Pressure Test 0 - 40 Bar - Ecom DP3 Operating Instructions Manual

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>.
