Using the Bestselling dataTaker Data Loggers

CHESTERLAND OH - Many measurement instruments do not have a linear measurement scale, and require a more complex equation to properly scale them to engineering units in a dataTaker data logger. However, you can use Microsoft Excel to create the correct polynomial equation using the calibration sheet included with these devices. All that's required is Microsoft Excel (or Openoffice.org Calc), and the calibration sheet for the measurement device, which in this case will be for a thermistor.

The calibration sheet that you receive will have a table of physical measurements and actual signal measurements that will look something like this:
Degs F -50 -25 0 25 50 77 100 125 150
Ohms 61200 27575 13260 6805 3678 2001 1241 765.5 489.8


The bestselling dataTaker intelligent data logging systems feature universal input channels that can be used with a wide range of input signal types and records: Temperature, Voltage, Current, 4-20mA Loops, Resistance, Bridges, Strain Gauges, Frequency, Digital, Serial and Calculated Measurements. They also offer powerful alarm and programming capabilities to allow the loggers to process measurements and initiate actions on their own. Communications features include RS232 with modem support, Ethernet and USB memory stick ports to connect locally, remotely or over the Internet. The web interface allows users to configure the dataTaker datalogger, access logged data and see current measurements as mimics or in a list using a web browser. FTP provides data directly to your office over the internet or mobile phone network without the need for polling or specific host software.
