*The characteristics of sample reagent has errors due to
sample tests such as uneven density (%TS, consistency)
distribution.
*Full scale is the maximum value in the measurement range,
which is the upper limit setting range.

Less than full-scale 2%TS
Note: The values are taken at measuring points above 5% of
full-scale using simulated reagent.

determination repeatability
* The density (%TS, consistency) determination resolution
stated above is defined due to manufacturing limitation to
make reagents with stable distribution and a minimum
difference of fluid density (consistency).
<Notice>
1. Install a sample tap near the LQ500 as close as
possible to get an accurate density (%TS,
consistency) measurement using the LQ500.
2. Take several samples in rapid sequence for
more accurate density (%TS, consistency)
measurement with less human error factors.
