CHAPTER

SETUP
The instructions in this chapter are for setting up a single CMRV-5000. For
additional information on multi-unit configurations, see APPENDIX D.
Physical placement
CAUTION The CMRV instrument is quite heavy. To avoid injury, obtain necessary
assistance when lifting and moving instrument components.
Placement Place the CMRV-5000 Controller/base unit on a stable laboratory bench
within 10 mm of the front edge. This orientation will allow the weight
suspended from the head unit pulley-wheel assembly to clear the edge of
the table during viscosity and yield stress tests. Place the head unit on top
of the Controller, and position the head unit so the rubber "feet" fit in the
corresponding holes in the top of the Controller chassis. Allow 30.5 cm
(12") of clearance to the back and sides of the units.
Thermometer placement When in use, the larger thermometer (-46°C to +30°C) is placed in the
thermometer well on the left side of the CMRV-5000 unit (seen from the
front).
When in use, the smaller thermometer (0°C to 105°C) is placed in the
thermometer well on the right side of the CMRV-5000 unit (as seen from the
front).
NOTE If the mercury column in a thermometer has separated during shipment,
read the instructions included in APPENDIX C. These instructions offer
several methods for joining separated mercury columns.
Electrical /serial connections
Attach the DC power cable to the OUTPUT connector on the Controller
and the INPUT connector on the head unit. Twist the connectors clock-
wise to secure the power cable connections.
Make sure the CMRV-5000 power switch on the Controller is in the OFF
position; then insert the power cable into the mating receptacle on the
Controller rear panel (see diagram, next page).
Thermistor
Insert the Lemo ® plug from the temperature probe into the jack marked
TEMP PROBE on rear of the CMRV Controller (see diagram, next
page). Apply a generous quantity of the supplied thermal paste to the
probe tip and insert the tip as far as it will go into the hole with the
rubber grommet on the right side of the CMRV-5000 head unit chassis
(as viewed from the front of the unit).
