H Notes:
If the calibration process has been interrupted during
the procedure the system will time out (indicated by
fi ve short beeps) after approximately 6 seconds and
return to the measurement mode with the setting fac-
tors unaltered.

QUENCE WILL RESTART the procedure will then
restart at step 1 as in the table above. This setting
procedure can be aborted at any time by pressing the
MENU button.
Because the air temperature can be different from the
STD sample temperature, it is recommended that the
probe is placed on the STD, for approximately 10 sec-
onds prior to the set procedure and held on each block
for 5 seconds before
SET is pressed (steps 3 and 4
above). By allowing the probe temperature to settle to
that of the STD blocks optimum setting is ensured.
