General Description
Power Requirements
The HygroPalm operates with a regular 9V alkaline battery or with a 9V rechargeable battery.
Important
: the HygroPalm is shipped with a regular 9V battery and is factory preset with the battery
charge function turned off. If you plan on using a rechargeable battery (requires docking station), you
should turn on the battery charge function (see Function Menu – Settings). Before using a regular battery
again, be sure to turn off the battery charge function. Trying to charge a regular battery may cause the
battery to burst and may damage the instrument.
Optional Docking Station (PalmDock)
The HygroPalm is available with an optional docking station. The docking station accepts an external AC
adapter for recharging the battery. Models with an RS232 port can be connected to the COM port of a PC
via the docking station.
