GENERAL OPERATING PROCEDURES
METER
When a fi lled disk is placed in the chamber and the lid is closed, the meter spins at high
speed to distribute the sample to the test wells. Next the meter slows to maximize the
pumping action of the stainless steel mixing beads as the reagents mix with the sample
water. Each reaction is then read at the proper time and wavelength for that reagent
system.
The button located in the lower center of the top of the meter turns the
instrument on and off .
The Blue indicator light of the on/off button indicates the status of the instrument.
Steady blue light
– the blue LED will remain steady to indicate that the meter is on and
ready to run a test.
Blinking blue light
(three blinks/second) – a test is in progress and the disk is spinning. Do
not open the lid when the disk is spinning.
Care should be taken when closing the lid. Do not slam the lid. Wiring between the lid and
the body of the photometer passes through the hinge. The meter will not run with the lid
open.
TOUCHSCREEN DISPLAY
When the button is pressed to turn the meter on, the Test Screen will be displayed.
