    • A multi-wavelength light emitting and receiving apparatus for monitoring connections by optical fibers comprising a case, an emission section, a reception section, a keyboard for selecting operating modes and measurement scales, a display arrangement, a processing unit including a microprocessor connected to the emission section, the reception section, the keyboard and the display arrangement, and a feed. The emission and reception sections are mounted in a drawer provided with a connector that can be inserted into a complementary connector provided in the case, this latter containing the keyboard, the display arrangement, the processing unit, and the feed. It also contains at least one more emitting/receiving drawer equipped with a connector that can be inserted in the said complementary connector of the case and contains another controlled current source, another light-emitting diode having an emission wave-length different from that of the first light-emitting diode and connected to the other controlled current source, another photoreceiver having a spectral window covering that of the other light-emitting diode and another amplifier connected to the outlet of the other photoreceiver. Each amplifier has a gain adapted to the response of the photoreceiver and associated with the wavelength emitted by the emitting diode situated in the corresponding drawer, such that at identical levels of light powers respectively emitted by the emitting diodes and respectively received by the photoreceivers the amplifiers deliver output signals having the same levels.

    • A Hall-effect current clamp, in which the constant-current generator (13) supplying the Hall-effect cell (8) comprises an operational amplifier (15) which has an internal-voltage reference (17) and which pilots a transistor (Q1) mounted in emitter follower in series with the cell (8), such that the current which traverses it is on the order of 1 mA. At the output of the measurement amplifier (14) of the clamp, a dividing bridge (P1,R5) whose intermediate lead is connected to the inverting (-) input of the amplifier (14) permits obtaining a supplementary amplification of the output signal of the clamp at the price of a low current consumption. Thus, the total current consumption of the clamp is maintained at a very low level, thereby providing a considerable increase in the life span of the batteries (9) used to supply the clamp.
