3.4 AC Power Adapter
The Pur•Chek™ Pro is powered via a 110/220 VAC, 50/60 Hz power transformer. This transformer is included
with each unit and converts a standard 110/220 VAC, 50/60 Hz wall outlet to 12VDC to power the device. An
optional internal and rechargeable battery kit is available separately. Note: Use of any other power source may
cause damage to the unit and void the warranty.
3.5 Control Panel
The Control Panel serves as the main user interface. The Control Panel features three soft key buttons that
change their function as the instrument changes modes. The current function for each button is displayed by
the soft key label at the bottom of the graphic display. Red and Green LED’s at the top of the Control Panel are
used for visual status indications.
