Channel Operation; Lossless Data Recovery - Noraxon Ultium EMG System User Manual

Ultium EMG Hardware User Manual
Once sync is selected, the sync channel in MR3 will be displayed as a Sync channel in the
Measurement Configuration. Without sync, this channel appears as a Switch channel. By selecting the
sync channel, a signal channel will appear in the record displaying when the sync pulse is generated.

7.2 32 Channel Operation

Ultium supports measuring up to 32 channels via 2 separate 16 channel systems. Insert both systems
into the Hardware Setup, making sure to set each receiver to a different RF Network number. Use of
the Noraxon MyoSync device is also recommended to synchronize the data streams of the 2 devices.

7.3 Lossless Data Recovery

The Ultium System supports "lossless" data recovery. The sensors continue to capture and store data
(>8 hours of data) when communication is temporarily lost with the receiver. Once the record is
completed, the data can be recovered in real-time or at a later time using the Import function.
7.3.1 Real-time (Online) Recovery
Immediately following the record, MR3 will begin recovering any data that may have been lost. It is
recommended to instruct your subject to stay within, or return to, a 2-5 meter radius of the receiver
during this recovery process. If recovery is terminated (i.e. you select to cancel the recovery), it can still
be recovered later via offline data recovery.
7.3.2 Offline Data Recovery (Import Function)
Data can be recovered at a later point in time via the 'import' function within MR3. When you are ready
to recover data (offline) for one or multiple records, go to the Database tab within MR3. Then select
'import' from within the tools on the right side of the screen. The following options will be displayed:
