Interferences Configuration (TC Sensor)
A number of different interfering gas options are
available (temperature, H
2
O, He, O
2
and H
2
),
depending on the instrument configuration and
the gas being measured.
• Temperature compensation: If there is a
significant fluctuation in the sample
temperature enable temperature
compensation to reduce the influence of
these temperature fluctuations.
• Interfering H2O: This only applies to
measurements taken in 100% humid
gases or in traces of dissolved gas in
water. It allows a correction to the slope
and temperature coefficients calculated
during calibration.
• Interfering gas: Enable this option to
allow the instrument to correct for the
presence of specific gases in the sample.
If the interfering gas is helium, you can
enter the concentration percentage if
known.
Measured Data Storage
There is one measurement file per channel which
contains the data generated by the measurement
cycle. The current measurement files are updated
in volatile memory, and are regularly copied in
non-volatile memory (file back-up). At start up, the
measurement files in volatile memory are updated
with the files from the non volatile memory.
Adjust the parameters for recording and storing
measured data. Two storage mode selections are
available depending on the measurement mode
selected:
Continuous measurement mode:
• No storage
• Store once: When volatile memory is full
(10,000 positions), measurement
recording stops
• Rolling buffer: When volatile memory is
full, the latest measurement set replaces
the oldest (first-in, first-out basis)
Sample measurement mode:
• Only final measurement: The
measurement when the stop criteria are
met is saved (one per sample)
• Only when sample mode started: The
measurements when the sample mode is
started are saved
• All measurements: All measurements
stored continuously
Additional parameters:
• RAM time (volatile memory): Delay in
seconds between two recordings of
measured data.
• FLASH time (non-volatile memory):
Delay in seconds between two data file
transfers from volatile memory into non-
volatile memory. Last data file erases
previous one.
Buttons:
• Purge data: Clear all data in the volatile
and non-volatile memories
• Start logging measurement: In store once
mode, starts and stops the measurement
recording session. Measurement
recording is stopped when buffer is full
• Open data 1,2, or 3 (and TPO or TPA
data if enabled): Opens the table
showing the measured value which are
stored in the volatile memory (RAM)
