TVA1000B Quick Start and Calibration Guide
1. Install filled hydrogen tank, attach probe/readout assembly, turn on analyzer andhydrogen supply valve.
2. Wait 4-5 minutes for proper hydrogen flow, then press 1 = Run. The unit will ignite
and display readings. If flame out message appears, clear the message (press Exit),
wait another minute and repeat step 2. If the unit has not been properly calibrated, a
bad calibration parameter error appears – go to step 3 below.
3. Press Exit until the Main Menu appears. Calibration can now be performed. For
best results, allow unit to warm up for 20 minutes, then press 2 = Setup.
4. Press 1 = Calib.
5. Press 2 = SpanConc.
6. Select the detector that the span concentration is for, then press the ↑ or ↓ arrow to
select the correct unit of measure for the span gas. Enter the span calibration value,
and press the Enter key. Repeat steps 5 & 6 for the second detector. Typically, the
calibration gases are methane (FID) and isobutylene (PID).
7. Next zero the instrument. Press 3 = Zero to start this process.
8. Press 1 = Both for dual detector units, or Enter for single detector units.
9. Introduce zero gas (< 1 ppm total hydrocarbon) into the analyzer through the probe.
10. Press Enter to start (this assumes manual mode, the factory default).
11. Wait for minimal change in values (about 15 seconds). Typically, the sample is
stable when the first 2 digits of the reading do not change for 4-5 seconds.
12. Press Enter to accept, then press 1 to save.
13. Next calibrate with the span gas. Press 4 = Span.
14. Select the detector to be calibrated, and press Enter to start. Follow the screen
prompts. Wait for the readings to stabilize (typically 10-15 seconds). Enter 1 to
save and repeat steps 13 & 14 for the second detector.
15. Press 5 = RF to verify proper response factor.
16. Confirm that response factor says “RF0: DEFAULT”. If not, set to this value.
17. Press Exit twice to return to MAIN MENU.
18. Press 1 = Run.
This completes the primary calibration, and the instrument is in the survey mode.
