YSI, Incorporated Model 85 21
SECTION 8 SAVING DATA
The Model 85 is equipped with non-volatile memory that is capable of storing up to 50 different sets
of readings. Non-volatile means that you do not need to worry that your data will be lost due to a
power failure or power interrupt. The Model 85 will also assign a site identity number to each set of
readings to allow easy review of the data. This feature is useful in situations where transcribing data
is difficult or not available.
8.1 SAVING DATA TO MEMORY
1. While any parameter is displayed on the screen depress the ENTER button and hold for
approximately 2 seconds. The meter will flash SAVE on the display along with the current site
identity being used.
2. When all 50 sites are full the display will flash FULL on the screen. This message will remain on
the screen (even after power down) until a button is pushed.
Once you have acknowledged the memory is full, any subsequent saved data will begin overwriting
existing data starting with site #1.
8.2 RECALLING STORED DATA
1. To put the Model 85 into the RECALL mode depress the MODE button repeatedly until rcl is
displayed on the screen along with the site ID number in the lower right corner. (see figure #1)
2. Depress the ENTER button to review the last set
of data that was saved. The Model 85 will display the
dissolved oxygen in % saturation and temperature.
Another press of the ENTER button will display the
dissolved oxygen in mg/L and the temperature.
Depress the ENTER button again and again to
review the conductivity, specific conductivity and
salinity readings. All of which are displayed with the
temperature.
