The best-selling LR Recorder Series has revolutionized the pen recorder world with its outstanding reliability and performance. How was it done? Electrical contacts and gears were eliminated in the recording mechanism. Data processing was digitized. A full range of models of up to 12 pens was developed. A memory function to facilitate PC-based data recording and analysis was created. And a whole range of application software was written. In today's PC-driven world, only the LR recorder truly delivers the required functionality. |

- Crisp color analog recording in up to 12 colors
As simple to use as an analog pen recorder
The LR series offers easy dialog-based operation on a large vacuum-tube fluorescent display and multiple display functions.
- Wealth of digital printing and analog recording functions
Packed with a wealth of digital printing functions, including zone recording, partial compression and enlargement recording, a rapid pen response of 1600 mm/s and a phase synchronization function, the LR series captures the target event faithfully, records it, and makes playback a cinch.
- Multiple measurement type
The LR series offers DC voltage, thermocouple, and RTD universal inputs, computation functions, IC memory card, a 3.5-inch FDD, and application software to cover every type of measurement.
- 3.5-inch floppy disk drive (option)
- Windows (32-bit) application software
Yokogawa's genuine software lets you set the measurement range and recording conditions, control the motion of the pen such as pen up/down, and even record and analyze the data on a PC.
- 1600 mm/s Maximum Pen Speed
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
The recording pens of the LR series 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.
- Auto Sweepout of Pen Offset Data
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.
