Exporting Logger Data; Printing The Logger Data; Calibrating The Logger - Omega Engineering OM-70 Series User Manual

Exporting Logger Data

You can use the Interface Software to export sample data to a text file or to a Microsoft Excel file.
•
To export the data to a text file, select Export -> Text File from the File menu.
•
To export the data to a Microsoft Excel file, select Export -> Excel File from the File menu.
The file exported to Microsoft Excel is an Excel .csv file. The easiest way to open this file in Excel is to just double
click on the created file.
When you first open the .csv file in Excel, the Date Time column will be in a strange format. To convert to a normal
time and date format follow these steps:
1. Select the entire Date Time column.
2. While the cursor is in the column, click the right mouse button and select Format Cells.
3. Under Category: select Date or Time, then choose the format that suits you in the Type: column.
4. Click OK when done.

Printing the Logger Data

The Interface Software can print the data graph and the data sample list. To print, select Print from the File menu.
You can also view how your data will be printed using the Print Preview option from the File menu.
Graphs are printed as they appear on the screen. This includes the current zoom detail, marking of sample points,
etc (see Working with the Data Graph for more detail).
For the sample listing printout, you have an option to limit the printing between specific date and time. When you
select to print or print preview the sample listing, a date and time selection window will be displayed:
Only the data samples within the specified dates will be printed.

Calibrating the Logger

Your logger is factory calibrated to an accuracy given in the device specifications. However, there may be times
when you wish to adjust the calibration of your logger. The Interface Software provides you with the ability to
perform a single point offset calibration. This calibration can be used to increase the accuracy of your device for a
restricted data range. For instance, if your application calls for logging temperature between 20°F and 32°F, you
may want to calibrate your logger at 26°F.
Warning: Calibrating the logger erases the data that is stored in logger memory.
Calibration only can be performed when the device is not logging. To calibrate your logger, select Calibrate...
from the Logger menu. For extra security, calibration is password protected. You must enter the correct password
in the Calibration Password window before you're allowed to calibrate the unit. The logger has been preset at the
factory with no password, so if this is the first time you are calibrating the device, leave the password field blank.
The Password Calibration window also allows you to change the password.
Once the password is entered correctly, a window asking you to select the channel to calibrate pops up. Select the
