    • An error correcting device for a multiplier of the time-division multiplication type comprising a modulator, a switch and a filter. Another switch is responsive to a time-base delivering periodically a zero signal to the modulator; a circuit memorizes and detects the difference between the product xy vitiated by switching and shifting errors and the errors themselves. The memories are of the capacitor and amplifier type, and the subtraction is obtained through the opposite of the voltages of said capacitors. This device is applicable more particularly to high-frequency, wide-range precision wattmeters adapted for d.c. calibration.

    • 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.
