Measuring Start and finish measuring Press START. • Data is recorded to HiLogger memory. It is then automatically saved to the CF card. Recording stops one day after starting. • To stop recording early, press STOP. • To view waveforms or numerical values while measuring, see "Viewing Waveforms or Numer- ical Values"...
Viewing Waveforms or Numerical Values Viewing Waveforms or Numeri- cal Values This section describes how to view waveforms and numerical values during and after measurement. Display Waveforms Press WAVE/DATA to display the Waveform/Value screen. The screens toggle each time the key is pressed. Gauges can be displayed, and numerical values and waveforms can be viewed simultaneously.

Viewing Waveforms or Numerical Values View Measurement Values Measured values can be viewed as numerical values, waveforms and numerical values, or as numerical values and comments. Displayed numerical values are those of the current input signals. To display waveforms and numerical values Select [Wave+Value].

Observing Data on a Computer Observing Data on a Computer Converting waveform data to text format To analyze data using a spreadsheet program such as Excel, first convert the waveform (binary) data to text (CSV) format using the HiLogger or Logger Utility program. This procedure describes how to convert to text format using the Logger Utility.

Observing Data on a Computer Save in Text (CSV) Format In the menu bar, click [File] [Save File in Text Format] [Save File in Text Format] dialog appears. Select the sheet of measurement data to save. Select the check boxes for the channels to save. Set the following: [File name] Enter any file name.

Observing Data on a Computer Computer Connection (for communication) Connect a computer to the HiLogger with a LAN or USB cable to view recorded data and make HiLogger settings on the computer. Use the supplied Logger Utility application program to monitor waveforms, numerical val- ues, and warning output states in real time, and to collect measurement data from up to five HiLoggers on one computer.
