Connection socket measuring current transformer • ••••• M1-M3= Measurement time point t1 = typ. 270 ms (start up delay to drive outputs) After starting the test, the charging system must ensure that the outputs are set correctly at the measurement time points M...: M1: Switch2 = HIGH M2: Switchl = HIGH M3: Switch2 / Switchl = LOW £ The offset measurement only takes place when, after the test, both outputs are LOW (Mi, M2). If the outputs are not set correctly at the measuring times M..., the RDC104-4 must be regarded as defective.
