Programming Features
Memory can be configured in slate or wrap mode.
Note: When slate memory mode is used and becomes full, the 950 will enter program complete
mode and stop logging data.
Slate Memory Mode —Slate mode causes logging to stop when memory becomes full.
The flow meter continues to operate but no more data is logged. Use this mode so no
data is lost from the beginning of the logging period.
Wrap Memory Mode —In wrap mode, when memory becomes full, the oldest reading is
discarded each time a new reading is taken. When memory becomes full, the flow meter
continues to operate and log data. This mode is best used to receive the most recent
data readings.
