Did you know ?
In chemistry, an alkali is a basic, ionic salt of an alkali metal or alkaline earth metal element. Alkalis are best known
for being bases (compounds with pH greater than 7) that dissolve in water. The adjective alkaline is commonly used
in English as a synonym for base, especially for soluble bases. This broad use of the term is likely to have come about
because alkalis were the first bases known to obey the Arrhenius definition of a base and are still among the more
common bases. Since Brønsted-Lowry acid-base theory, the term alkali in chemistry is normally restricted to those
salts containing alkali and alkaline earth metal elements.
An acid (often represented by the generic formula HA [H+A−]) is traditionally considered any chemical compound that,
when dissolved in water, gives a solution with a hydrogen ion activity greater than in pure water, i.e. a pH less than
7.0. That approximates the modern definition of Johannes Nicolaus Brønsted and Martin Lowry, who independently
defined an acid as a compound which donates a hydrogen ion (H+) to another compound (called a base). Common
examples include acetic acid (in vinegar) and sulfuric acid (used in car batteries). Acid/base systems are different
from redox reactions in that there is no change in oxidation state.
10
8.3 “Set-Point”, pH (proportional)
This mode is valid for “CH1 PH PULSE 1” and “CH1 PH PULSE 2” outputs.
Proportional mode set the instrument to operate using a calculated percentage between two set values that
enable or disable the pH pump. To use this mode move cursor on “Working Mode”. Press the wheel and select it.
PROPORTIONAL mode between 7pH(0 P/m) and 8pH (180 P/m). p/m is : pulses per minute
In this mode the pH pump will be “ON” for values greater than 8pH with maximum set pulses per minute capacity
(e.g.: 180) and it’ll be “OFF” for values lower than 7pH. For values of 7.5pH pump will be “ON” with 90 pulses
per minute capacity. The calculation is based on 180 pulses per minute setting (see page 22). To end procedure
move cursor on “OK” and press wheel to proceed to “Save” request screen. Move wheel on “YES” to save or
“NO” to discard changes.
11
8.4 “PWM” (proportional), pH
This mode is valid for “CH1 PH RELAY” output only. Pulse-width modulation (PWM) of a signal or power source
involves the modulation of its duty cycle, to either convey information over a communications channel or control
the amount of power sent to a load.
This mode works over a settable (0 to 100 seconds) time to switch on or off selected output.
During this time if reading value will move towards a set value (on or off) the PWM will operate the output on
timered basis. Reaching the set value the PWM will permanently leave on or off the output.
Parameters to set for this mode are:
Unit Value + %: (time activity towards set value. 0% means 0 seconds. 100% means 100 seconds.)
pH range: two pH values within PWM operates.
For example: set first pH value at 8.00 = 100% and second pH value at 4.0 = 0%.
For reading values * to 8.00 the output will be permanently ON.
For reading values ) 4.0 the output will be permanently OFF.
For reading value of 7.00 the output will be OFF for 25 seconds, ON for 75 seconds.
For reading value of 6.00 the output will be OFF for 50 seconds, ON for 50 seconds.

8.5 “PWM” (fixed), pH
This mode is valid for “CH1 PH RELAY” output only. Pulse-width modulation (PWM) of a signal or power source
involves the modulation of its duty cycle, to either convey information over a communications channel or control
the amount of power sent to a load. Using fixed mode is possible to set operating time to switch on or off selected
output.
During this time if reading value will move towards a set value (on or off) the PWM will operate the output on
timered basis. Reaching the set value the PWM will permanently leave on (for selected amount of time) or off the
output.
Parameters to set for this mode are:
pH range: two pH values within PWM operates.
Ton: ON period, during output activity.
Toff: OFF period, during output activity.
For example: set first pH value (OFF) at 7.20.. Set second pH value (ON) at 8.00.
Set “working-pause” output activity with Toff 0 seconds and Ton 40 seconds.
For reading values * to 8.00 the output will be ON with activity based on Ton and Toff.
For reading values ) 7.20 the output will be permanently OFF.
For reading values within working range operating mode is on HYSTERESIS base. Once reading value is 7.20 pH will be permanently off until it will
reaches 8.00 pH.

This mode enables Conductivity pump to operate between two On/Off values. Move wheel over “Working
Mode” to select it.
ON/OFF mode
Set Conductivity value at 1,50mS ON and 2,00mS OFF. The difference between the two Conductivity values is called
HYSTERESIS.
Instrument will enable the Conductivity pump when reading value will decrease at 1,50mS
At 1,50mS the Conductivity pump will be enabled until reading value will increase at 2,00mS.
Pulse Speed: pulses per minute setting.

