OPENING THE DATA FILE WITH EXCEL®
Depending on the region and language setting of your PC,
measurement data might be formatted incorrectly by Excel® when the
data file is opened.
This is sometimes encountered with German set as the PC language, as
a German date format typically utilizes a decimal (DD.MM.YYYY). The
ODO200M utilizes a decimal as the radix, so a temperature of 31.1 is
sometimes interpreted by Excel® as 31. Jan when German is set as the
PC language.
If a data file is opened in Excel® and measurement data is incorrectly
interpreted as something other than a number, please follow these
steps:
1. Open a blank Excel® spreadsheet.
2. Go to the Data tab and select From Text.
3. Choose to Import the data file you have copied to your PC. Don't
select the original data file that is still on the instrument.

Possible Solution
1. Verify temperature readings are accurate.
2. Sample temperature should be
between 0 and 45 ºC, the temperature
compensation range for DO mg/L.
3. DO sensor not properly calibrated,
recalibrate the sensor.
4. Check sensor cap. Clean, rehydrate or
replace as necessary. Recalibrate.
5. Contact YSI Tech Support.
1. Sample dissolved oxygen concentration
is more than 20 mg/L or 200%, or
less than 0.0 mg/L or 0.0%.
2. Verify temperature readings are accurate.
3. DO sensor not properly calibrated,
recalibrate the sensor.
4. Check sensor cap. Clean, rehydrate or
replace as necessary. Recalibrate.
5. Contact YSI Tech Support.
