Measuring the standby heating
• Switch off the system
• Remove the top cover and, in the case of MOBILETT XP Digital, place it on its side on a
table or similar surface (do not disconnect any cable connections).
• Oscilloscope channel 1 at D916 TP “I” (7) and D916.GND (1) - resonant filament cur-
rent.
Oscilloscope setting: channel 1 = 2 V/div, trigger channel 1, trigger stage 1.5 V, 100
µs/div
• Switch the system on
