Continuous

250 Vrms, Measurement Category II (Note 4)

Withstand

2,300 Vrms, verified by a 5 sec dielectric withstand test

Channel-to-channel isolation

Continuous

250 Vrms, Measurement Category II (Note 4)

Withstand

1390 Vrms, verified by a 5 sec dielectric withstand test

Note 3: Connect only voltages that are within the limits specified in this table.

Note 4: Measurement Category II is for measurements performed on circuits directly connected to the

electrical distribution system. This category refers to local-level electrical distribution, such as

that provided by a standard wall outlet, for example 115 V for US or 230 V for Europe.

Caution! Do not connect the device to signals or use for measurements within Measurement Categories
