13.5 Zero Range
The “Zero Range” value is used in the following functions as a reference for judging whether the sam-
ple is loaded: Auto Print (
13.3 ), Auto Zero( 13.4 ), Peak Hold( 14.3 ), Add-on Mode( 14.5 ), Animal Weigh-
ing Mode( 14.6 ), and Formulation Mode( 14.7 ).
If the display is within the Zero Range, the balance determines that the balance is not loaded. If the
display reaches five times the Zero Range or more, it determines that a sample is loaded. Functions
which involves judgment of whether a sample is loaded or not work in accordance with the Zero Range
setting.
Example : Samples are weighed one after another with UX2200H (minimum display 0.01g) and each
measurement result is automatically output with the Auto Print “on Ld” function (
13.3 ).
Suppose Zero Range is set to 10. As 1 count for UX2200H is 0.01g, Zero Range is 0.10g in
this case. When a sample of 0.50g or more is placed, it is judged to be loaded and the data
will be output. When this sample is removed and the display returns below 0.10g, it is
judged that the balance is unloaded, then it is ready for the next sample. If it does not return
below 0.10g, the previous sample is not judged to be unloaded. Therefore, even when the
displayed value reaches 0.50g again by next loading, the data will not be automatically output.
Select Zero Range value according to the influences of environment (causing difficulty in
zero-return), the weight of the samples, etc. so that Auto Print functions properly.
Set the “Zero Range” value with menu item using the number of counts displayed in gram-display.
The setting range is 01 to 99 with 10 being the default value. Even when weighing will be done in
another unit, Zero Range setting is made by only gram value.
Notes
• Zero Range value is a common setting for all the Zero Range-linked
functions.
• The application of Zero Range value is different depending on each
function. Refer to the section of each function using Zero Range.
• When a Pretare value is set, the thresholds to determine that there is
“no load” becomes “
−
Pretare
±
Zero Range”.
• When minimum display is changed to 10d (See 9.2 ), number of counts
used for load/unload judgment is counted based on the 10d minimum
display. Therefore, the Zero Range value optimized for 1d display can
be too large for 10d display. This may cause failure of linked operation,
e.g. automatic output upon loading. Optimize Zero Range value again
when switching minimum display 1d/10d.
