Set Delay
The delay function sets the amount of damping on the instrument. This
function allows the user to apply a first order time delay function to the
ClO
2
measurements being made. Both the display and the output value
are affected by the degree of damping. Functions such as calibration are
not affected by this parameter. The calibration routines contain their own
filtering and stability monitoring functions to minimize the calibration
timing. Press ENTER to initiate user entry mode, and the value will
flash. Use the arrow keys to modify value; range is 0.1 to 9.9 minutes.
Press ENTER to store the new value.
Contrast
This function sets the contrast level for the display. The custom display
is designed with a wide temperature range, Super-Twist Nematic (STN)
fluid.
The STN display provides the highest possible contrast and widest
viewing angle under all conditions. Contrast control of this type of
display is generally not necessary, so contrast control is provided as a
means for possible adjustment due to aging at extreme ranges. In
addition, the display has an automatic temperature compensation
network. Press ENTER to initiate user entry mode, and the value will
flash. Use arrow keys to modify the value; range is 0 to 8 (0 being
lightest). Press ENTER to update and store the new value
.
Main Units
This function allows the user to select either PPM or mg/l for the ClO
2
measurement.
Zero Filter
This function forces the reading to zero when reading is below the
entered value. For example, If the entered value were 0.0020 the display
at 0.0019 would then indicate 0.0000. This feature is useful in blanking
out zero noise.
Main Display
This function allows the user to change the measurement in the primary
display area. The user may select between ClO
2
, sensor temperature, or
output current. Using this function, the user may choose to put
temperature in the main display area and ClO
2
on the secondary, lower
line of the display. Press ENTER to initiate user entry mode, and the
entire value will flash. Use the UP arrow key to modify the desired
display value. Press ENTER to store the new value.
Com Mode
Sets digital communication mode of analyzer. Optional digital
communication card must be plugged into the power supply slot for this
function to work. Press ENTER to initiate user entry mode, and the
entire value will flash. Use the UP arrow key to modify the desired value;
selections include 1-None, 2- P-DP for Profibus DP, 3
– Modbus, 4 –
Ethernet IP. Press ENTER to store the new value.
Com Address
Sets bus address for digital communication mode of analyzer. Optional
digital communication card must be plugged into the power supply slot
for this function to work.
Press ENTER to initiate user entry mode, and the entire value will flash.
Use the UP arrow key to modify the desired value. Range is 1-125.
Press ENTER to store the new value.
