This morning, after the NI Payload intergration, we checked the electrical continuity and insulation towards the tower for the following cables: S1 and S2 (marionette coils); U1 (Ring Heater); U2 (Ring Heater motors); U3 (mirror coils for sensing and PT100 on marionette coil); V1 (mirror coils); V2 and V3 (marionette motors); Z2 (temperature probes on mirror coils and on ring heater).

The test was successful: no electrical discontinuities or short circuits towards the tower were found.
