Page 89: Waveform Acquisition
5 Waveform Acquisition Based on the data that has been stored in the acquisition memory, the instrument performs various operations, such as displaying waveforms on the screen, computing, measuring cursors, and automatically measuring waveform parameters. This chapter explains how to set the number of data points to store in the acquisition memory (the record length), how to enable or disable the sample data averaging feature, and so on.
Page 90: Time Scale (Time/Div)
5 Waveform Acquisition Time Scale (Time/Div) This is a setting in scope mode. When the internal clock is being used, the time scale is set as a length of time per grid division (1 div). The selectable ranges are 1 μs/div to 30 s/div, 1 min/div to 30 min/div, 1 hour/div to 12 hour/div, 1 day/div to 5 day/ div.
Page 91 5 Waveform Acquisition How the Time Axis Relates to the Display of the Waveform There are 10 div along the time axis, and 1001 points (logical number of points, not the dots on the screen) are used to draw the waveforms. As such, if the display record length is greater than or equal to 2 kpoint, as shown in the figure on the right, the instrument draws the waveform by determining the maximum and minimum values at each fixed interval (P-P compression) and aligning them vertically at the same time position (total number of points: 2002).
Page 92: Acquisition Time, Record Time, Acquisition Length, Record Length (Acquisition Time, Record Time, Acquisition Length, Record Length)
5 Waveform Acquisition Sample Rate If you change the time scale, the sample rate also changes. The sample rate is the number of samples-per- second (S/s). * If the sample rate is comparatively low with respect to the input signal frequency, the harmonics contained in the signal are lost.
Page 93: Record Length (Record Length)

Page 96: Trigger Mode (Trigger Mode)
5 Waveform Acquisition Trigger mode (Trigger Mode) This is a setting in scope mode. The trigger mode determines the conditions for updating the displayed waveforms. There are four trigger modes. Auto Mode (Auto) If the trigger conditions are met before an approximately 50 ms timeout, the instrument updates the displayed waveforms on each trigger occurrence.

5 Waveform Acquisition Acquisition Settings (Acquisition Setup) There are acquisition settings. • Acquisition Mode (Acquisition Mode) • Acquisition Count (Acquisition Count) Acquisition Mode (Acquisition Mode) Select from the following. Normal Mode (Normal) Displays waveforms without processing the sampled data. Envelope Mode (Envelope) The instrument determines the maximum and minimum values among the data sampled at the maximum sample rate for each module at a time interval that is twice the sampling period (the inverse of the sample rate) of Normal mode, saves the values as pairs in the acquisition memory, and uses the saved value pairs to display...
Page 98: Acquisition Count (Acquisition Count)
5 Waveform Acquisition Acquisition Count (Acquisition Count) This is a setting in scope mode. The ranges within which you can set the waveform acquisition count are indicated below. If you select Infinite, the instrument continues waveform acquisition until you stop it using the START/STOP key. Changes to the number of acquisitions are not applied during waveform acquisition.
Page 99: Trigger (Trigger)
5 Waveform Acquisition Trigger (Trigger) Time Base (Time Base) Under the initial settings, the instrument samples the measured signals using the clock signal produced by its internal time-base circuit (internal clock). You can also use an external clock signal to control sampling. One data sample is stored to the acquisition memory at every pulse in the external clock signal.
Page 100 5 Waveform Acquisition Notes about Sampling Using an External Clock Signal • Roll mode display is not available in scope mode. • There is no function for dividing the frequency of the clock signal. • The time axis cannot be changed. To change the time-axis display range, change the record length, or zoom in on the time axis.
Page 101: Trigger Position (Position)
5 Waveform Acquisition Trigger Position (Position) This is a setting in scope mode. When you move the trigger position, the ratio of the displayed data before the trigger point (the pre-trigger section) to the data after the trigger point (the post-trigger point) changes. When the trigger delay is 0 s, the trigger point and trigger positions coincide.

Page 107: Waveform Acquisition (Start/Stop)
5 Waveform Acquisition Waveform Acquisition (START/STOP) When you start waveform acquisition, the instrument stores waveform data to the acquisition memory and updates the displayed waveforms each time it triggers. The acquisition memory is divided into many areas based on the set record length, and the maximum number of acquirable waveforms are stored in the memory. You can recall past waveforms that are stored in the memory by using the history feature when waveform acquisition is stopped.

Page 237: Appendix 4 About Shunt Calibration
Appendix Appendix 4 About Shunt Calibration Shunt calibration is a type of scaling in which the strain measurement gain is adjusted through the connection in parallel of a known resistance (the resistance for shunt calibration, hereinafter referred to as the shunt resistance) to the strain gauge.
Page 238: Shunt Calibration Procedure
Appendix • When correcting the gain on the positive side Shunt calibration relay circuit Shunt resistor, when (Built into the strain module. correcting the positive side Turns on and off automatically when shunt calibration is Bridge+ executed.) 120 Ω Bridge In–...
Page 239 • Because the strain gauge is attached away from the bridgehead, we recommend that you use twisted wire for extensions. • Use a bridgehead with high noise resistance. We recommended that you use a YOKOGAWA bridgehead (701957 or 701958); they are highly resistant to noise.
Page 240 Appendix Calculation of the Shunt Resistance To execute shunt calibration, you need to calculate the shunt resistance (Rs) and the expected strain (ε) in advance. For “P2-Y,” use ε as given in the equation below (normally a negative value). In the general method given for shunt calibration (the easy method), an error of 1 to 2% is introduced as the strain value (ε) increases. Therefore, use the detailed method whenever possible.

Page 243 Appendix Filter Characteristics (Time Delay) of the Smoothing Filter The smoothing filter is a moving average filter in which computation is performed in real time. The smoothing filter takes the simple average of the data whose data update rate is 1 μs (1 MHz) over 40 μs and performs moving average at 40 μs intervals. The computation interval of moving average is constant, independent of the instrument’s sample rate. The data computed at 40 μs intervals is linearly interpolated to 1 μs data and transmitted. The moving average order (the number of averaged points) is specified in terms of time. The maximum value is 25000 points (when the time is set to 1000 ms).
