Channel (525Aplus, 720Aplus and 920Aplus only)
Press 2nd then channel (5) to change the electrode channel. On the
525Aplus and 720Aplus the channels are designated as CH-1 or CH-2. For
the 920Aplus, the channel designation appears before the electrode I.D., for
example,
1-pH or 2-F- . The instrument maintains separate calibration
curves for each channel.
Key 6 Slope
Press slope (6) to display the electrode slope in memory for the current
operating mode. After displaying the slope for a few seconds, the
isopotential point will be displayed. The meter then returns to its measure
mode. The Orion 920Aplus is the only meter that displays an isopotential
point in concentration mode. See Appendix E for information pertaining to
changing an isopotential point in concentration mode.
The prompt line identifies the slope or isopotential point along with the
electrode channel (525Aplus, 720Aplus and 920Aplus), and electrode I.D.
(920Aplus). Reviewing the slope and isopotential point is useful when
diagnosing measurement problems.
Electrode I.D. (920A only)
Press 2nd then electrode ID (6) to change the electrode identification on
the Orion 920Aplus. A series of numbered choices are presented. The user
types in the number of choice, then press
yes . Press no to scroll through
choices. This is a useful feature for keeping track of which electrode is
currently in use. It is particularly useful when using an electrode
switchbox.
Key 7 Print/Datalog
Press print /datalog(7) to print or datalog the current display data. Along
with the operating mode and results, the temperature, millivolt output, time,
and date are recorded. If the datalog function is turned off, only printing
will occur. Printing or datalogging on a keypress will occur even when
another print or datalog function is selected. Whenever printing or
datalogging is set to take place at a preset timed interval, the hold function
is automatically turned off.
mV
Press 2nd then mV (7), to display the current millivolt output of the
electrode without changing modes. This is useful if you want to check a
millivolt value during calibration or measurement. Press any key to return
to the previous function.
