Pressure Check - Ecom DP3 Operating Instructions Manual

6.4. Pressure check

The pressure check (long term measurement up to
1500 hPa or 20 bar with external pressure sensor) is
registered as a control pragram in the ecom-DP3.
Proceed as follows:
1. Scroll with the cursor keys <up/down> in the
menu "More measurements" to the menu point
„Pressure check". 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>). If the measurement time is set to
0, thecontrol program runs until it is interrupted.
3. Lock the gas pipe with a suitable adapter (test
stopple, high pressure stopple or one-pipe counter
cap) or connect the external pressure sensor.
4. Connect the components as described in
chapter 3.
5. Start the control program with <Enter> and built
up the adjusted pressure.
6. If the internal sensor (up to 1500 hPa) is used, the
needed pressure can be built up with the internal
pump (switch on and off with <F3>).
7. Wait for stabilisation time. If necessary the stabili-
sation time can be terminated with <F1>.
8. Once the measurement time is over (or with <En-
ter> if measurement time = 0), the result is displayed
and can be printed with <Print>.
9. If the menu „Pressure check" is selected again, so the result can be called
up with <F4> (as long as the ecom-DP3 is on) or a new measurement can be
started with <F1>.
