Solid Standard
The Solid Standard is designed to verify the stability of the instrument by checking drift of the calibration.
It will also verify if any instrument settings have been changed.
1. After calibration, insert the Solid Standard into the sample compartment of the TBS-380 Mini-
Fluorometer. (
NOTE
: always insert it with the tab away from you)
2. Press the
READ
button.
3. Confirm that the current measured value does not deviate from previously recorded value by 5% or
more. If the value of the Solid Standard deviates by more than 5%, it is time to recalibrate the
instrument (see 3.5).
4. Record the reading.
5. Check the calibration and/or the stability of the instrument by periodically reading the Solid Standard.
