The Oscilloscope function (Figure 3-7) enables you to record data in two channels and to print output
voltages, output currents, inverter currents and the PV generator voltage. The right to use this special
function is reserved for Siemens customer service personnel.
The trigger control function enables you to choose the events which will trigger measured data
recordings. A measurement can be triggered by a malfunction, a grid (mains) failure or when the inverter
is switched on or off. You can also manually trigger a recording.
You can set the X axis scaling to one of three values:
voltages, output currents, inverter currents and the PV generator voltage. The right to use this special

You can set the X axis scaling to one of three values:
Fine:
approx. 2 ms per division
(scan rate 12 kHz with 255 pixels = 21.25 ms)
Medium:
approx. 25 ms per division
(scan rate 1 kHz with 255 pixels = 255 ms)
Coarse:
approx. 100 ms per division
(scan rate 250 Hz with 255 pixels = 1020 ms)
