Functional description:
Light High:
There is too much light to perform a
measurement. Please check the preparation of the
zero cuvet.
Light Low:
There is not enough light to perform a
measurement. Please check the preparation of the
zero cuvet.
No Light:
The instrument cannot adjust the light
level. Please check that the samples does not contain
any debris.
Inverted cuvets:
The sample and the zero cuvet
are inverted.
Zero:
A zero reading was not taken. Follow the
instructions of the measurement procedure for zero-
ing the meter.
Under range:
A blinking
“0”
indicates that the
silica content in the sample is less than 0 mg/L.
Over Range:
A flashing value of the maximum
concentration indicates an over range condition. The
concentration of the sample is beyond the
programmed range: dilute the sample and re-run
the test.
Standard Low:
The standard reading is out of
range.
Standard High:
The standard reading is out of
range.
Errors and warnings:
Measurement procedure:
1•
Turn the meter on by pressing
ON/OFF
.
2•
When the beeper sounds and the LCD
displays dashes, the meter is ready.
The blinking
“ZERO”
indicates that
the instrument needs to be zeroed first.
3•
Fill the cuvet with 10 mL of unreacted
sample, up to the mark, and replace the
cap.
4•
Place the cuvet into the cuvet holder
and ensure that the notch on the cap
is positioned securely into the groove.
5•
Press
ZERO/CFM
and the instrument
status indicator will appear on the
display, depending on the measurement
phase.
6•
After a few seconds the display will
show
“-0.0-”
. The meter is now
zeroed and ready for measurement.
7•
Remove the cuvet.
8•
Add the content of one packet of
HI 96770A-0 Silica HR reagent A
and shake until complete dissolution.
9•
