3.1. Installation and Precautions
The AD-4406 weighing indicator is a precision electronic instrument. Handle the
indicator carefully.
The operating temperature is -10 to +40 (14 to 104 ).
Do not install the indicator in direct sunlight.
A malfunction or other problems may be caused by an unstable power source including
momentary power failure or instantaneous noise. Use a stable power source.
When an AC Adapter is used, please confirm that the local voltage and receptacle type
are correct for your indicator.
Use shielded cables for all connections. Connect the cable shields to the shield
terminal or case as an earth terminal.
Earth ground the indicator. Do not join the earth ground line with other electrical
power equipment.
Do not install the indicator in a place where it is apt to be charged with static
electricity, or where the relative humidity is lower than 45%RH. Plastic and isolators
are apt to be charged with static electricity.
3.2. Power Supply
When an AC adapter is used
A stable power source must be used; an unstable power source which includes an
instantaneous noise component may result in a malfunction.
When dry batteries are used
Use fresh batteries, preferably alkaline type. Insert batteries into the battery box (use
caution in inserting to match the polarity of the batteries), and insert the battery box
with the contacts to the inside of the indicator. Push it in and towards the bottom.
The battery box will hook onto the edge of the case. Install the cover over the battery
box so that it will not fall out.
To remove the battery box, press in and up on the end of the battery box. Slowly
release pressure on the battery box while holding it against the top of the battery
compartment and the battery box will slide out.
The AD-1681 rechargeable battery pack can be used in place of the standard battery
box.
