How the instrument functions in the RUN mode is governed by the selection made in the
SETUP/LOG menu. The LOG menu selects how data is stored in the instrument memory.
There are four possible choices in the LOG mode as defined in “Log Methods” on page 38.
The TVA-1000B performs accurately only after it has been properly set up (configured).
The three RUN mode displays (as governed by the LOG Selection) are:
NONE
AUTO, VOC, or F.E.
PID: 80.00 ppm
FID: 80.00 ppm
Exit=Stop
PID: 80.00 ppm
FID: 80.00 ppm
Sampling: 10 sec
Exit=Cancel
If your instrument is equipped with an FID, you should turn the red hydrogen supply valve to
ON and wait 2-3 minutes before entering the RUN mode. Upon entering the RUN mode,
the pump will automatically turn ON and the FID will ignite.
NOTE: For best performance, prior to entering the RUN mode, the instrument must
be ON, warmed up for approximately 15 minutes, and display the main menu. The
pump must also be ON throughout the warmup period. If the instrument is FID
equipped, and the FID is to be used, the flame must be ignited throughout the
warmup period. If the instrument is PID equipped and the PID is to be used, the
lamp must be ON throughout the warmup period.
