter must be reset to
000 hours
6. Press MODE/ESC to exit the set-up menu and
return to main screen
