4. Initialisation

4.1. Power supply

The ecom-DP is powered by 3 batteries. The following
types can be used to operate the instrument:
- Battery 1,5 V AA (Mignon)
- Battery 1,2 V AA NiCd (nickel cadmium)
- Battery 1,2 V AA NiMh (metal hydride)
If you are using a battery 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 automat-
ically switch off.

4.2. Battery charging

The battery charging procedure is monitored by the
ecom-DP. Once connected to AC power, the instrument
switches on. During the charging procedure, a BATTERY
indicator will be shown on the LCD display. Once the bat-
tery is fully charged, the BATTERY indicator on the dis-
play 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 using
the ecom-DP for the first time, adjust the internal clock
and delete the internal RAM memory.
