Ch a n g i n g Memo r y M odes
The DRI operates in three distinct memory modes:
• Single (on-demand memory)
• Continuous
• Standard
(
NOTE
: Main display reflects “nonE” in this mode)
To change the memory mode:
1. Press the PEAK button while holding down the ON button; the small display will reflect “dSP”.
2. Press the PEAK button six times; “Log” will appear on the small display and the main display will reflect the current setting.
3. Each time the > button is pressed, the main display will scroll through “SinG”, “Cont” and “nonE”.
4. Press the MEMO SET button to store the desired memory mode and exit.
NOTE
: Data stored in memory can be output to an external device (see “Communication with External Devices” section).
Single and Continuous Memory Modes
The three functions performed when using either the Single or Continuous mode are:
• Storing data
• Recalling data
• Deleting data
Storing Data (Single Memory Mode)
After selecting the “SinG” mode it is possible to send one data reading into memory each time the MEMO SET button is pressed; the
small display will briefly change to an “M”. The “M” indicates that the data reading displayed has been stored in memory. Up to one
hundred data readings can be stored. “FULL” will appear on the main display if memory is full.
Storing Data (Continuous Memory Mode)
After selecting the “Cont” mode it is possible to enter data readings continuously into memory by pressing the MEMO SET button once.
The small display will reflect a flashing “M” and data readings will be stored in memory as quickly as the display update rate chosen
(reference “Changing Display Update Time” section). Data readings will continually be entered into memory until the MEMO SET
button is pressed a second time or 100 samples have already been entered (“FULL” will appear briefly on the main display).
Recalling Data (Single and Continuous Memory Mode)
To recall data in the memory press the RECALL button; the last data reading entered and corresponding memory position will be flashing
opposite each other on the main display. Each subsequent push of the RECALL button will scroll through the data readings in the
opposite order as they were entered. Press the RESET button to exit from memory recall.
NOTE
: No data readings have been entered if “nonE” shows on the main display after pressing the RECALL button.
Deleting Data (Single and Continuous Memory Mode)
While recalling data (see above) it is possible to delete one data reading at a time or delete the entire memory.
To cancel one reading at a time:
Press the RECALL button to scroll through the data in memory until the undesired reading is appears on the display. Push the > button to
delete that data reading. All higher memory positions will decrement one to fill the deleted position. If the reading being deleted is the
last one in memory, then the memory position will decrement one as there is no higher memory position to take its place.
To delete the entire memory:
After recalling the memory using the RECALL button, press the RESET button while holding down the ON button; “CLr” will briefly
appear on the main display. This indicates that all data readings have been deleted and will automatically exit from memory recall.
