4. Initialisation
4.1. Power supply
The ecom-DP is powered by 3 batteries or 3 accumula-
tors. The following types can be used to operate the
instrument:
- Battery 1,5 V AA (Mignon)
- Accu 1,2 V AA NiCd (nickel cadmium)
- Accu 1,2 V AA NiMh (metal hydride)
If you are using a accu charger, please adjust the func-
tion „Bat. Loading“ (see chapter 8.4.)
Open the battery compartment and insert the batteries.
Be careful to ensure proper polarity. If using the re-
chargeable battery type, it will be necessary to fully
charge the batteries prior to initial use (approx. 4 hours).
The voltage of the batteries is monitored by the DP and
will indicate a low battery condition by approx. 3.3 V by
beeping and flashing a signal on the LCD display. If the
voltage sinks (approx. 3 V) so the ecom-DP will auto-
matically switch off.
4.2. Accu charging
The accu charging procedure is monitored by the ecom-
DP. Once connected to AC power, the instrument
switches on. During the charging procedure, a BAT-
TERY indicator will be shown on the LCD display. Once
the battery is fully charged, the BATTERY indicator on
the display will blink. It is possible to operate the ecom-
DP on AC power during the charging procedure by
pressing the <ON> button.
4.3. Setting clock
The internal clock and the internal RAM memory of the
ecom-DP are buffered via a capacitor. If the instrument
is without current supply during more than approx. 10
minutes, the recorded information gets lost. Before us-
ing the ecom-DP for the first time, adjust the internal
clock and delete the internal RAM memory.

sor will be displayed: denomination, measurement
range and connection seizure (+/-). Press <OK> to
access to the measurement value menu.
5.1. Zeroing the internal pressure sensor
Please remember not to flow the pressure sensors
with pressure during the zeroing procedure.
As the difference pressure sensor can drift because of
its sensitivity in the zero point, it is possible to reset the
zero point.
- Press <F4> (P1) to zero the value of the pressure
sensor.
Different functions can be called up with the function
key <F1>. The current seizure of the other function keys
(<F2> - <F4>) is shown on the display. Press one time
<F1> to display the functions „Hold“, „Min/Max“ and
„Print“.
5.2. Freezing of measurement value
- Press <F2> (Hold) to „freeze“ that measurement value
displayed at the time the key is pressed (active function
Hold indication blinks).
- Press again <F2> (Hold) to quit the „freezing“ and the
current value will be displayed.
1. Before making measurements, the instrument must have
adapted the ambient temperature!
2. Make sure, that the ambient temperature remains constant
during measurement!
If „Pressure Auto -> O by start“ is set on
„YES“ (Chapter 8.2), so the internal pres-
sure sensor should be flown with pres-
sure first after the switch-on of the in-
strument, as they are zeroed during
said switch-on procedure.

determined values (Min/Max blinks).
- Press <F2> (CLR) to delete the minimal values (new
scanning begins).
- Press again <F3> (Min) to view the highest values
(Min/Max blinks).
- Press <F2> (CLR) to delete the highest values (new
scanning begins).
- Press one more time <F3> (Max) to quit the menu.
5.4. Printout measurement values
Press <F4> (Print) to transmit the current measurement
values via the infrared interface to the IR printer (op-
tion).
Condition hereto is a trouble free connection (direct
sight) between the sending diode at the front of the in-
strument and the receiving diode of the printer. The
distance between both instruments should not exceed
40 cm (1.3 foot), otherwise a trouble free transmission is
not warranted at any time.
The printout can be made with the infrared printers
ecom-P and HP 82240B. Please choose the used print-
er, as shown under capter 8.3.
5.5. Contrast adjustment and lighting
Basing on the previous function seizure, the functions
„LUMI“ and „Light“ are displayed after pressing <F1>.

11. Data logger program „ecom-DP Logger“
The measured value process of the ecom-DP can be logged with the help of the
data logger program „ecom-DP Logger “. The program can be loaded free of
charge from the download area of the ecom homepage www.ecom.de. To trans-
fer the data a USB cable (kind becomes. - No.: 55818) and a driver (free down-
load from www.ecom.de) is needed. The measured value rows can be stored in
the xls format (Excel).
The USB cable can be used as the power supply for
the ecom DP. Therefore the function „Battery loading“
must be adjusted on „no“ when using
1,5 V AA (Mignon) batteries (see 8.4.)!
