How to replace exhausted alkaline batteries
Open the top cap/observation well cover.
Pull and hold the communication unit approximately 1 m out of the observation
well (a second person would be useful).
Remove the screw fitting from the communication unit.
Slide the cap and pipe casing of the communication unit approx. 50 cm
towards the pressure probe cable. (The rubber stop located on the pressure
probe cable (refer to Fig. 2) prevents the pipe casing from falling.
Do not move the rubber stop!)
Open the Velcro strip above the battery holder.
Remove the battery holder from the battery compartment.
Remove the cap of the battery holder by rotating it counter-clockwise.
Remove the exhausted alkaline batteries and make sure not to pull the lead!
Within 10 minutes, insert 2 alkaline batteries (LR14 · AM-2 · MN 1400 · C)
into the battery holder as shown in figure 4 (ensure that the polarity is correct)
an install the cap of the battery holder by rotating it clockwise.
Insert the battery holder into the battery compartment.
Firmly close the Velcro strip of the battery holder around the battery holder.
Slide the cap and the pipe casing of the communication unit back up to the
stop.
Please note:
Do not bend or pinch the battery holder lead.
Reinstall the screw fitting to the communication unit.
Slowly and carefully reinsert the communication unit into the observation well.
Close the top cap/observation well cover.
If you want to change from the currently used battery holder containing 2 alkaline
batteries (LR14 · AM-2 · MN 1400 · C) to lithium batteries prior to using the unit
follow the steps below:
Disconnect the battery holder cable from the socket of the electronic unit.
Carefully pull the plug straight upwards.
Open the Velcro strip above the battery holder.
Remove the battery holder from the battery compartment.
Insert the lithium battery as described in Chapter 5.1.
Notes
The OTT ecoLog 800 (3G) stores the measured values in a non-volatile memory.
There is no loss of data when changing batteries.
This also applies to storage without batteries for a long period.
If replacing the batteries takes longer than approx. 10 minutes the time (and
possibly the date) will have to be re-entered, refer to Chapter 15, "Setting date
and time". Furthermore, it takes – dependent on how much data is stored – up
to 7 minutes until the OTT ecoLog 800 (3G) starts measuring again (during this
time, the OTT ecoLog 800 (3G) re-initializes its database).
When replacing the batteries, we recommend changing the desiccant capsules
at the same time, refer to Chapter 18.2, "Replacing the desiccant capsules".
