5. Use the operation

5.1 Product Initialization

5.1.1 Initialize the device at startup

After the device is powered on, it will perform initialization, device self-test and other actions, and the distribution arm will automatically rotate to the first bottle, and then automatically rotate to the position of the bottle number before the power down.

Figure 5.0 - Initialization

5.1.2 User Login

Figure 5.1 - Login

After the device is initialized, enter the user login page. "Guest" can directly enter the main interface of the device, and can view the device status, data recording information, etc., but cannot set parameters, start and stop the device, and other operations. The "operator" needs to enter the corresponding password to be able to enter the equipment, and the "operator" has all the rights of "guest", and can set basic parameters, can start, stop and reset the distribution arm and other operations. "Administrator" is the internal debug portal.

5.2 Main Interface

The main interface is mainly divided into standby interface, sampling setting interface, and operation interface

The device status bar is below the instrument, which is described as follows:

Running status: equipment flow and action status display;

Timed start icon: The

Refrigerator Door Status: Appears

Failure icon:

Serial communication connection status of the host computer: this "

System Time: Click the system time display area on the parameter setting page to modify the system time.

5.2.1 Standby

The standby interface consists of sampling information, timer start time, refrigerator temperature and related operation buttons.

Figure 5.2 - Running Standby

Sampling Information: The sampling information corresponding to the device during sampling.

Sample retention information: The equipment corresponds to the sample retention information when the sample is retained.

The timed start time, which is only valid when the device status is standby and the timed start icon in the status bar is valid.

Drug Remaining: The current amount of curing agent remaining.

Refrigerator temperature: The real-time temperature inside the refrigerator.

The information such as the number of mixed samples, the number of samples, the interval time, and the cumulative flow rate are the status information in the sampling modes such as "fixed flow quantitative", "timing ratio", and "timing quantitative".

When the user is an "operator" or "administrator", actions such as "stop" and "bottle reset" can be effectively performed.

Stop: Select the "Stop" button when the device is running, and the instrument will stop the subsequent action and return to the standby state after the current action is completed.

Bottle reset: Select the "Bottle Reset" button in the standby state and the device door is open, the machine will empty the information of the sample bottle, and the turntable will rotate to the starting position.

Sample supply: Select the "Sample Supply" button in the standby state, and the instrument will enter the sample supply process.

"Switch to Sample Settings": You can switch to the sampling mode/sample retention mode setting interface.

5.2.2 Sampling mode - constant flow quantification 

Figure 5.3 - Sampling Mode - Constant Flow Quantitation

Constant flow quantitative sampling mode: When the cumulative flow rate of the external flowmeter reaches the set cumulative flow, the device starts to retain the sample, the sample volume is ml, the sampling times is 1 time, and the cumulative flow rate is reset to zero, and the previous action is repeated. When the number of samples reaches the set number of samples, the sampling is withdrawn.

Start bottle number: the first sample bottle number after the equipment is started, the bottle number corresponding to the sample bottle must have no water before starting, otherwise the sample cannot be retained;

Mixing number: refers to the number of samples retained in the same sample bottle. If the number of mixed samples is equal to 1, it is no mixed collection, that is, only one sample can be left in a sample retention bottle. If the number of mixed samples is greater than 1, that is, the number of times can be set in the same bottle. Note: The number of mixes is multiplied by the sample volume, and is not greater than the volume of a single bottle.

Start now

If you need to start sampling, in non-"guest" mode, click the Start Now button, if the parameter settings are reasonable, the device will enter the operation interface, and start sampling.

If the parameter setting is unreasonable, the Parameter Setting Failure dialog box is displayed, and the corresponding parameter is set again.

Start sampling at a scheduled time

If you need to start sampling at a scheduled time, set the pre-start time, and then click the "Timed Start" button under the non-"guest" user, if the time setting format is correct and the pre-start time is greater than the system time, the device will automatically switch to the standby interface and enable the timing icon, and the system time will start sampling after the system time reaches the preset time.

If the time setting format is incorrect, or the pre-start time setting is less than the system time, the date setting failure dialog box will be displayed, and the date parameter will be set again, and the above operation will be repeated.

