Zangen-Amperemeter Graupner 1958 This handy clamp ammeter can measure D.C. currents in the range 100 mA to 199.9 A without requiring electrical contact and without interrupting the circuit. This range covers virtually all currents which occur in modelling, including electric motors, speed controllers, electric sub-assemblies etc. Indispensable when you are trying out different aircraft propellers, boat propellers and gearbox ratios in the quest foroptimum efficiency. The ammeter features an integral memory which »freezes« the momentary value during the measurement process. Combining this ammeter with the MX–170B Digital Multimeter, No. 1957, produces an all-purpose measuring set for the demanding electric power professional. You can use the devices to check and measure virtually all current and voltage parameters in the fields of R/C electric flight and R/C electric boats. Measurement range ± 0 ... 199.9 A
