2. Use a small flathead screwdriver to gently pry the fuse drawer out of the
power entry module.
3. Slide the voltage selector card out of the fuse drawer. Reinsert the card so that
the correct line voltage appears in the window.
4. Check the current rating of the fuses with requirements in table 2. Install the
correctly rated fuses in the fuse drawer.
5. Re-install the fuse drawer in the power entry module.
AC Power
Connection
An ac power cord is supplied with the Calorimeter unit. The female end of the power
cord plugs into the power entry module, refer to figure 5.
The male end of the power cord is equipped with a U.S. standard NEMA 5-15,
three-pronged connector for mating with a grounded 120-volt wall receptacle. You
must purchase the appropriate cord for connection to any other receptacle.
Make ac power connections as follows:
1. Locate the power ON/OFF switch on the rear panel of the unit. Place the
switch in the OFF position.
2. Check the input voltage rating indicated on the power entry module. Verify
that the voltage indicated matches the supply voltage for your installation. If
not, change the voltage selector switch per the Setting the Voltage Selector
Switch section.
3. Plug the female end of the power cord into the power entry module.
4. Plug the male end of the power cord into a mating three-pronged receptacle.
Filling the Coolant
Reservoir
The Calorimeter requires 525 ml (10 fl oz) of coolant (Bird P/N 6091-120). The coolant
reservoir is emptied prior to shipment or extended storage. Refer to figure 6 and fill
the coolant reservoir as follows:
WARNING
Coolant containing ethylene glycol is a potential health hazard. Avoid ingestion, inhaling of
vapors and eye and skin contact.
CAUTION
Use only premixed coolant Bird part number 6091-120. Use of other solutions will damage
the instrument and void all warranties.
CAUTION
The Calorimeter can overheat if operated without sufficient coolant. Failure to keep coolant
reservoir adequately filled can result in serious damage to the equipment.
CAUTION
Do not apply RF power to the load without proper coolant flow. Failure to keep coolant at
proper flow rate can result in serious damage to the equipment.
