3.2 LOCATING
 The scales should not be placed in a location that will reduce
the accuracy.
 Avoid extremes of temperature. Do not place the scale in direct
sunlight or near air conditioning vents.
 Avoid unsuitable surfaces. The table or floor should be rigid
and free from vibration.
 Avoid unstable power sources. Do not use the scale near
large users of electricity such as welding equipment or large
motors.
 Do not place the scale near vibrating machinery.
 Avoid high humidity that might cause condensation. Avoid
direct contact with water. Do not spray or immerse the scales
in water.
 Avoid air movement such as from fans or opening doors. Do
not place the scale near open windows or air-conditioning
vents.
 Keep the scales clean. Do not stack material on the scales
when they are not in use.

 To return to normal weighing, turn the scale off and back to on
again or press the key.
13.2.1 FILTER
This parameter is for setting the speed of the display filter. For
poor environments the filter should be set at its slowest to minimise
external influences on the scale. For weighing small samples
or gradual filling, the filter should be set at a faster setting.
Press to scroll through the options. The display will show
“FiL 1” to “FiL 3”. If it is set to “FiL 1” then the display is at its
slowest setting and at “FiL 3” the display is in its fastest setting.
13.2.2 ZERO TRACKING
This parameter is for setting the range of the zero tracking. Zero
tracking will aid the scale to hold or return to zero and should be
increased if large weights are left on the scale or temperature is
not consistent.
Press to scroll through the settings. The display will show
“ZEo 1” to “ZEo 8”. If it is set to “ZEo 1” the zero tracking is at its
smallest range and “ZEo 8” the highest.
13.2.3 STABILIZATION RANGE
This parameter is for setting the range of the stability indicator. This
is used to determine when the scale will print automatically
as well as indicate that the weight is stable.
Press to scroll through the settings. The display will show
“StA 1” to “StA 8”. If it is set to “StA 8” then the stability is at its fastest
and “StA 1” the slowest.
