5.3.3. Pressure test 0 – 40 bar
The pressure test 0 - 40 bar at liquid gas pipes is
registered as a control pragram in the
ecom-DP3
.
Proceed as follows:
1. Scroll with the cursor keys
<up/down>
in the
menu
"Liquid gas"
to the menu point
„Pressure
test 0 – 40 bar“
. Activate the menu point with
<En-
ter>
.
2. Check if necessary the values of stabilisation time,
measurement time and test pressure with
<F1>
(back with
<ESC>
).
3. Connect the external pressure sensor to the liquid
gas pipe.
4. Connect the external pressure sensor as de-
scribed in chapter 3.
5. Start the control program with
<Enter>
(the pump
of the instrument is building up the adjusted pres-
sure).
6. Wait for stabilisation time (if the pressure remains
in the range „test pressure - 10%" during stabilisation
time, so the measurement time will start). If neces-
sary the stabilisation time can be terminated with
<F1>
.
7. Once the measurement time is over, the result is
displayed and can be printed with
<Print>
.
8. If the menu
„Pressure test 0 – 40 bar“
is select-
ed again, so the result can be called up with
<F4>
(as long as the
ecom-DP3
is on) or a new meas-
urement can be started with
<F1>
.
