Function
1
GPIB Connector
A GPIB controller can remotely control the Calorimeter by transferring signals
through this connector. The connector meets the requirements found in
IEEE-488 of 1978.
2
Coolant Drain
The coolant is removed through this drain. Refer to chapter 5 - Maintenance
for complete instructions on draining the coolant.
3
AC Power Receptacle
The ac power for operating the Calorimeter is connected through this recep-
tacle. It will accept a standard IEC 320 style female connector, such as the
one on the power cord supplied. The receptacle is filtered to reduce the pos-
sibility of EMI.
4
Fuse Drawer
The ac power line is fused to protect against short circuit fire and shock
hazards. The fuses are housed within the fuse drawer. Refer to chapter 5 -
Maintenance for complete instructions for replacing these fuses.
5
Main Power ON/OFF
Switch
The main power on/off switch turns ac power on and off to the Calorimeter
unit.
6
Address Dip Switch
The address dip switch sets the address code for the Calorimeter unit when
the unit is connected to a GPIB processor. The dip switch is set to
“10011000” (binary 24) when shipped from the factory.
Equipment Startup
Perform the following steps to start up the Calorimeter:
1. Depress the rear panel main power ON/OFF switch to the on position.
The front panel display will light for about four seconds and the pump
and fan will run. After initialization the display will indicate 0.0
watts; showing that the calorimeter is in power measurement mode.
+
Note: A false power level may be displayed if coolant has just been added or the
ambient room temperature has recently changed. If either happens, allow up to
30 minutes for the system temperature to stabilize.
2. Check the front panel display. If the ADD COOLANT annunciator is
lit, immediately shut off the power ON/OFF switch and add coolant
per instructions in chapter 5 - Maintenance.
