Model 2700 Multimeter/Switch System User’s Manual Basic DMM Operation 3-45 Connections NOTE When using the front panel inputs, the INPUTS switch must be in the “F” (out) position. For switching modules, it must be in the “R” (in) position. Front panel input When using the front panel input terminals, connect the test leads to the INPUT HI and LO terminals as shown in Figure 3-17. Figure 3-17 FREQ and PERIOD connections for front panel inputs Model 2700 SENSE INPU HI 350 ! 1000 LO 500 AC Voltage Source INPUT FFF R FRONT/R 3A Input Impedance = 1MΩ in parallel with <100pF Caution: Maximum Input = 1000V peak, 8 x 107V•Hz Model 7700 switching module Connections for the Model 7700 switching module are shown in Figure 3-18. For this 2-wire measurement, channels 1 through 20 can be used.
