The surface irregularities of a bearing rotating at high speed are converted to voltages by a sensor and recorded on an LR Series recorder. Because the speed of bearing rotation cannot be slowed for this measurement, data is captured first to an IC memory card at a fast sampling rate of 135 Hz. On playback the readout rate is set to 3 Hz, recording the surface profile on a time axis expanded by 135/3 = 45 times for analysis.

A voltage of 750 V is applied to an electrolyte used in capacitors, and the saturation characteristic curve is drawn for each position on the test material. Although with conventional analog recorders it was possible to read from the chart the voltage remaining after some elapsed time, by combining an LR recorder and a timer the numeric values can be printed out automatically.

Tests the effect of power supply voltage variations on copy machine performance. The test parameters (voltage, frequency) are varied using a power supply simulator, and the temperatures and circuit voltages in the copy machine are input directly to an LR recorder.
The power supply simulator and LR recorder settings are uploaded the computer together with the measurements via GP-IB communications to analyze machine performance under voltage variations.

By recording temperatures, pressures, flowrates and other variables in a pilot process on an LR Series recorder, the data can then easily be uploaded to a personal computer via a GP-IB link while monitoring them on the recorder. The process characteristics can then be analyzed on the computer.
