1Preface
1.1 Scope
The MSR rotator is a solid-state-controlled servo-system designed to rotate an
electrode in an electrochemical cell. This manual describes the proper use of the
MSR rotator and covers routine operating procedures, periodic maintenance and
calibration, and safety issues.
The reader of this manual is assumed to have some basic knowledge of
electronics, electrochemistry, and the modern practice of voltammetry. While
some background information is presented in this manual, the reader is referred
to the appropriate scientific literature for more detail regarding the theory and
practice of hydrodynamic voltammetry.
Pine Research Instrumentation provides online support for the rotator at the

LIMITED WARRANTY
The Pine MSR Rotator (Pine part number AFMSRCE, hereafter referred to as “WARRANTED
INSTRUMENT”) offered by Pine Research Instrumentation, Inc. (hereafter referred to as “SUPPLIER”) is
warranted to be free from defects in material and workmanship for a one (1) year period from the

to have been defective. The CUSTOMER may be obligated to assist SUPPLIER personnel in servicing
the WARRANTED INSTRUMENT. SUPPLIER will provide remote support (via telephone or internet) to
guide the CUSTOMER to diagnose and effect any needed repairs. In the event that remote support
is unsuccessful in resolving the defect, SUPPLIER may recommend that the WARRANTED INSTRUMENT
be returned to SUPPLIER for repair. This warranty is expressly in lieu of all other warranties, expressed or

DRU10002 (REV 004 / JAN 2017)
1.6 Instrument Markings
Labels on the control unit and motor unit bear information to identify the MSR
rotator and to indicate any certifications or independent testing agency marks
which pertain to the instrument (see Figure 2.4).
1.6.1 Certifications and Listings
The MSR rotator complies with one or more EU directives and bears the CE
marking. See the "CE Declaration of Conformity" attached to the end of this
manual for more details.
The MSR rotator is listed by Intertek to UL 61010-1 (issued 11-MAY-2012; Ed. 3),
CSA C22.2 #61010-1 (issued 11-MAY-2012; Ed. 3), and IEC 61010-1 (issued 10-
JUN-2010; Corrigendum 1: 11-MAY-2011). Intertek is a Nationally Recognized
Testing Laboratory (NRTL) recognized by the United States Occupational Safety
and Health Administration (OSHA).
1.6.2 Serial Number
For purposes of uniquely identifying a particular instrument, there is a label on the
back panel of the control unit which indicates the model number and the serial
number. A matching serial number is also found on a similar label located on the
motor unit. In laboratories with multiple MSR rotators, it is important to keep the
control unit together with the matching motor unit because the two components
are calibrated together as a system (see Section 6.6).
1.6.3 Model Numbers
Pine MSR rotator model numbers have the format 'AFMSRWXYZ' where W, X, Yand
Z are each single characters used to indicate the particular configuration of the
rotator (see Table 1.1). The final characters (X, Yand Z) may be blank. Part
numbers for electrodes and other accessories compatible with the MSR rotator
are described in more detail later (see Section 5 and Section 7).

Consultez la documentation pour l’électrode spécifique à utiliser pour connaître
la vitesse de rotation maximum de l’électrode.
CAUTION:
Always turn the rotation rate control knob completely
counterclockwise (towards the zero rotation rate position) before
turning on the rotator.
ATTENTION:
Tournez toujours le bouton de commande de la vitesse de rotation
complètement dans le sens inverse des aiguilles d’une montre (vers la position
vitesse de rotation égale à zéro) avant de mettre le rotateur en marche.
WARNING:
Rotating shaft. Entanglement hazard.
Turn off the power to the rotator and disconnect the power cord
from the power source before installing or removing the electrode
shaft or before installing or removing an electrode tip on the end of
the shaft.
AVERTISSEMENT:
Arbre en rotation. Danger d’enchevêtrement.
Éteignez le rotateur et débranchez le cordon d’alimentation de la source
d’alimentation avant d’installer ou d’enlever l’arbre de l’électrode ou avant
d’installer ou d’enlever un embout d’électrode à l’extrémité de l’arbre.

11
DRU10002 (REV 004 / JAN 2017)

tilt away from the axis of rotation while rotating. Such a shaft is
either improperly installed or physically damaged. Turn off the
rotator, disconnect electrical power, and remove the shaft
immediately.
AVERTISSEMENT:
N’utilisez pas un arbre d’électrode qui semble osciller, vibrer ou dévier de l’axe

CAUTION:
When raising or lowering the motor unit along the main support rod,
be sure to hold the motor unit carefully so that it does not
unexpectedly fall and break the glass cell located below the motor
unit.
ATTENTION:
Lorsque vous montez ou descendez le bloc moteur le long de la barre principale,
veillez à bien le tenir pour éviter qu’il ne chute brutalement et ne casse la cellule
de verre située sous le bloc moteur.
CAUTION:
A detachable main power cord is provided with the rotator. Do not
