FREQUENCY RESPONSE FOR OUTPUT MEASUREMENTS
The Model 270 Series 2 has a capacitor in series with the
OUTPUT jack. This blocks the D.C. component of the cur-
rent in the measuring circuit, but allows the A. C., or desired
component, to pass on to the meter circuit. The blocking
capacitor placed in series with the A.C. voltage measuring
circuits alters the A.C. response. The above curves show
the frequency response of the 2.5, 10, and 50 volt ranges.
l. Set the function switch on the left hand side of the
front panel at A.C.
2. Connect the black test lead in the COMMON- jack and
the red test lead in the OUTPUT jack.
