3 Preparing the measuring probe

CAUTION!
Incorrect battery setting (default setting: lithium)
If the setting of the battery type does not correspond to the type of battery used, this leads to significant
loss of battery operating life or to malfunction of the low battery detection.
 Make sure the setting on the measuring probe or setup program is correct.
NOTE!
A mixed operation of alkaline and lithium batteries can also result in the abovementioned faults. Always
use batteries of the same type and charge.
CAUTION!
Possible data loss
If measuring and transmission intervals are selected that are quicker than the default settings (especially
in the case of 2 sensors), this will shorten the battery operating life, which leads to shorter alarm times
between battery low and battery empty (only hours in extreme cases). In the worst case, the alarm time
is approx. 2 % of the battery operating life calculated by the calculation program.
For the voltage supply of the measuring probe, 4 × FR6 or LR6 1.5V AA batteries are required. Lithium
batteries and alkaline batteries are admissible. The battery operating life depends on the sensors used
(type and number), the selected measuring and transmission intervals, the ambient temperature, and
the battery type. Recommended lithium battery: Energizer Ultimate Lithium AA-L91-FR6-1.5V (this type
of battery is part of the measuring probe equipment).
The measuring probe has been optimized for the recommended lithium battery. The recommended bat-
tery type achieves the best results, particularly when operating CO
2
sensors with high peak voltage
loads. On account of its high capacity, this lithium battery guarantees the maximum battery service life,
even at minus temperatures.
Recommended alkaline battery type: Duracell Ultra Power AA-MX1500-LR6-1.5 V (not available as an
accessory). If alkaline batteries are used, an adjustment of the measuring probe to this battery type is
recommended to optimize its lower capacity and to safeguard the battery low function. This type of bat-
tery is less suited to the operation of CO
2
sensors. The probe can be adjusted using the operating keys
or the setup program, see chapter 9.2.2 "General parameters", Page 48.
CAUTION!
Battery assortment
Due to the large assortment of batteries, it cannot be guaranteed that the measuring probe will work
fault-free with each type of battery commercially available.
 Use the recommended lithium or alkaline batteries.
