START-UP
INSTRUMENT POWER ON
When the POWER switch is turned on or RESET is pressed,
the moving words “Hanna PCA300” will appear. This dis-
play will continue for 20 seconds.
Then the concentration is set to
0.00 mg/L.
An indication appropriate to
the key pressed or, after 5
minutes, the first mg/L read-
ing will appear on the display.
Note The SYS.ERROR LED and relay will not activate before the
first reading.
Be sure the sample stream is open and flowing through the
system. Wait long enough for the tubing and colorimeter to
be flushed and filled completely and for the reading on the
digital display to become stable.
If no priming action is taken, one or two hours may be re-
quired to initialize the instrument. Faster stabilization can be
obtained by priming the reagent pump and tubing using the
provided operational code.
DISPLAY BRIGHTNESS
The display brightness is set at the highest level. The analyzer
offers the option to change it at two lower levels.
• Press DIAG. The display will show the last diagnostic mode
and the right-most numerical digit will blink.
Note If the analyzer has been reset or turned on, “d000” will ap-
pear when pressing DIAG.
