Using the Universal Power Adapter
A universal power adapter (Catalog Number 1010003) with US, EU, UK and China plug plates
is included with the Orion Dual Star pH/ISE benchtop meters. This universal power adapter is
specifically for use with Orion Dual Star benchtop meters. Use of other power adapters can
damage the meter and void the warranty.
1. Select the appropriate plug plate for the power outlet that will be used.
2. Remove the clear plastic cover from the groove on the back of the power adapter.
3. Slide the appropriate plug plate into the groove on the back of the power adapter.
4. Connect the assembled power adapter to a power outlet and the meter input labeled
Power. A surge protector or uninterrupted power supply (UPS) is also recommended.

Attaching the Electrode Stand and Holder
Redesigned Orion Dual Star meters are compatible with the meter-attachable electrode stand
(Cat. No. STARA-BEA) shown below. The electrode stand can be attached to either side of the
meter and up to two stands can be attached to each meter. A weighted base (Catalog Number
STARA-HB) is also available to support the stand without attachment to the meter. Older style
Orion Dual Star meters can be used with this electrode stand, but require additional purchase of
the weighted base (Catalog Number STARA-HB).
1. Open the box containing the electrode stand. The box will include a base plate, electrode
arm, pivot pin, electrode holder, ATC spacer and RDO clip.
2. Turn the meter over, with the meter display facing down, on a clean dry surface.
3. Identify the side of the meter that the stand will be installed on and remove the screw
between the circles on that side of the meter.
4. Align the base plate of the stand with the circles on the meter.
5. Replace the screw from step 3 to attach the base plate to the meter.
6. Turn the meter over, with the meter display facing up.
7. Insert the electrode arm into the metal post on
the base plate.
8. Connect the electrode holder to
the electrode arm using the pivot
pin.

Using the Electrode Holder
Place electrodes in the stand for easy movement in and out of containers during calibration,
sample measurement and storage. Recommended electrode positions are shown below.
Powering the Meter On and Off
1. If the meter is not connected to a wall outlet via the universal power adapter, select the
appropriate wall outlet plug and slide the plug plate it into the groove on the power
adapter. Connect the power adapter to the meter and wall outlet.
2. Press and hold the power key for about three seconds to turn on the meter.
3. When the meter is on, press and release the power key to turn the display backlight off or
to vary the intensity of the backlight. There are five levels of intensity that the power key
can be used to select.
4. To turn off the meter, press and hold the power key for about three seconds, until the
meter display is blank.
Meter Maintenance
For routine meter maintenance, dust and wipe the meter with a damp cloth. If necessary, warm
water or a mild water-based detergent can be used. Meter maintenance can be performed on a
daily, weekly or monthly basis, as required by the environment in which the meter is operated.
Immediately remove any spilled substance from the meter using the proper cleaning procedure
for the type of spill.
