WARNING: High voltage, current, and RF power are present in the system at various times throughout this procedure. This procedure should only be performed by qualified personnel sufficiently trained in the safe operation of high voltage, current, and RF power systems. Failure to follow these precautions may result in death or bodily injury, or equipment damage.

SYSTEM INSTALLATION

Instrument Connections

WARNING: High voltage and current are present on the system. Install proper safety equipment (e.g., fuses, breakers, etc.) as necessary between the AC Power Source and Voltage/Current RF Adapter. Failure to install adequate safety equipment may result in death or bodily injury, or equipment damage.

1. Connect the Voltage/Current RF Adapter through an appropriately sized fuse or breaker to the AC Power Source. See Figure 1 below. WARNING: Dangerous voltage, current, and RF power may be present on the system. Users should install interlock devices as appropriate for safe operation.

2. Connect interlocks (user-supplied) to the Calorimeter and system as necessary.

3. Connect the Calorimeter and Power Analyzer ethernet ports to the network.

4. Connect the AC Power Source to the network using the ethernet port or the RS-232 serial connection. Ethernet is preferred.

5. Connect the thermocouple from the Calorimeter to the 12 kW Chiller as shown in Figure 2.
   WARNING: Comply with all local codes and regulations for installation of all instrumentation. Follow guidelines in supplier manuals for connections to AC Power Source and 12 kW Chiller. Failure to install equipment properly may result in death or bodily injury, or equipment damage.

6. Connect AC mains power to the Calorimeter, AC Power Source, 12 kW Chiller, and Power Analyzer. The Power Analyzer and Calorimeter are powered from separate 200-240 VAC outlets. The Calorimeter requires a 20A service.

Chiller Preparation

1. Fill the 1 kW Chiller coolant reservoir, located at the top of the system rack cabinet (see Figure 3 below), 4 cm (15/8 inches) above the return inlet with a coolant mixture of 25% SR-1 antifreeze to 75% distilled water.

2. Power ON the Calorimeter and the 1 kW Chiller. Once the Calorimeter completes the boot process:

   • a. On the Calorimeter front panel, press the SETUP softkey.
   • b. Navigate to Instrument using the arrow keys and press ENTER.
   • c. Navigate to PUMP and press ENTER.
   • d. Navigate to USE PUMP and press ENTER.
   • e. Press ENTER again to begin editing the parameter value.
   • f. Press the UP arrow key to change the parameter value to TRUE and press ENTER.

3. Allow sufficient time for the coolant to circulate through the system before proceeding to the next step.
   NOTE: The coolant level may drop as coolant fills the system hoses, Calorimeter, and 1 kW Chiller. If necessary, add additional coolant mixture as necessary to the 1 kW Chiller reservoir to bring the coolant level back to 4 cm above the return inlet.

4. Power OFF the 1 kW Chiller.

5. Power OFF the Calorimeter and chiller pump using the system rack power switch.

6. Connect the supply and return hoses between the 12 kW Chiller and the system rack cabinet as shown in Figure 4.

7. Fill the 12 kW Chiller coolant reservoir using about 50 liters (13.2 gallons) of a 25% SR-1 antifreeze and 75% distilled water mixture.

8. Power ON the 12 kW Chiller.

9. On the 12 kW Chiller display, touch the PUMP ONLY icon and hold for 2-3 seconds to circulate coolant.

10. Allow sufficient time for the coolant to circulate through the system before proceeding to the next step.
    NOTE: If the coolant level drops and triggers a low coolant alarm, add additional coolant mixture as necessary to the 12 kW Chiller reservoir until the alarm turns off. Clear the alarm on the 12 kW Chiller display.

11. On the 12 kW Chiller display, touch the PUMP ONLY icon and hold for 2-3 seconds to stop flow circulation coolant.

12. Power OFF the 12 kW Chiller.

Note that the information will appear in various HPC-CAL calibration software output files.
    Field| Description
    ---|---
    ID| Technician ID or initials.
    Procedure| The calibration authority/procedure for the test.
    Report Number| The report number must be 10 characters and should be unique. The date, including minutes (yymmddhhmm), is recommended to ensure each report number is unique.

Table 1: Step 1 group field definitions

14. In the Calorimeter Check group, verify the Calorimeter Flow: and Flow Meter: fields indicate 4.05 GPM ±0.03, and that Coolant Temp: indicates 22.1 °C ±0.4 (see Figure 11, Step 1 below).
15. (Optional) In the Step 2 group, click to select the Check power to standard check box (Figure 11, Step 2).This setting instructs the HPC-CAL calibration software to verify the connection between the Power Analyzer and AC Power Source.
16. In the Step 2 group, click the Check All Equipment button (Figure 11, Step 3).
17. Wait approximately 60 seconds for the HPC-CAL calibration software to verify communication with the connected instruments. Verify the Power Source, Power Standard, and Calorimeter checkboxes are checked. The Check All Equipment button text should be black (Figure 11, Step 4).
18. In the Step 3 group, click the Start Auto Test button (Figure 11, Step 5).
19. In the dialog box, verify that the test power level, and Calorimeter serial and model numbers are correct.
20. Click OK to dismiss the dialog box and begin the automated calibration.
21. The HPC-CAL calibration software will save a calibration data file in the current user’s Documents directory at the completion of the test.

Data Analysis
NOTE: In rare cases, pop-ups may appear announcing that the measurement settling criteria have not been met. If this happens, evaluate the warning and obtain Engineering approval to continue test or abort test. Failure to meet settling criteria could be a sign of an equipment malfunction, and each such failure should be analyzed. Repeated failure on one step may indicate that the criteria is too tight, or the settling time is too short. In either of those cases, the test definition can be changed consistent with quality requirements.

1. Navigate to the current user’s Documents directory (%userprofile%\documents).
2. Locate and open the data file from the calibration completed in the previous steps. The filename will be HPC-CALTest_yyyy_MM_dd_HH_mm_ss.log (yyyy = four-digit year, MM = month, dd = day of month, HH = 24-hour clock hour, mm = minutes, ss = seconds). The date/time portion of the file name corresponds to the time the calibration finished.
3. If required for reporting or auditing purposes, copy the data file to an appropriate location.

Alignment

1. In the HPC-CAL calibration software, click the Calorimeter tab (see Figure 12 below).

2. Click Create Cal. File and Save to create a new calibration file based on the calibration data collected in Step 3.2. Calibration above (Figure 12).

3. In the dialog box, save the new calibration file in appropriate location. The file name must be Calibration.ini as the Calorimeter will not read a calibration file with any other name.
   NOTE: It is recommended to store the calibration file in its own directory, and name the directory using the current date and other descriptive information as necessary. The directory should contain no other calibration.ini files. Save the file as “Calibration.ini” and not as any other name. The calorimeter will not use files with a different name.

4. Click Send Cal. File and Restart (Figure 12).

5. In the dialog box, pick the calibration file saved in Step 3 above.

6. Click OK to load the calibration file.

7. The Calorimeter will restart after loading the calibration file. The alignment is complete when the Calorimeter restarts and completes the boot process.
