Claims (2)
- 受信機から延びる伝送路に感知器が接続されている受信機システムの試験方法において、前記感知器の試験を行なうのに、受信機と感知器との間に、感知器と通信を行なうことが可能であって出力インピーダンスの低い電源手段が設けられている試験器を前記受信機と並列に接続し、前記試験器から通信パルスを送出して前記感知器との間で通信を行なわせて、感知器の試験を行なうようにしており、前記試験器は、前記感知器との間で試験のための通信を行なうときには、出力インピーダンスの低い電源手段から電源を供給することを特徴とする試験方法。
- 請求項1記載の試験方法において、前記試験器と前記感知器との間で通信を行なわせて、感知器の試験を行なう際、伝送路に終端コンデンサが設けられている場合に、感知器から試験器へ伝送する通信パルスのパルス幅を、試験器から感知器に伝送される通信パルスのパルス幅よりも短かくすることを特徴とする試験方法。
