8845A/8846A Users Manual cycle time is longer than it is when using the 20 Hz filter. 20HZ Provides higher measurement accuracy on ac signals between 20 Hz and 200 Hz. However, the measurement cycle time is longer than it is when using the 200 Hz filter. 200 HZ Provides accurate measurements on ac signals 200 Hz and above. 2ND MEAS Cycles the secondary display through the measurement functions listed below, and then off. When a second measurement function is selected, the 2ND MEAS soft key label is highlighted. IDC - Displays the dc current the ac signal is riding on. Frequency - Displays the frequency of the ac signal on the Meter's Input HI and LO connectors. Measuring Capacitance (8846A only) The Fluke 8846A is capable of measuring capacitance from 1 pF to 100 mF (0.1 F). To make a capacitance measurement: 1. Press C. An example of the capacitance display is shown below. 0.000 nF F1 F2 F3 F4 F5 2. Connect the Meter's test leads as shown in Figure 4-6. caw10f.eps INPUT V 2W/4W HI SENSE 4W HI 1000 V CAT I 600V CAT II 300 V LO LO 1V FUSED 100 mA 10 A REAR FRONT 4-12 Figure 4-6.
