cal ib ration. The range of automa tic cal ib ra tion i s
recommended to be the most commonly used range. At the
same time, the range that is not used very often is the regular
and manual calibration. The increased measurement error
caused by the changes to environmental conditions and other
conditions can be avoided through calibration.
Verification (Manual or Auto-
validation) settings
Verification is also referred to as standard sample verification,
which uses a standard solution of known concentration to
verify the accuracy of the instrument after last calibration.
Standard solutions with known concentrations are generally
used for verification. Verification can be performed manually
or automatically at a set interval. The verification settings
include enable, first start time, interval, standard sample
concentration, allowable deviation range, and automatic
verification interval. To set verification settings, go to manual
operation
verification on touch screen.
When the automatic verification is set to on, the instrument
will automatically run verification according to the set interval
to check the accuracy of the analyzer.
The automatic verification start time refers to the time when
the automatic verification is turned on for the first time. The
setting of this time will affect the validity of the data (the
number of data measured in cycles). In the actual setting, it is
recommended that the cycle start time +30 min, which is
30 minutes later than the cycle measurement.
The interval (verification period) refers to the interval of
automatic verification. In the application of waste sample, it is
recommended to set it to 24h.
Standard solution concentration: The standard solution
concentration is the concentration of the standard solution
that is used for automatically verification. The difference
between the automatic verification result and the standard
concentration is the automatic verification variance.
The allowable deviation refers to the maximum allowable
variance of the result of automatic standard verification. When
automatic verification is turned on, the verification result
exceeds the allowable deviation, and the standard sample
verification exception handling mechanism (automatic
calibration, etc.) is automatically activated.
When the measured variance exceeds the allowable
deviation, the instrument will conduct an auto-calibration and
rerun the validation test to ensure the instrument is accurate
enough for the measurement.
Remarks:
The concentration of standard sample verification
is calculated as Ammonia in the form of Nitrogen.
Deep Cleaning Setting
Special deep cleaning solution is must be used for deep
cleaning. When setting up this interface, ensure the relevant
settings are within a reasonable range, otherwise it will cause
abnormal data or even unnecessary hazards, therefore, you
must be careful.
Deep cleaning is used to deal with the abnormal data caused
by material adhesion in the tube, reaction cell and measuring
cell. It is not a necessary process, and this function is only
needed when necessary.
The Deep Cleaning Setting mainly sets up whether to perform
the deep cleaning or not and the interval of automatic deep
cleaning. When the automatic deep cleaning is enabled, the
interval of deep cleaning can be set.
Input/Output Setting
This interface is used to set up the relay, digital input, analog
output, RS485, etc.
Relay Setting:
It is used to set up relays (including 2 relays)
and pre/post-running. Relay is mainly used for external
output, and pre/post-running is used for control of other
peripheral equipment. The relays and pre/post-running are
mutually exclusive.
Relay setting includes the Off setting and operating mode
setting (alarms and events).
The working mode includes
the alarms and events, in which, the working mode and
Off are mutually exclusive.
Alarms will occur in the following three cases:
exceeding
the upper limit or the lower limit. In the on-line environmental
detection of ammonia nitrogen at discharge ports, exceeding
the upper limit is most commonly used. For example, the
environmental protection requirement of a discharge port is
4.5 mg/L, generally, it is required to raise an alarm when
exceeding 4.5 mg/L, which can be realized by exceeding the
upper limit. If the upper limit range for the upper/lower limit is
set to 4.5 mg/L, then an alarm will be output when the
concentration exceeds 4.5 mg/L. If the measured value lower
