PARAMETER DESCRIPTION
With this menu it is possible to measure the temperature of the supply water, by means of an
OPTIONAL thermocouple K-type contact probe to be connected to the input T1.
Also, it is also possible to measure the temperature of the return water, by connecting an
OPTIONAL thermocouple K-type contact probe to be connected to the input T1.
With the function ∆T it is possible to obtain the relative temperature difference.
SEE SECTION 12.5.
It is possible, through the use of the external flexible pipe made in RAUCLAIR (supplied), to
measure a pressure value within the range stated in the technical features (connect the pipe to
P+ input). During the pressure measurement the 'HOLD' function is made available, which
allows to 'freeze' the value shown on the display, by pressing 'HOLD' key.
SEE SECTION 12.6.
The E4500 can perform the tightness test on heating plants which use combustible gases
according to the standards UNI 7129 and UNI 11137: 2012, respectively applicable to new or
renewed pipings and to existing pipings. The result of this tightness test, whose steps are
described in the following, can be printed, once acquired, by starting the ' print menu ' in any of
the screens of the ' Tightness Test ' menu.
SEE SECTION 12.7.
E’ possibile effettuare la misura della corrente di ionizzazione di una caldaia e la verifica del suo
valore in funzione delle caratteristiche tecniche della caldaia collegando la sonda di ionizzazione
(opzionale) alla porta seriale (Vedere paragrafo 4.3 e/o 7.4).
