nel C. For this purpose, set the switch to "HIGH”. If the measured

signals have a high amplitude (88 Vrms = 250 Vpp max.) set the

switch to "LOW”. In doing so, the measurement input is not overrun

(= overdriven).

B4 Adjusting the sampling time and resolution (last digit)

By applying the switch "GATE TIME” and the push-button "RESO”

you can change the sampling rate and the resolution for the three

channels "A”, "B” and "C”. This is done as follows:

Set the switch "GATE TIME” from "FAST” to "SLOW”. Immediately

afterwards, press the push-button "RESO” (= resolution). Subse-

quently, "—SEL.1—" appears on the display. If you apply the push-

button "RESO” again, "—SEL.2—" is displayed. In this context,

observe the following table:
