1. What are my minimum system requirements?

EasyData will run on an Intel® Pentium® III or greater with Windows® 98, ME, and XP. It requires approximately 30 mb of hard disk space. Screen resolution must be greater than 800 X 600.

2. How do I change my screen resolution to use EasyData?

Your screen resolution must be greater than 800 by 600 to use EasyData. For Windows XP users: Click on Control Panel; click on ‘Display;’ click on the ‘Settings’ tab; increase screen resolution to greater than 800 by 600; click ‘Apply;’ click ‘Okay.’ There may be slight variations for non-Windows XP users. We are available for any additional help so please contact us at support@eurekaenvironmental.com.

3. What instruments does EasyData work with?

EasyData can download and open files from the following Hydrolab™ multiprobes: DataSonde™ 4a, MiniSonde™ 4a, DataSonde™ 4 or MiniSonde™. EasyData can download and open files from the following YSI® multiprobes: 6600, 600XLM, or 6920.

4. What if I have another instrument?

Please contact Eureka and we will let you know the approximate availability.

5. Will EasyData delete the file on the sonde after downloading?

No. Files must be deleted using the manufacturer’s software.

6. How does the drift correction work?

EasyData’s unique Drift Correction lets you compensate for any changes in a sensor’s calibration that may have occurred during an extended field deployment. The drift might be caused by a combination of sensor drift, sensor fouling, and sensor failure.

All you have to do is fill in pre- and post- calibration information. Once you have filled out the chart, EasyData calculates each sensor’s rate of drift and shows that drift as percent of reading per day.

Suppose your post-cal conductivity reading is 1.426 in a 1.412 standard solution and that your field deployment is 10 days. Your drift is:

(1.426 – 1.412)/1.412 / 10 days =
0.014 / 1.412 / 10 days =
0.1% per day

Once the drift rate is determined, EasyData applies the opposite of that drift rate to the data linearly over the deployment time. In the conductivity example, the conductivity readings at the beginning of Day One will not be corrected because no time has elapsed (i.e., the sensor is assumed to be calibrated when it is first deployed). At the end of Day Ten, however, the conductivity reading is lowered by 1% (10 days x 0.1%/day) because our post-cal shows the conductivity reading at the end of the deployment to be biased upward by 1%.

Suppose you wish to correct the conductivity of 0.500 reading taken at the end of Day Five. That’s exactly half-way through the deployment, so EasyData will effectively apply half the total correction indicated by the post-cal:

5 days x 0.1%/day x 0.500 = 0.0025

0.500 – 0.0025 = 0.497

The corrected reading is thus slightly lower, at 0.497.

Notes:

1. Corrected data is shown in italics on the screen and when exported.
2. EasyData assumes that your calibration is correct at the beginning of the deployment.
3. EasyData assumes that your post-cal data closely describes the condition of the sensors at the end of the deployment – so don’t wait long, or clean the sensors, before making your post-cal.
4. EasyData assumes that sensor drift and fouling affect the sensors linearly with time.
5. Each practitioner must decide if the EasyData Drift Correction method is valid for his or her data and measurement situation.

7. Can I calibrate my instrument with EasyData?

Not at this time.

8. What is your upgrade policy?

We strive to keep you happy. Occasionally features may be added or bugs may be fixed in the software and will be followed by free product upgrades. Major revisions will be released as new versions which may require additional cost.

9. I’m skeptical. Can I try the software first?

Yes, after downloading, you have 30 days to try the software before being billed. To begin your free trial period or to request a hard copy of EasyData to be mailed to you, please click on the following link:
