Key 9 Set Temp
Press set temp (9) to access the set temp function to manually set the
temperature. This is used for manual temperature compensation in pH
mode and in concentration mode on the Orion 920Aplus. If a temperature
probe is in use, the meter will not allow a temperature to be set manually.
If no temperature probe is in use, the main display will show 25.0 DEG and
the prompt line will show ENTER VALUE. Use the numeric keys to enter
the temperature of your solution, then press yes. The meter verifies your
entry, then returns to measure mode. See temperature compensation section
for more information on temperature.
Ready
Press 2nd then ready to access the ready function, which identifies when
the electrode signal is stable. The ready signal may be turned on or off. The
prompt line verifies your selection then returns to measure mode. Example:
READY OFF.
The ready function is tied to the resolution selected. The less resolution
selected the faster the ready signal will be displayed.
The ready signal appears in the prompt line as READY (520Aplus) or
RDY (525Aplus, 720Aplus or 920Aplus).
