User adjustment
The adjustment should be made in new
and unused deep-frying oil and it must
be done at a temperature of 150 °C to
190 °C / 302 °F to 374 °F.
An adjustment is to be made to the
typical fresh oil values for the oil type
depending on the oil used.
Preparation: Before the adjustment the
FRPC-value (see quick oil settings)
should be that of fresh oil. A test mea -
surement should be performed with the
device before the first adjustment. The
sensor is warmed up by this means to
accelerate he adjustment procedure.
Execution
• Switch on FT 440 (push ON/OFF).
The device is ready for the measu -
rement to be made.
• Press and hold the DOWN button
for 5 seconds. “CAL” will then
appear in the display.
• The adjustment procedure begins
as soon as “CAL” appears in the
display; this is done by dipping
the FT 440 sensor into the frying
oil. (Observe the MIN and MAX
markings!)
• The adjustment procedure ends as
soon as there is a stable measured
result and “OK” is shown in the
display.