5.2.3 Sampling Mode - Timing Scale

Figure 5.4 - Sampling Mode-Timing Scale

Timed Proportional Sampling Mode: Cyclic sampling at fixed intervals. At the end of the interval, according to the cumulative flow rate and the sampling ratio, the sampling volume is calculated, that is, the cumulative flow multiplied by the sampling ratio. The device starts to retain samples, the number of samples is 1 time, and the cumulative flow rate is reset to zero, and the previous action is repeated. When the number of samples reaches the set number of samples, the sampling is withdrawn.

For example, in the interval time, the cumulative flow rate is 100 tons, the sampling ratio is 1:1000000, and the sampling volume is: 100*1/1000000 tons, that is100 ml.

To start the sampling operation, refer to the "Constant Flow Quantitation" startup operation.

5.2.4 Sampling mode - timed quantification

Figure 5.5 - Sampling Mode - Timing Quantitation

Timed Quantification sampling mode: Cyclic sampling at regular intervals. After the device is started, a sample is performed to sample the volume, and then the interval time is entered and the previous action is repeated. When the number of samples reaches the set number of samples, the sampling is withdrawn.

The number of mixed mining refers to the meaning of "fixed flow quantitative" mixed mining.

To start the sampling operation, refer to the "Constant Flow Quantitation" startup operation.

5.2.5 Sampling Mode - Quantitative

Figure 5.6 - Sampling Mode - Quantitation

"Quantitative" sampling mode: After the device is started, the sampling sets the sampling sample and ends the sampling. This sampling mode can be used to detect the amount of samples.

To start the sampling operation, refer to the "Constant Flow Quantitation" startup operation.

5.2.6 Sample retention mode - excess sample retention

Figure 5.7 - Retention Mode - Excess Retention Pattern

The sample retention mode is different from the previous four sampling modes. The mode is divided into two parts, the buffer tank is watered, and the sample is retained beyond the standard.

Pump water from the buffer bucket: The pump cleans the external water and pumps it into the buffer bucket;

Exceeding the standard retention sample: After the water is ready, wait for the external analyzer to exceed the standard sample retention signal, and if the command of the excess sample retention signal is received during the waiting time of excess drainage, the excess sample retention signal will be carried out; If all bottles are full, it is not possible to retain samples; If the time is greater than the judgment time of exceeding the standard, and less than the excess drainage time, the signal of the contact exceeding the standard sample retention is received, and the sample retention exceeding the standard is also carried out. Excessive sample retention is not possible at other times. If the time is greater than the sum of the judgment time and the discharge time, the buffer bucket will automatically empty the water sample.

After the device is powered off, it will automatically enter the emptying state when it is powered on again, and enter the standby state after the emptying is over.

5.2.7 Retention mode - active - mixing exceeds the standard

Figure 5.8 - Retention Mode - Active Mixing Exceededs

The mode is divided into two parts, the sampling bucket mixed sampling module, and the sample retention bucket exceeding the standard sample retention module.

Description of the "Active-Mixed Exceeding" sampling mode:

Over-the-top mode:

Exceeding the standard retention of the sample - the sample retention bucket enters the state of exceeding the standard after the water is ready;

Synchronous sample retention - the sample retention bucket is directly carried out after the water is ready;

Sampling bucket mixing sampling module: The sampling bucket is mixed sampling according to the set time interval, and when the sampling times reach the set number of times, the sampling bucket water is automatically synchronized to another sampling bucket, and then continue to followSet the time interval for sampling barrel mixed sampling;

Sample retention bucket exceeds the standard retention module:

After the sampling bucket meets the water collection setting, it is converted into a sample retention bucket, and the water in the sample bucket is fed into water and stirred;

Carry out active sample supply;

Instrument start signal output (relay signal + start command);

Wait for the external analyzer to retain the sample out of the standard, and the retention logic is the same as the excess retention of the sample.

This sampling method runs continuously at fixed intervals and cannot be automatically stopped. It can be stopped by sending an over-standard stop command, or manually operated by the interface;

After the device is powered off, it will automatically enter the emptying state when it is powered on again, and start sampling again after emptying.

Note: The judgment time of exceeding the standard must be less than the time of excess drainage

5.2.8 Retention sample mode-passive-mixed exceedance

Figure 5.10 - Sample Retention Mode - Mixed Excess Passive

This mode is the same as the Hybrid Excess Active mode, with the following differences:

5.2.9 Sample supply on the hour

Figure 5.11 - Sample retention mode - Sample supply on the hour

After the Hourly Feeding Enable is activated, the active mixing exceeds the standard and the sample supply process will not be started until the sample setting time is reached after the water sample is collected.
