Title: Measuring instrument
Inventor: SUZUKI SHIGERU
IPC: G08C19/30
Filed: 1990-02-21
Abstract: PURPOSE:To suppress the breakdown of a detector, the interrupting operation of a main bias power supply, or the fusing of a fuse by connecting a current restricting resistor element to each diode in series. CONSTITUTION:When a short-circuit is generated in any one of detectors ch.1 to ch.n, a short-circuit current flows into the short-circuit generating detector, but since current restricting resistors 21a to 21n are serialy connected to respec tive diodes 9a to 9n, the short-circuit current can be suppressed by its correspond ing resistor. Since the inflow of an excess current can be suppressed, the short- circuit detector can be prevented from being broken. Even if the detectors for one channel are short-circuited, the main bias power supply 4 is not downed due to over-capacity, the detectors for other channels can be prevented from being disabled from detecting.
