The pen servo unit takes advantage of an ultra-small, rack-and-pinion stepping motor. The servo unit is smaller and consumes less power than previous models.
Splash-proof Front Door (conforms to DIN 40050-IP54)
The front door meets DIN 40050-IP54 standards in panel-mount installations.
High-Voltage Solid State Scanners

High withstand voltage semiconductor relays have been adopted for scanners that switch the input signal. They enable high speed scanning of six dots per second, increase the life of the scanner, and reduce noise.
Use of ASICs

The recorders feature a high degree of functional integration through Yokogawa's renowned ASICs (application specific integrated circuits, or custom ICs). They allow for reduced power consumption, increased lifespan of components, and suppressing of heat emmisions.
Safety/EMC Standards
EMI testing LAB in Yokogawa
Yokogawa's highly reliable industrial recorders support safety and EMC (electromagnetic compatibility) standards. And of course, the µR conforms to the European CE marking standard.
Lightweight
µR10000

*Individual terminals are removable, making wiring and maintenace easy.
µR20000


Uses a large, easy-to-view VFD 101 x 16 (µR10000), 181 x 16 (µR20000) full dot matrix display. All settings are interactive, and supported by the navigational display, offering easier to read selections and superior ease of operation.

All settings are interactive, and supported by the navigational display, offering superior ease of use.
This µR reflects advances in the chart cassette and internal illumination. Also, our new disposable pen (pen model), plotter pen, cassette ribbon (dot model), and chart paper maintain compatibility with previous models.

By using a high intensity white LED and light-diffusing rod for the internal illumination, the visibility of the chart section has been greatly increased.
The chart cassette is equipped with a chart-ejection function. You can write memos on the chart and check the historical trend during recording.

This function enables minute adjustments when a certain correction is necessary due to deterioration of a sensor, or if measured values fall within the accuracy range but fluctuate relative to the displayed values on other instruments. Input signals are corrected based on a specified broken line, and its values are measured.
Number of Set Points
You can select the number of points that make up the segments (including the start and end points) in the range of 2 to 16.
Using revision values


Corrected value (B4) of the fourth set point = a ? b
Example of the Input Values
| Input Value | Corrected Value | Revision Value | Absolute Value |

| 9.8° | 10.0° | 0.2° | 10.0° |
| 90.5° | 90.0° | -0.5° | 90.0° |
The unit can be powered under 24 VDA or 24 VAC.
| Supply Voltage | Max. |
|---|---|
| 24 VDC | Approx. 50 VA |
| 24 VAC (50/60 Hz) | Approx. 60 VA |
This model comes with a convenient carrying handle and portable power cord.
