General Description
Power Requirements
The HygroPalm AW1 operates with a regular 9V alkaline battery or with a 9V rechargeable
battery.
Important: the HygroPalm AW1 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 AW1 is available with an optional docking station. The docking station accepts an
external AC adapter. When the HygroPalm AW1 is equipped with a rechargeable battery, the
docking station can be used to recharge the battery (after turning on the battery charge function –
see settings). The RS232 port of the docking station is not used with the HygroPalm AW1 (this
port is used with other models of HygroPalm).
HygroClip Digital Probes
The ROTRONIC HygroClip digital humidity temperature probes permit to take full advantage of all
the features and functions of the HygroPalm AW1. These probes are highly accurate and are
calibrated entirely by means of software (no adjustment potentiometers). Because calibration and
other data are stored in the probe non-volatile memory, the probes are fully interchangeable.
When a probe requires calibration or has to be repaired, it can be replaced with another probe in
a few seconds.
The ROTRONIC HygroClip digital probes are available in different configurations so as to permit
different types of water activity measurement:
Power supply, 3.5mm Jack female
AC adapter 12 to 15 VDC, 100 mA
