Myron L 3P - Manual (Page 8)

Single point Gain Calibration is complete. You may continue for
the 3rd point of Calibration (2nd Gain) or exit by pressing either
measurement key. Exiting causes the value accepted for the
buffer to be used for both acid and base measurements.
To continue with 3rd point calibration, use basic buffer if acidic
buffer was used in the 2nd point, or vice-versa. Again, match the
display to the known buffer value as in step 2 and continue with
the following steps.
7. Repeat steps 3 through 6 using opposite buffer solution.
8. Press to accept 3rd point of calibration which ends
Calibration Procedure. Replace protective cap.
2. ORP Calibration
ORP electrodes rarely give false readings without problems in the
reference electrode. For this reason, and because calibration solutions
for ORP are highly reactive and potentially hazardous, your Ultrameter
has an electronic ORP calibration. This causes the zero point on the
reference electrode to be set whenever pH 7 calibration is done.
3. Temperature Calibration
Temperature calibration is not necessary in the Ultrameter.
VI. MEMORY
This feature allows up to 20 readings with their temperatures to be stored
simultaneously for later recall.
A. Memory Storage
1. While displaying a measurement, press to record the
displayed value.
2. “ MEMORY ” will appear and
the temperature display will be
momentarily replaced by a
number (1-20) showing the
position of the record. Figure
4 shows a reading of 10.00 pH
stored in memory record #5.
B. Memory Recall
1. Press either measurement key.
2. Press , “ MEMORY ” will appear, and the display will show
the last record stored.
3. Press the or to scroll to the record location desired
(the temperature display alternates between temperature
recorded and location number).
4. Press a measurement key to leave memory recall or allow to
automatically turn off.
C. Clearing a Record/Memory Clear
After recalling a certain record location, press
to clear that
memory. This space will be the place for the next memory record,
unless you scroll to another position before ending the recall
sequence. The next memory stored will go into the next highest
available memory location.
Example: You have locations 1-7 filled. You want to clear the ORP
reading stored in record location # 3 and replace it with a pH reading.
1. Press and scroll to location # 3 .
2. Press to clear old record # 3 .
3. Fill pH/ORP sensor well with sample.
4. Press to measure sample and press to store
reading in location # 3 .
5. The next memory stored will go into location # 8 .
6. To clear all records: After
pressing , scroll down
to “ CL r ALL ” in measurement
and temperature area
(see Figure 5).
7. Press . All records will be cleared.
