Maintenance Procedures
Note: During the calibration process the last read pressure and gas temp will be used (LCD shows “- - CAL- -“) to calculate
Corrected volumes, therefore it’s recommended to get into the calibration mode BEFORE removing the live pressure (or live gas
temp) so the profiler will not record the pressure drop of removing the live pressure or removing the live temp from the gas line.
Pressure Calibration:
Note: Before removing pressure from the HDR follow these steps below:
1. Using HDR Host, go to the “Calibrate” column/ select “Calibration Wizard”.
2. The HDR will lock in the last read pressure until the calibration is complete.
3. Now connect a pressure gauge or dead weight tester.
4. Select “Two Point Gas Pressure Calibration”.
5. Click “Begin”.
6. Apply 20% of full scale pressure measured with standard reference gauge or deadweight.
7. Click “Next”.
8. Wait 10 seconds to get a stable reading and click “Next”.
9. Enter Pressure reading indicated by standard gauge and click “Next”.
10. Apply 80% of full scale pressure measured with standard reference gauge or deadweight.
11. Click “Next”.
12. Wait 10 seconds to get a stable reading and click “Next”.
13. Enter Pressure reading indicated by standard gauge.
14. Click “Next”.
15. At the calibration comparison screen, click “Done”.
16.
Click “Save” button to save the calibration.
17. Then click the “Finished” button.
18. A message “Procedure Complete: Instrument operation has returned to normal.
19. Click “OK” button.
Temperature Probe Calibration:
Note: Before removing temp probe from the pipeline, read below:
1. Using HDR Host, go to the “Calibrate” column/ select “Calibration Wizard”.
2. The HDR will lock in the last read Temperature until the calibration is complete.
3. Remove the temp probe from the pipeline & place in insulated container of ice water (32DegF).
4. Select “Two point Temperature Probe 1 Calibration”.
5. Click “Begin”.
6. Temp Probe already has 32degF applied to the temp probe- measure with a standard temperature gauge.
7. Click “Next”.
8. Wait 10 seconds to get a stable reading and click “Next”.
9. Enter Temperature reading indicated by standard gauge and click “Next”.
10. Apply 115-125deg F to the temp probe (place in hot liquid in a insulated container)- measured with a standard temperature
gauge.
11. Click “Next”.
12. Wait 10 seconds to get a stable reading and click “Next”.
13. Enter Temperature reading indicated by standard temperature gauge.
14. Click “Next”.
15. At the calibration comparison screen, click “Done”.
16.
Select “Save” button to save the calibration.
17. Then click the “Finished” button.
18. A message “Procedure Complete: Instrument operation has returned to normal.
19. Click “OK” button.

Main battery change procedure: Download all data & backup the instrument first. Make sure the lithium backup battery
voltage is 3.5-3.6v. If an alarm is active, the display will be blinking (once a second). If an alarm is active, press the scroll button to
display the alarm description. The lithium battery alarm display will read: [Al lith]. If no alarms are displayed, pull the main
battery connector off and remove the main battery. Connect the new main battery and route the battery wire away from the index.
Secure the battery with o-ring. Note: No data will be lost during this procedure.

Instrument Configuration Backup procedure: Using HDR Host, select the “Configure” column, select “Auto Configure”,
select “Backup Instrument”, select “Save”.

Instrument Configuration Restore procedure: Using HDR Host, select the “Configure” column, select “Auto Configure”,
select “Restore Instrument”, select “Restore”, select the file to restore, Select only the items to restore or choose “All the above”.
