a.c. current
40Hz to 1KHz
4mA to 400mA
10A
Ranges : 4mA, 40mA, 400mA, 10A (20A for 30 seconds)
Resolution : 1µA on 4mA range
Voltage drop : mA input: 800mV (max.),
10A input : 1V (max.)
Input protection
mA input : 1A, 600V, 10kA breaking capacity fuse (Bussmann BBS-1 or equivalent)
A input : 15A, 600V, 100kA breaking capacity fuse (Bussmann KTK15 or equivalent)
A.c. current conversion :
203 : Mean measured - R.m.s. value displayed
205 : A.c. coupling. True r.m.s. measurements. Calibration to r.m.s. value with sinusoidal a.c. current.
The accuracy specified is for full-scale deflection for sinusoidal currents and half-scale deflection for non-sinusoidal currents,
of frequencies less than 500Hz and form factors of up to 2.
