1600 mm/s Maximum Pen Speed
  frequency
For the fastest possible response, YOKOGAWA developed new proprietary technologies for the LR Series, and raised the maximum pen speed to 1600 mm/s, nearly twice that of the previous fastest.
In terms of frequency response, this equates with nearly 3 Hz at full deflection and 6 Hz at small deflections. High-speed signals are thus recorded faithfully.
Disposable Felt-tipped Pens
  Pens
The newly developed recording pens of the LR12000E are special disposable felt-tipped pens with a long thin pen arm and a wide ink storage section, to enable the pens near the back of the instrument to be more visible. These pens have the same high-speed response and long life as conventional LR series pens.
Auto Sweepout of Pen Offset Data
  Auto Sweepout
When you use pen offset compensation, the recorder stores data to compensate for the pen offsets in order to record all traces in real-time. Thus when recording stops, the pens must continue recording until all the data is plotted. Auto sweepout saves you time by automatically increasing the chart speed during this interval - a real advantage at slow chart speeds. For example, at 10 mm/h chart speed on an 8-pen LR, it would take nearly three hours after measurement to record all the stored offset data. In the current LR Series recorders, however, touching the chart stop key automatically increases the chart speed to 200 mm/min and stops it after all pen offset data have been swept out. This takes just eight seconds. This new function, not available on previous LR recorders, has been added at the request of many users.
