When the pressure in the
furnace exceeds 3 kPa, it is
recommended that you
compensate the pressure.
When the pressure in the
furnace exceeds 5 kPa, you
must perform pressure
compensation. For 0.15m
probe, 0.5 to 5 kPa. No
pressure fluctuation in the
furnace should be allowed.
(Note 2)
Downward oriented mounting
