Since this pot is designed to use with its output is
connected directly to A /D port. lmpedance is considered
to be mega ohm level. Then contact resistance in the pot
is higher. Please refer to Flg-1. So when you use it in the
circuit like Flg-2.Please make sure that impedance should be
over than 1M-ohm.

〔Dew Condensation〕
Avoid using the product when condensation or drops of water might occur
inside the product. Otherwise, insulation deterioration or shorting may occur.
〔Soldering〕
Solder
PC board
Do not employ wiring designs and soldering methods as illustrated in the schematic drawing. Molten
solder flowing over the upper surface of PC board can cause imperfect contacts. Solder all metal
inserted fixing including terminals & metal lugs into a substrate.
〔Stress Being Applied to the Terminals〕
Always be careful not to apply excessive stress on the terminals. Design appropriate soldering conditions.
〔Handling of Variable Resistors Equipped with Switches〕
Exercise care when packing or storing. Packaging or storing while load is applied to the shaft may
cause a malfunction in performance.
〔Storage〕
① Store the products as delivered, at a normal temperature and humidity, without direct sunshine and
corrosive gas ambient. Use them at an earliest possible timing, not later than six months upon receipt.
② After breaking the seal, keep the products in a plastic bag to shut out ambient air, store them in the same
environment as above, and use them up as soon as possible.
③ Do not stack too many switches.
The above operation notes are quoted from the
“Precaution and Guideline of Potentiometer for Electrical Devices”, a technical report issued by the Japan
Electronics and Information Technology Industries Association EIAJ RCR-2191A
（in March 2002）
