Pressure Test - Ecom DP3 Operating Instructions Manual

5.4.1.2. Pressure test

The pressure test acc. to DIN EN 806-4 at drinking
water 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 "Drinking water / Drinking water plant wet"
to the menu point „Pressure test wet". Activate the
menu point with <Enter>.
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
drinking water pipe.
4. Connect the external pressure sensor as de-
scribed in chapter 3.
5. Start the control program with <Enter> and and
built up the adjusted pressure.
6. Wait for stabilisation time (if the pressure remains
in the range „test pressure +/- 10%" during stabilisa-
tion time, so the measurement time will start). If nec-
essary 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>.
