2. Basic Operations

CAUTION
●
Operate away from direct sunlight at a stable temperature with as little
fluctuation as possible.
●
Acclimate both the instrument and sample solution to room temperature to
ensure accurate results. Measurements may fluctuate with hot or cold samples.
Wait to press
F
after placing the sample on the prism. Alternatively, press
F
multiple times
.
●
Operate on a flat work surface.
●
The displayed temperature is that of the prism and may not necessarily match
the temperature of the sample.
1. Zero-setting
This is the operation to set the calibration point (zero) for optical rotation and Brix
.
m
Zero-set the instrument at the beginning of each day before use.
m
Regular zero-setting throughout the day is recommended to ensure accurate results.
①
Press
I
to turn it on.
m
Optical rotations and Brix can be
zero-set in any scale, however, when
the optical rotation scale is selected,
even when Brix zero-set is an error, no
error message will display.
②
Wipe the sample stage clean.
③
Fill the sample stage with tap water up
to the fill line.
N
Use room temperature tap water. The
instrument should also be acclimated
to room temperature prior to
operations.
④
Press
G .
000
flashes and stops.
N
To perform zero-setting on the optical
rotation scale and check whether Brix
zero-setting was done correctly, press
K
and check that 000 is displayed.
