3INSTALLATION
3.1 Unpacking
Unpack and verify that the following components have been
included:
a) NANO Precision Scale
b) Instruction Manual
c) AC Adapter
d) Draft Shield with cover - mounted on NANO scale
e) SS Pan on top.
Save the packaging material. This packaging ensures the best
possible protection for the storage or transport of the product.
3.2 Placing your scale
Before you install the scale, identify the best location for the
equipment. The proper environment enhances its operation and
longevity. Keep in mind the following factors, which might have
a negative influence on the scale's operation:
a) Vibration: Vibration diminishes the scale’s ability to measure
accurately. Electrical machinery such as conveyors and drill
presses can cause inaccurate and non-repeatable readings.
The scale may also read inaccurately if it is not leveled
properly. The scale incorporates a SMART weighing mode

NANO Series Precision Balance
5
where the scale can reject readings with vibration up to
some extent.
b) Drafts / Air currents: Moving air can cause the scale to read
wind movement as an additional force and cause
inconsistency in the weighing results.
c) External Rubbing / Friction: A scale cannot measure
accurately if an object is rubbing or pressing against the
scale platform.
3.3 Leveling the scale
Level the scale by turning the adjustable feet. It is leveled
correctly when the bubble indicator is in the center of the circle.
3.4 Power Source
The unit works on 220V AC Level the scale by turning the
adjustable feet. It is leveled correctly when the bubble indicator
is in the center of the circle.
The scale is fitted with a built in 6V 4Ah battery which provides
backup of more than 45 – 70 hours depending on glow setting
and sleep mode setting.
3.5 Calibration Check
Put a known weight on the machine and make sure that the scale
reads the correct weight on the display. In case of a variation in the
display reading, it is recommended to calibrate the scale again with
the procedure explained in section 7.1 later in the manual.
