About Your eXact
®
Eco-Check Instrument
In order to save power, the meter is designed to turn off after 3 minutes (timed
from the last button pressed).
Should the meter turn off in the middle of a test, the last stored zero in the meter
will remain valid when the meter is turned on again. Also, the test result is stored
in memory for easy retrieval.
The eXact
®
Eco-Check meter is controlled by three buttons:
1.
ZERO/ON

meter is on and this button is pressed, it zeroes the sample in the cell. Once the
meter is zeroed, this zero value applies to all parameters and is stored and
retained even when meter turns off. However, it is recommended that each new
water sample analyzed is zeroed before testing, to maximize sensitivity and
accuracy.
2.
MENU
: With each press, the MENU button advances through the tests in the
following sequence: AL1, NO2, NO3, NH4, TH5, CL6, bt7, PO8, CU9, CH0, P11.
Each test menu can store up to 20 results. To
retrieve the stored results
, go to
the desired test using the MENU key. When the desired test is displayed,
press
and hold down the MENU key
. Continue holding down the MENU key to scroll
the stored results for that test, starting with the most recent result. The meter will
display, from memory, the last 20 readings in sequence beginning with -20, which
is the latest result, followed by -19, which is the 2

-01, which is the oldest result retained. Only the last 20 readings are stored in
each menu. This meter is able to store 220 results in memory (20 in each menu).
3.
READ
: When pressed once, this button starts the timer for the parameter
being tested and proceeds for each test procedure. When pressed a second time
the meter exits the timer and immediately prepares to colorimetrically measure the
sample (not accurate, for accurate results you need to wait the entire reaction
time) and simultaneously stores the measurement in memory.
If the parameter being measured is below or above the detection range, the display
will show “
LO
” (Under Range) or “
HI
” (Over Range), respectively. This feature is
