Hello rbs, welcome to the community!
We follow the standard channel naming that is described here:
IRIS: SEED Channel Naming and here IRIS: SEED Channel Naming
In your case:
- SHZ = vertical acquisition channel, 50 sps (samples per second)
- EHE = east-west acquisition channel, 100 sps
- EHN = north-easth acquisition channel, 100 sps
- EHZ = vertical acquisition channel, 100 sps
With location, do you mean the floor of the building the device is on, or the geographical location?
If the first is true, then we recommend (if possible) to put the Shake on the lowest floor of the building, away from any vibrating machinery. If you meant the second instead, the elevation is important for the location algorithm to work properly, but is already taken into account with the latitude and longitude data that have been input.
