Thermo Scientific Orion Versa Star User manual

Versa star RDO/Dissolved Oxygen Temperature Module
Thermo Scientific Orion
Instruction Sheet
This literature provides basic instructions on operating the Thermo Scientific™Orion™Versa star™meter when the
Versa star RDO/DO measurement module is installed. For comprehensive information on meter and module system
setup, operation and advanced features, please refer to the Versa star user manual available on the Versa star
literature CD or www.thermoscientific.com/water.
Preparation
1. Prepare the universal power adapter, install the meter-attached
electrode stand and verify that the RDO/DO module is connected to
the meter. If it is not connected, insert the module into an available
channel on the back of the meter.
2. Select either the Thermo Scientific™Orion™RDO™optical DO
probe or Orion polarographic DO probe, based on sample range and
requirements. Prepare the electrodes as instructed in the electrode
user manuals. For improved movement and control, place the
electrodes into the electrode stand.
3. Connect the dissolved oxygen probe cable to the 9 pin MiniDIN input on the module.

Data Log
Versa star meters offer a 2000 point data log. Each point
includes measurements from one to four channels with
the date and time. When the data log function is turned
on in the Instrument Settings setup menu, the read type
determines how the displayed measurements are saved
to the data log.
1. In the measurement mode, press the setup key.
2. Press the or key to highlight Log View and press
the f3 (Select) key.
3. Press the or key to highlight Data Log.
4. Press the or key to highlight View and press the
f3 (Select) key.
5. Press the or key to highlight a point and press the
enter key to view detailed data for that point. Press the
or key to scroll through additional data log points.
6. Press the measure (esc) key to return to the
measurement mode.
Calibration Log
The calibration log contains up to the ten most recent
calibrations per pH, RmV, ORP, ISE, incremental
technique, conductivity, DO and RDO parameter.
1. In the measurement mode, press the setup key.
2. Press the or key to highlight Log View and press
the f3 (Select) key.
3. Press the or key to highlight Cal Log.
4. Press the or key to highlight the desired
calibration parameter and press the f3 (Select) key.
5. Press the or key to view each calibration for the
selected parameter.
6. Press the measure (esc) key to return to the
measurement mode.

Measurement
The read type selected for each channel will determine
how measurements are displayed and saved (data log
must be on in the Instrument Settings setup menu).
Auto-Read – Press the measure (esc) key to start a
measurement. When the measurement is stable, the
AR icon will stop flashing and the measurement will be
locked on the display and saved to the data log. Press the
measure (esc) key to take a new measurement.
Timed – Measurements are continuously updated on
the display and saved to the data log at the pre-set time
interval until the measurement mode is exited.
Single-Shot – Press the measure (esc) key to start a
measurement. When the pre-set wait time is reached,
the measurement is locked on the display and saved to
the data log. Press the measure (esc) key to take a new
measurement.
Continuous – Measurements are continuously updated
on the display. Press the log/print key to save the
measurement to the data log.
Press the channel key until the desired combination of
measurement channels are shown.
1. Rinse the electrodes with distilled water or appropriate
solution, blot dry with a lint-free tissue and place into
the sample.
2. Start the measurement and wait for the reading to
stabilize or reach the set time.
a. When using the Auto-Read or Single-Shot read
type, press the measure (esc) key to start the
measurement and stirrer probe.
b. When using the Timed or Continuous read type,
measurements will start immediately; press the
stirrer key to start and stop the stirrer probe.
3. Once the measurement is stable or reaches the set
time, record all applicable parameters.
4. Remove the electrodes from the sample, rinse, dry and
place into the next sample.
5. Repeat steps 2 through 4 for all samples. When all
samples have been measured, store the electrodes as
instructed in the electrode user manuals.

Single Channel Display
Customizing the Display
Select the information shown in the measurement mode.
1. In the measurement mode, press the setup key.
2. Press the key until Instrument Settings is highlighted
and press the f3 (Select) key.
3. Display will be highlighted in the left column. Press the
key to also highlight Display View and press the f3
(Select) key.
4. Press the or key to highlight an item and press
the f3 (Select) key to check (display) or uncheck (hide).
5. Press the f1 (Done) key. Press the measure (esc) key
to return to the measurement mode.
4. If using the Thermo Scientific™Orion™Star™stirrer
probe, attach the stirrer probe cable to the STIRRER 1
input (default input for channels 3 & 4) or STIRRER 2
input (default input for channels 1 & 2) on the meter.
5. Set up the work area with calibration equipment, rinse
water, samples and other supplies.
6. If applicable, connect the meter to an external device
using the appropriate cable. A USB cable is included
with the meter for computer interfacing.

Default values are in bold. For automatic pressure
compensation of dissolved oxygen measurements, the
meter-integrated barometer is used. For automatic
salinity correction of dissolved oxygen measurements,
install conductivity and RDO/DO modules on the meter,
prepare a conductivity probe and DO probe, and
ensure both probes are in the same sample during
measurement.
