XY recorder

Japanese: XY 記録計 - えっくすわいきろくけい
XY recorder

...The recording accuracy is about ±0.5% of the recording width, and the upper limit of the frequency of voltage changes that can be recorded is often up to 1Hz. Applications of auto-balancing recorders include multi-point recorders and XY recorders. Multi-point recorders measure by switching between many measurement points in sequence, and the pen changes color in sync with this switching to record the points. ...

From [Electric Meter]

…An automatic balancing recorder uses the principle of a potentiometer or bridge to detect and amplify unbalanced voltages, automatically balancing them with a servomotor, and records the motor's movement with a pen or a dot on the recording paper. An XY recorder is one in which two sets of this mechanism are set at right angles to each other and record the relationship between the X and Y quantities. Pen-writing and electromagnetic oscillographs have light moving parts and can record up to relatively high frequencies. …

…記録の精度は記録幅の±0.5%程度,記録できる電圧変化の周波数上限は1Hzまでのものが多い。 自動平衡型記録計の応用に多点記録計とXY記録計がある。多点記録計は多くの測定点を順次切り換えて測定し,ペンもこの切換えに同期して色を変えて打点記録する。…

【電気計器】より

…自動平衡記録計は電位差計またはブリッジの原理を用い,不平衡電圧を検出,増幅し,サーボモーターで自動的に平衡をとるもので,モーターの動きを記録紙上にペンまたは打点で記録するものである。この機構を2組互いに直角方向に用意し,X,Y2量の関係を記録するものがXY記録計である。ペン書きおよび電磁オシログラフは可動部を軽くして,比較的高い周波数まで記録できるようにしたものである。…
