Page 10: Product Overview
Figure 2: Model 1314 250W Precision Calorimeter (in optional rack w/PC) The model 1314 is a precision calorimeter that can provide highly accurate RF power measurements up to 250 W in the 50 Hz to 3 GHz frequency range, and is traceable to the... - Page 11 The 1314 block diagram is shown in Figure 2. To begin, RF energy is converted to heat energy inside a RF load containing a circulating coolant flow. The heat energy is dissipated in the coolant, carrying this heat away in the coolant.

CAUTION: Use only pure distilled water in the coolant mix. Do not fill the unit with de-ionized water, flammable fluids, corrosive fluids, explosive, or any other hazardous fluids. 1. Disconnect the main power cord! 250W Precision Calorimeter 1314-900 Revision BA... -
Page 15: Establish Communication With The 1314
The cap is unvented, so you can locate the unit either above or below the load. Establish Communication with the 1314 1. Connect the 1314 ethernet port into a network hub on the same network as the computer. Note: The TEGAM Program Iguana Manager can be used to upload all updated system initialization files to the 1314 through these communication interfaces (cables) if the system is not intended to be setup for automated measurements. - Page 16 Figure 7: Front Panel 3. Turn on the 1314 by pressing the power button located in the lower left front panel area of the unit. It takes a minute or so for the unit to fully power up, so patience is needed.

Page 17: Connect The Chiller And Prime The Coolant Pump
The unit is now ready to prime the pump and the proper flowrate will be adjusted to a value of .5 to .55 GPM using the flow adjust knob on the rear of the 1314 unit as... - Page 18 6. When the pump is properly primed the orange light will be illuminated on the right side of the chiller display [PUMP SET]. Figure 10: Display indicating properly primed pump 250W Precision Calorimeter 1314-900 Revision BA...
- Page 19 9. When the bubbles disappear the pump should be fully primed. The displayed flow valve from the Iguana Manager program should now display a value around .5 GPM. If not, adjust the flow adjust knob located in Figure 12 until 0.5 to 0.55 GPM is established. 250W Precision Calorimeter 1314-900 Revision BA...

Page 20: Adjusting Coolant Flow
Use the adjusting knob to set flow rate. The displayed flow rate will not change quickly due to the filtering taking place inside the 1314 but an increase or decrease can easily be detected when adjusting the knob. It typically takes about 30 minutes for the flow rate to reach a steady state value, so patience is needed here. -
Page 21: Adjusting The Set Point Temperature
In a typical case the set point is set to 20 degrees C when the normal lab ambient is 23 C.
