Rack Mounting
The model 6091P Calorimeter is ready for installation into a 19-inch, type 4U elec-
tronics equipment rack. The model 6091 can also be rack mounted. To rack mount
the 6091, unscrew the four front panel screws and remove the unit from the instru-
ment case (Store the case for future use).
The ON/OFF switch and power cord connector on the rear panel may not be accessi-
ble once the unit is installed in the rack. Connect the power cord (at the back of the
unit only) and place the ON/OFF switch in the ON position before installing the Calo-
rimeter in the rack.
CAUTION
The rack enclosure must provide at least 100 ft
3
/min of unrestricted air flow. Avoid
mounting the Calorimeter above instruments that give off heat. If necessary, isolate the
Calorimeter from heat-generating devices with foam or fiberglass.
Install the Calorimeter in the equipment rack as follows:
1. Carefully slide the Calorimeter into the rack opening.
2. Fasten the front panel in place with four 1/4-20 pan head screws.
3. If possible, attach vertical support brackets to the rear panel of the
Calorimeter.
Connecting GPIB Cables
The Calorimeter and up to 14 other measurement devices can be connected to one
GPIB controller.
CAUTION
The total length of all cables used must be less than the number of devices connected times
2 meters (6.6 feet). Never exceed 20 meters of total length.
CAUTION
Only finger-tighten the GPIB connector screws. The screwdriver slots are provided for
loosening and removal of screws only. Connector screw threads may be stripped if
tightened with a screwdriver.
+
Note: GPIB cables mount one on top of the other. This allows the connection of
several instruments in a “daisy chain”.
Use the GPIB cable supplied to connect the Calorimeter and GPIB controller as
shown in figure 6. Press the mating connectors together firmly. Secure the connectors
with the screws provided.
