How To Maximize RPM Measurement Resolution
Data Logger > Graphtec > GL820 A Graphtec GL820 data logger user could not understand why the resolution of the instrument was not better than 60 RPM. He connected the output of a reflective tape sensor to a discrete input programmed for REVOL, which applies an automatic scaling operation as follows: Clearly from the above Read More
Create an Excel Macro to Add Seconds to DI-160 Event Data Logger Files
Data Acquisition > Event, State, Count > DI-160 Microsoft Excel automatically assigns a date/time format to files generated by the DI-160 Event, State and Count data logger that does not include seconds (mm/dd/yyyy, hh:mm). As a result, events that occur more often than once a second appear in the data file with the same date/time Read More

There are two factors that affect TC cable length: 1. Noise 2. Inaccuracy The longer the cable the more susceptible it is to radiated noise. The TC represents a low impedance source, Read More
