8.9 LCD Backlight Brightness
The LCD backlight brightness may need to be adjusted. This is of
particular interest if multiple instruments are located in the same area
and it is desired for the entire group to have the same appearance. Ten
levels are available. The factory setting brightness is 8.
Change the brightness by pressing the
or
button. When the
desired brightness has been selected, press the
button.
8.10 RS-485 Parameters
These menus will only appear if the RS-485 is enabled (see 8.3). The
factory setting is 8 Bit, no (nOnE) Parity, 1 Stop Bit.
Make selections using the
and
buttons then press the
button
to move to the next menu.
8.11 Cycle Time
The cycle time can be changed using this menu.
Please note that
changing this menu will directly affect the volume of reagent
that will be consumed.
Make selections using the
and
buttons then press the
button.
Allowable setting is from 60 to 600 seconds (10 minutes).
NOTICE
The indicator reagent has a defined life after being mixed regardless
of the cycle time setting. If the reagent is kept in the powered cooling
chamber the life is 90 days.
8.12 Water Conservation
To conserve water, the flush time can be adjusted use as little water
as possible.
NOTICE
This feature is generally not used in ballast water applications and
should be set to OFF.
The instrument requires 110 seconds to complete its normal
operations, when the
WCON
is turned
On
, at the factory cycle time the
instrument sits idle for about 40 seconds. This results in about a 25%
water savings. The actual amount of water conservation is dependent
on the incoming water pressure and the cycle time setting.
The use of this option may result in some slight loss of accuracy. The
factory setting for this option is
OFF
.
Make selections using the
and
buttons then press the
button
to exit to
AUTO
mode and save all configuration settings. If the 4-20
mA in section 7.1 is turned ON, there are two additional menus that will
appear before returning to
AUTO
mode.
In addition to averaging, the CLX-Ex2 has a software filter that limits
the change between consecutive readings to 20%. For example,
the reading following a reading of 1.00 ppm could not be displayed
as higher than 1.20 ppm or lower than 0.80 ppm. This filter also
helps smooth out large changes and eliminate reading spikes. After
3 consecutive readings, it is assumed that the large change in the
readings is “real”, and the filter will be disabled. For example, the
change between reading 1 and 2, and readings 2 and 3 will be limited
to 20%, but the change between readings 3 and 4 will not be limited.
Note: This software filter is completely disabled when the averaging
(AVG) is set to 1.
