5.3.6 Sensitivity standard setting
Command Format: ID + T + x
^
For example, if ID = 14, and value of the turbidity standard = 100 NTU, type 14T100
^
or 00T100
^
In order to verify if the inserted value has been accepted, digit the command H.
5.3.7 Zero calibration
Command Format: ID + Z
^
For example, if ID = 14, type 14Z
^
or 00Z
^
The zero calibration must be done possibly before the sensitivity calibration and in a zero
standard solution.
The standard solution value has to be inserted by following the procedure. For further
information refer to
Zero standard setting
on page 35.
The zero calibration is automatically performed in all the scales starting from the lower scale.
In order to verify the zero calibration, send the command ID + A, the reading must be close to
Zero standard solution value.
Send the command ID + H to control the line
“
Zero calibration: ok /error
”
If the calibration is not
performed (error), the probe will maintain the previous zero value.
Verify if the standard solution and check the surface of the lens and eventually clean by using
soft tissue / cloth.
The message
“
Zero calibration: not done
”
means that the parameter is turned to the default
value by means of the command ID + ZR
5.3.8 Zero Reset
Command Format: ID + ZR
^
For example, if ID = 14, type 14Z
^
or 00Z
^
This command sets zero as default.
Verify the result by means of the command ID + H and check the line
“
Zero calibration: not done
”
