怎么校准U24-001电导率测量记录仪数据
U24-001主要参数:
电导率
标准量程:低量程0~1000μS/cm;全量程0~10000μS/cm
扩展量程:低量程0~2500μS/cm;全量程0~15000μS/cm
精度(在标准量程):3%读数或者5μS/cm
分辨率:1μS/cm
响应时间:1s(90%变化)
A :
a. 使用一个被校准的领域传导性仪表,测量具体导率(对25C被调整的传导性被稳定的)水,在日志记录器被发射了,部署之后和温度(大约15分钟)。 记录具体导率价值(微Siemens/cm),日期和时刻。
b. 在部署的结尾,使用被校准的领域传导性仪表测量具体导率和在去除日志记录器之前记录具体导率价值(微Siemens/cm),日期和时刻。
c. 一旦去除日志记录器,并且下载数据,您能使用传导性助理处理数据,为任一种渠道计算具体导率对时间使用一个可选择的温度系数2.1%/ oC,为盐水,每EN27888的自然水报偿或者顾客可选择的温度系数。 选择的温度补偿必须匹配领域传导性仪表使用的温度补偿。
d. 校准数据,在传导性助理的定标箱子:
1. 精选的“用途测量了点为定标”。
2. 检查“开始分度点=”箱子并且进入您在步骤a.测量的具体导率价值。 在下落下来菜单为“测量时间”选择第一日期/时间在您的登记日期以后并且从步骤a.计时。
3. 检查“结尾分度点=”箱子并且进入您在步骤b.测量的具体导率价值。 在下落下来菜单为“测量时间”在您的登记日期之前选择第一日期/时间并且从步骤b.计时。
4. 点击“创造新系列”看输入和被处理的或被校准的数据的剧情。 传导性助理可以重新开动许多次,有和没有定标数据,因为它不影响下载,原始数据从日志记录器。
e. 您能现在清洗传感器和调遣日志记录器每个步骤a。 被描述的二点定标过程上面补尝传感器漂泊和传感器弄脏。注:广州市骏凯电子科技有限公司是美国ONSET公司HOBO记录仪大中华区代理商!

A:
a. Using a calibrated field conductivity meter, measure the specific conductance (the conductivity adjusted to 25C) of the water after the logger has been launched, deployed, and temperature stabilized (approximately 15 minutes). Record the specific conductance value (micro Siemens/cm), date, and time.
b. At the end of the deployment, use the calibrated field conductivity meter to measure the specific conductance and record the specific conductance value (micro Siemens/cm), date, and time before removing the logger.
c. Once the logger is removed and the data is downloaded, you can process the data, using The Conductivity Assistant to calculate for either channel the specific conductance versus time using a selectable temperature coefficient of 2.1 % / oC, for salt water, natural water compensation per EN27888, or a customer selectable temperature coefficient. The temperature compensation selected must match the temperature compensation used by the field conductivity meter.
d. To calibrate the data, in the Calibration Box of the Conductivity Assistant:
i. Select “Use measured points for calibration”.
ii. Check the “Starting calibration point =” box and enter the specific conductance value that you measured in step a. In the drop down menu for “Measurement Time” select the first date/time after your recorded date and time from step a.
iii. Check the “Ending calibration point =” box and enter the specific conductance value that you measured in step b. In the drop down menu for “Measurement Time” select the first date/time before your recorded date and time from step b.
iv. Click “Create New Series” to see plots of the input and processed/calibrated data. The Conductivity Assistant can be rerun many times, with and without calibration data, because it does not affect the downloaded, raw data from the logger.
e. You can now clean the sensor and redeploy the logger per step a. The two point calibration process described above compensates for sensor drift and sensor fouling.
