Viewing the Calibration Log and Data Log
Viewing the Calibration Log
The Orion Dual Star meter saves up to ten of the most recent calibrations on each channel.
Each of the ten calibrations per channel is saved according to the calibration type (pH, ISE,
RmV or ORP), so the meter will use the last calibration performed for the calibration type (as
long as it is one of the last ten most recent calibrations) and pH, ISE, RmV and ORP electrodes
can be interchanged without recalibrating every time the electrodes are switched.
For example: 1. The channel one measurement mode is set to pH, a pH electrode is connected
to the channel one input and a pH calibration is performed. 2. The channel one measurement
mode is set to ORP, an ORP electrode is connected to the channel one input, an ORP
calibration is performed. 3. The channel one measurement mode is set back to pH and the pH
electrode is reconnected to the channel one input. In this scenario, the meter will use the pH
calibration performed in step 1 for the pH measurements displayed after step 3.
1. In the measurement mode, press the log view key.
2. Press the ▲ / ▼ keys to highlight Calibration Log and press the f2 (accept) key.
3. Press the ▲ / ▼ keys to highlight Channel 1 Cal or Channel 2 Cal and press the f2 (select)
key.
4. Press the ▲ / ▼ keys to highlight pH, ISE, RmV, ORP or Temperature as the calibration
type and press the f2 (select) key.
5. The meter will display a list of calibrations for the selected channel and calibration type. The
list shows the sequential number of the calibration (Cal_101), the date that the point was
saved (07/05/2008) and the time that the point was saved (12:05).
6. To view the calibration data, press the ▲ / ▼ keys to highlight the calibration point and
press the f2 (select) key. Press the f2 (print) key to print the calibration point, press the
f3 (graph) key to view the calibration graph or press the f1 (back) key to return to the list of
calibration points.
7. Press the f1 (back) key twice to return to the measurement mode.
Viewing the Data Log
The Orion Dual Star meter saves up to 1000 points of data and assigns a log number to each
data point. The read type of the displayed channel or channels determines when
measurements are exported to the data log. When the meter is in the dual channel display
mode, the measurements from both channels will be saved as two separate data points. When
a data point is exported to a computer or printer, the time stamp will include the hour, minutes
and seconds.

1. In the measurement mode, press the log view key.
2. Press the ▲ / ▼ keys to highlight Data Log and press the f2 (accept) key. The meter will
display a list of the data points. The list shows the sequential number of the data point
(D0001), the date that the data point was saved (07/05/2008) and the time that the data
point was saved (14:05).
3. To view the measurement information for an individual data point, press the ▲ / ▼ keys to
highlight the data point and press the f2 (select) key. Press the f2 (print) key to print the data
point or press the f1 (back) key to return to the list of data points.
4. To export the data log to a computer or printer, press the f3 (options) key, press the ▲ / ▼
keys to highlight Log Export and press the f2 (accept) key. Press the ▲ / ▼ keys to
highlight Today, Last 10, Range or All as the data log points to be exported and press the
f2 (accept) key.
a. If Today, Last 10 or All is selected, press the f2 (yes) key to export the data. After
exporting the data, the meter will automatically return to the measurement mode.
b. If Range is selected, use the numeric keypad to enter the number of the first data point
to be exported, press the f2 (accept) key, use the numeric keypad to enter the number
of the last data point to be exported, press the log/print key and press the f2 (yes) key
to export the data. After exporting the data, the meter will automatically return to the
measurement mode.
c. To clear the data log, press the f3 (options) key, press the ▲ / ▼ keys to highlight Log
Clear and press the f2 (accept) key. Press the f2 (yes) key to clear the entire data log.
Enter the password using the alphanumeric keypad and press the f2 (accept) key. The
default password is 111111111. Press the f1 (back) key to return to the list of data
points.
5. Press the f1 (back) key twice to return to the measurement mode.

Interfacing a Printer
The Orion Star series printer, Cat. No. 1010006, is recommended for use with the Orion Dual
Star meter. The Orion Star series printer has a 9600 baud rate and it is packaged with the
RS232 printer cable, Cat. No. 250302-001, which is required to interface the Orion Dual Star
meter to a printer. The Orion Star printer is also designed to print the calibration graphs and will
show the data in the graph clearly with the best picture and detail. Other printers may print the
calibration graphs as a bunch of information that looks like random text and numbers; however,
the raw calibration data should print fine.
The baud rate of the Orion Dual Star meter can be set to 1200, 2400, 4800, 9600, 19200 or
38400 for communication to different printers. The fixed meter settings are number of bits = 8,
stop bits = 1 and parity = none. The flow control for the printer should be set to XON/XOFF.
The meter will send measurements and calibration data to the printer if the printer option is
turned on in the setup menu. Alternatively, measurements and calibration data can be sent to
the data log and calibration log. From the data log and calibration log, the operator can chose to
print a single data log point, a range of data log points or the entire data log.
Interfacing a Computer
The Orion Dual Star meter can send measurements and calibration data to a computer in a
comma delimited format that is easy to parse in computer programs like Microsoft
®
Excel
®
.
Connect the USB computer cable to the USB inputs on the meter and computer and install the
Dual Star USB driver, downloadable on our website at
www.thermoscientific.com/OrionMeters
.
Alternatively, connect the RS232 computer cable, Catalog Number 1010053, to the RS232
inputs on the meter and computer.
The baud rate of the Orion Dual Star meter can be set to 1200, 2400, 4800, 9600, 19200 or
38400. The fixed meter settings are number of bits = 8, stop bits = 1 and parity = none. The
flow control for the computer should be set to XON/XOFF.
The meter will send measurements and calibration data to the computer if the computer option

the data log and calibration log. From the data log and calibration log, the operator can chose to
