Sampled Values (Current and Voltage Values)

I would like to know how to convert the values shown by WireShark from the IEC61850 Sampled Values? Frame 1: 146 bytes on wire (1168 bits), 146 bytes captured (1168 bits) on interface \Device\NPF_{C1BF5A3C-D185-4BAB-B05D-DB7CFC4D1085}, id 0 Ethernet II, Src: Ent-Empr_f1:44:9c (00:90:cd:f1:44:9c), Dst: Iec-Tc57_04:00:00 (01:0c:cd:04:00:00) IEC61850 Sampled Values APPID: 0x4001 Length: 126 Reserved 1: 0x0000 (0) Reserved 2: 0x0000 (0) savPdu noASDU: 1 seqASDU: 1 item ASDU svID: SAMUA2MU0101 smpCnt: 440 confRev: 3 smpSynch: none (0) PhsMeas1 value: -90 quality: 0x00000000, validity: good, source: process value: 36 quality: 0x00000000, validity: good, source: process value: 136 quality: 0x00000000, validity: good, source: process value: 75 quality: 0x00000000, validity: good, source: process value: 24 quality: 0x00000000, validity: good, source: process value: 33 quality: 0x00000000, validity: good, source: process value: 23 quality: 0x00000000, validity: good, source: process value: 0 quality: 0x00000000, validity: good, source: process value: 0 quality: 0x00000000, validity: good, source: process value: 0 quality: 0x00000000, validity: good, source: process
