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.
7. Temperature Calibration
Temperature calibration is not necessary in the Ultrameter.
VII.
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
9 shows a reading of 1806 µS
stored in memory record #4.
B. Memory Recall
1.
Press one of the five measurement keys.
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 any 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 conductivity
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 10).
7.
Press . All records will be cleared.
VIII.
CHANGING from CENTIGRADE to FAHRENHEIT
1.
Press .
2.
Press to display the stored memory records.
3.
Press repeatedly until you pass the memory “
CL
r
ALL
”
location. The display will show a “
C
” or “
F
”
(see Figures 11 & 12).
