waveform corresponding to input signal on chart paper which moves at a constant speed by pens which are automatically balanced by means of servo system; a method known as a self-balancing method or so called zero method.

Based on years of our experience, U-228 recorder was developed giving emphasis on substantial specifications and improved performance and versatility in operation in addition to consideration on style as well as compactness and light weight. As a result, this recorder has many outstanding features, as described in the following.

FEATURES

２．

Power voltage can be easily changed among 5 voltage ranges so that U-228 is applicable to power voltages

（１）

of every country in the world.

Use that inclines from a desk-top type on a record horizontal side, and 12° changes the angle into a

（２）

wall hanging type to which the record side is vertical is possible. The limited space can be effectively used.

In addition of being compact and light weight, it is designed as being easily carried by one hand from

（３）

one place to other wherever necessary.

Having an extended writing panel, the state of recording can be easily observed.

（４）

Having no obstacles on the right side of the writing panel, entry of data into the chart paper is easy.

（５）

The pulse motor is adopted for the record paper feed.

（６）

Abundant sending speeds at 23 velocities every 24 steps can be freely selected.

Driving stop from the outside is also possible. can do the record paper feed proportional to the frequency in the external signal source

Equipped with a fast forward switch that makes the position correction of the chart paper easy.

（７）

Rewind switch allows the chart paper to be easily retracted to a desired position.

（８）

Because the chart take-up device is designed so as to be optionally built into the recorder without having to

（９）

externally attaching it, only a minimum space is required for the operation (optional).

Equipped with a chart paper end alarm, the end of the chart paper is notified by a buzz and a flashing lamp.

（ 10）

Using cartridge type fiber tip pens, such trouble as sudden "out of ink" cannot happen during the recording.

（ 11）

The maintenance is easy, too.

Adoption of 1kHz modulation type servo amplifier and direct current servo method.

（ 12）

It has an excellent response, the noise characteristic, and the temperature characteristic.

The polarity of signal input can be changed by a switch.

（ 13）

14 Equip a proofreading power supply.

（）

A check of fullspan voltage accuracy and proofreading can be performed easily.

15 Having a superimposed event marker as a standard feature, entries of marks can be made on any part of the

（）

chart. This feature is also helpful in knowing the recorded time lag between the pens.

16 Adoption of film potentiometer and it equips it with the shake slice protection circuit.

（），

Reliability has improved further.
