Memory and Data
The WristOx
2
, Model 3150 measures, collects, and stores up to 1,080 hours 
of SpO
2
and pulse rate data with a 4-second data collection rate. Data collected at a 
1 or 2-second rate reduces memory capacity to 270 or 540 hours, respectively.
When the memory is full, the device overwrites the oldest existing data with the new data.
Each time the device is turned on, data are automatically stored in memory. Data collection
of less than 1 minute is not retained in memory.
Each time the device turns on, the current oximeter time and date (if the clock is set
properly) are stored in memory to allow quick differentiation of recording sessions. Patient
SpO
2
and pulse rate are stored every 4 seconds (default), or every 1 or 2 seconds if
programmed using nVISION software. The oxygen saturation values are stored in

1% increments in the range of 0 to 100%.
This device contains non-volatile memory. Removing or replacing batteries does not affect
the data stored in memory. Stored data remains in memory until overwritten by newer data
or cleared from memory with nVISION software.
NOTE: Downloading data in memory does not clear memory. To clear memory, see
“nVISION Settings.”
