A voltage below 3.6 Volt switches of the electronics
completely. When connected to a charger, electronics will
switch back on.

7.2.8 Menu Item “Set Filter“
The filter can be averaged using a mathematical moving
average. The settings between brackets are the number of
mathematical points. Seven settings options are possible:
No [0]
Weak [36]
Very low [72]
Standard [144]
Medium [108]
Plus [180]
Strong [216]
Max [255]
This value influences the time response. For a fast time
response a filter can be best set to “Weak”.
A reading of [0] will be very nervous.
For a more stable reading a filter can be best set to
“standard [144]”
7.2.9 Menu Item “Baud Rate”

10.4 Battery
Charging the battery takes approximately two hrs.
On a full charge the thermometer is capable to work sixteen
hrs.* continuously.
The thermometer can be connected permanently to the
wall socket. However repeatedly cutting power will
initiated forced charging and this may shorten the
battery’s lifetime. The red LED lights when a charging
cycle starts.
When the battery runs empty, a battery sign is displayed. If
this sign is displayed, connect the battery charger.
When the battery is being charged, the red LED on the front
will light.
The LED is switched off when the battery is full.
If the battery is charged before the battery sign is displayed,
less time is needed to charge the battery.
Do not use a charger other than supplied. Following
harms the battery’s capacity and it’s lifetime.
Higher voltage than 9V
Lower voltage than 8V
Current supply <500mA
The charger has following characteristics:
- 9V
- 600mA
- input voltage 100-240~50/60Hz
- Plug 2.0 .. 2.1 x 5mm
