1. What is the display routine?
The second line in the display is intended to
be used to:
- Show actual status
- Show messages
- Show errors
When delivered from the factory the
EXASC200 shows the temperature on the
second line.
You can make the instrument show a diffe-
rent parameter on the second line by selec-
ting it from the list at right.
2. What can you read?
Temperature is an actual value.
Output is an actual value.
Percent by weight is an actual value.
Cell constant is programmed.
Reference temperature is programmed.
NaCl or temperature coefficient is program-
med.
The choice of temperature units is done
from the Service level.
Error messages have priority over other
messages.
Note: Percent by weight is only visible when
activated from the service level §7-13.
3. Example
To check the value of the output signal
(4...20 mA) it is displayed on the second
line.
Measuring range 0...100 µS/cm
Output signal 4...20 mA
Process value 60 µS/cm
Output value 13.6 mA
When the second line is changed to display
output the current signal is visible all the
time.
Whenever HOLD is activated the value on
the display is frozen to the programmed
value (using the FIXED setting).
Pressing MODE will take you back to
measuring and the temperature will show
again.
