Sample Loading and Unloading Determination
(Zero Range)
The “Zero Range” value is used in the following functions as a reference for judging whether the sample is
loaded: Auto Print (
10.3
), Auto Zero(
10.4
), Peak Hold(
11.3
), Add-on Mode(
11.5
), Animal Weighing
Mode(
11.6
), and Formulation Mode(
11.7
). Set the "zero range" to a value suited to your purposes when
using these functions.
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 UP2202X (minimum display 0.01g) and each
measurement result is automatically output with the Auto Print “on Ld” function (
10.3
).
Suppose Zero Range is set to 10. As 1 count for UP2202X 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
48
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. Refer to 4.4 for numerical value settings.
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 the minimum display is switched to 10d (refer to 6.2), the minimum
display after the switch will be counted as one count for loading and
unloading determination.
As such, for the optimal zero range set before the switch, the value used
for loading and unloading determination may be too big, which could
result in the function not operating correctly (data not being output even if
a sample is loaded, etc.). Reconfigure the zero range settings when
switching the minimum display.
