device for a whole range of measure-
ment and control applications in the
laboratory and in industry.
A micro-processor controls the electro-
nics, guaranteeing maximum measu-
rement precision and linearity over the
entire measurement range.
You may attach a range of ebro sensors
to the thermometer TFX 410-1 and TFX
430, selecting the one most suitable for
your technical measurement application.
With the TFX 410 the probe is rmly
attached.

Position the measuring sensor.
Use the measuring sensor only as
intended so as to eliminate erroneous
measurements.
Wait until the measured value has
stabilised. The trend display shows
a downward pointing triangle for
decreasing (4) temperatures and an
upward-pointing triangle for increasing
(3) temperatures.
The trend display disappears once the
measurement value becomes stable.
Switch the device o with »ON/OFF«
when measurements are complete.
If special adjustment is activated „SCAL“
will be shown in display for a short
while.

5 Changing sensor
The thermometer has been calibrated
at the factory. Measurement precision
may be impaired erent measu-
rement probe is attached
1. Grab the probe cap (with TFX430, go
to point 2 directly) at the recessed
grip planned for it and turn this 60°
anticlockwise. At the beginning of
the turn a noticeable resistance is
to be overcome. Pull the probe cap
downwards.
Do not pull the at the probe pipe!
2. The probe plug-in connector is
visib le now. Pull out the
sensor downwards by pulling at the
plug-in connector.
Do not turn!
3. Plug in a new probe or extension
cable where required. Ensure
the connection is secure.
The connector must be engaged!
4. Slide the protective cover over the
plug-in connector and turn 60°
clockwise to lock again (not with
TFX430).
