Using the tables “Basic/Reinforced insulation test voltages in accordance with IEC
61010-2-030:2017”,itcanbeconcludedthatthisspecicationinformstheuserthat
a high voltage input within the device has passed the insulation test; 5 sec at 6600 V
RMS for the rating of 1000 V CAT IV basic insulation.
For a voltage channel, input to chassis has passed the isolation tests of 5 sec at
7400 V RMS for the rating of 1000 V CAT III reinforced insulation. Tested up to 7400 V
RMS for 5 s, the reinforced and double insulation allows for safe measurements up to
1000 V CAT III (without probes) from voltage channel to chassis.