8.8 “Set-Point”, Conductivity (proportional)
“CH2 MS PULSE” output can be set into this mode.
Proportional mode set the instrument to operate using a calculated percentage between two set values that
enable or disable the Conductivity pump. To use this mode move cursor on “Working Mode”. Press the wheel
and select it.
PROPORTIONAL MODE between 2,00(0 P/m) and 1,50(180 P/m). [P/m: pulses per minute]
This mode operates Conductivity pump for a value lower that 1,50mS with maximum dosing capacity (180strokes) and
it will stop Conductivity pump for a reading value higher than 2,00mS.
A 1,75mS reading value will operate Conductivity pump with a 90 strokes capacity calculated on strokes settings (see
page 22). Pump will operare with 90 strokes dosing capacity. To end procedure move cursor on “OK” and press wheel.
Choose “SAVE” to save setup or “NO” to discard changes.

8.9 “PWM” Proportional, Conductivity
“CH2 MS RELAY” output can be set into this mode.
Pulse-width modulation (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey
information over a communications channel or control the amount of power sent to a load.
This mode works over a settable (0 to 100 seconds) time to switch on or off selected output.
Time resolution is 5 seconds, 5 steps. During this time if reading value will move towards a set value (on or off) the PWM
will operate the output on timered basis. Reaching the set value the PWM will permanently leave on or off the output.
Parameters to set are:
Unit Value + %: (time activity towards set value. 0% means 0 seconds. 100% means 100 seconds.)

What is a static IP address/dynamic IP address?
A static IP address is a number (in the form of a dotted quad) that is assigned to a computer by an Internet service provider (ISP)
to be its permanent address on the Internet. Computers use IP addresses to locate and talk to each other on the Internet, much the
same way people use phone numbers to locate and talk to one another on the telephone. When you want to visit whatis.com, your
computer asks a domain name system (DNS) server (think telephone information operator) for the correct dotted quad number
(think phone number) for whatis.com and your computer uses the answer it receives to connect to the whatis.com server.
It would be simple if every computer that connects to the Internet could have its own static IP number, but when the Internet was

IP numbers to go around. To get around that problem, many Internet service providers limit the number of static IP addresses
they allocate, and economize on the remaining number of IP addresses they possess by temporarily assigning an IP address to

called a dynamic IP address.
Requesting DHCP computers receive a dynamic IP address (think temporary phone number) for the duration of that Internet sesVLRQRUIRUVRPHRWKHUVSHFL¿HGDPRXQWRIWLPH2QFHWKHXVHUGLVFRQQHFWVIURPWKH,QWHUQHWWKHLUG\QDPLF,3DGGUHVVJRHVEDFN
into the IP address pool so it can be assigned to another user. Even if the user reconnects immediately, odds are they will not be
assigned the same IP address from the pool. To keep our telephone telephone analogy going, using a dynamic IP address is similar to using a pay phone. Unless there is a reason to receive a call, the user does not care what number he or she is calling from.
There are times, however, when users who connect to the Internet using dynamic IP wish to allow other computers to locate them.
Perhaps they want to use CU-SeeMe or use a VoIP application to make long distance phone calls using their IP connection. In that
case, they would need a static IP address. The user has two choices; they can contact their ISP and request a static IP address, or
they can use a dynamic DNS service. Either choice will probably involve an additional monthly fee.

Appendix - “Temperature compensation”
Conductivity measurements are temperature dependent. The degree to which temperature affects conductivity varies
from solution to solution and can be calculated using the following formula:
Gt = Gtcal {1 + a(T-Tcal)}
where: Gt = conductivity at any temperature T in °C, Gtcal = conductivity at calibration temperature Tcal in °C, a =
temperature coefficient of solution at Tcal in °C.

Common alphas (a) are listed in the table above. To determine that (a) of other solutions, simply measure conductivity
at a range of temperatures and graph the change in conductivity versus the change in temperature. Divide the slope
of the graph by Gtcal to get a.
Temperature compensation (Alpha) can be changed within 0.0% and 5.0%. It should be set according to measured
chemical properties. If a temperature probe is installed choose “Enable” for “Automatic”. Otherwise select “Disable”
and enter a temperature value in “Temperature” field.
Note: “Temperarure” field is not visible if “Automatic” has been set on “Enable”.
To enable pH
compensation change
value from “NO” to
YES”.
To end procedure move cursor on “OK” and press wheel to proceed to “Save” request screen. Move wheel on
“YES” to save or “NO” to discard changes.
