5.2 Principle of operation
5.2.1 The oprinciple of the pH meter operating is based on the direct potentiometric
method for the activity determination of hydrogen ions in the test liquid while the
measuring the electromotive force (EMF) of the electrode system (ES), formed by the
measuring electrode and reference electrode immersed in a tested liquid.
The pH meter provides the measurement of the analyzed liquid temperature (T) by
applying the converting the thermometer resistance to a temperature resistance according
to the nominal static characteristic (NSCH).
The pH meter allows to provide the measurement of the liquid flow rate (V) by
applying the converting the frequency pulse signal of the flow sensor.
In the calculation of pH the influence of temperature on the pH-electrode
sensitivity is considered.
In general, the pH of the tested environment is calculated by by the formula:
pH =− E−EИ
0,1984×S
100 %×(273,15+to)
+pH И
,
where рН – the measured pH value of the analyzed environment;
Е– EMF value on the ES output, mV;
tº – the measured temperature value (by the resistance thermometer
automatically (ATC)) or specified manually (RTC)°С;
рНи– the coordinate of the isopotential point of the pH electrode;
Еи– the coordinate of the isopotential point of the pH electrode, mV;
S– the slope of pH electrode, %
The compensation of pH temperature dependence of the ultrapure water (UPW) is
carried out according to the procedure МУ 34-70-114-85.
5.2.2 EMF measuring between the ES electrodes is produced by the differential
switching circuit. In this scheme, the analyzed liquid should be grounded (Appendix C).
5.2.3 ORP measuring, in millivolts, is made with a pH meter, as a high-resistance
millivoltmeter, in a direct voltage mode measurement - "ORP mode."
In general, the ORP of the tested environment is calculated by by the formula:
where ORP – ORP measured value of the analyzed environment, mV;
Е– EMF value on the ES output, mV;
ЕСМ – the displacement of ES characteristics of the ORP electrode, mV;
S– the slope of ORP electrode, %
5.2.4 For the measuring the redox potential (ORP) the electrode system is used,
consisting of a redoxometric (platinum or gold) measuring electrode and a silver chloride
reference electrode.
5.2.5 The temperature by the measurement of ORP is not considered.

Herewith is only one digital output with switching settings = 100 V, 150 mA available
(see Figure C.3).

Herewith are four digital outputs with switching parameters ~240 V, 3 A available (see
Figure C.1).
8.3.2.5 LEDs
In this mode, for each of the four LEDs on the front panel of the analyzer the following
functions are set: response value, response function and binding to the parameter. For the
mounted pH-meter the binding to the parameter "Relay condition" is off.
Note - Each LED can be set to the easure ent error alar . To do this, select the ode: Binding
to the para eter, easure ent error (paragraph 8.3.6.). In this case the LED is flashing.

In this mode, the parameters of two current outputs are set.
Current outputs → Output 1 - setting the parameters of the first current output:
– Binding to the parameter - in this mode one of the five measured parameters,
which will be on the output current signal, is selected (See figure);
– Lower measurement limit - the lower limit value of the selected parameter is set.
– Upper measurement limit - the upper limit value of the selected parameter is set.
– Current output range - one of the options of the current output range is selected:
(0 ... 5) mA (0 ... 20 mA) or (4 ... 20 mA).
Current outputs → Exit 2 - setting the parameters of the second current output.
The parameters of the second current output are configured similarly to the setting the
parameters of the first current output.
8.3.2.7 nterface
In this mode, the interface parameters are set: network address, transfer rate and a parity
check.
8.3.2.8 Date and time
In this mode, the current year, month, day, hour and minute for the integrated real-time
clock are set.

In this mode, the sound alarm is set:
– On the button pressing - when this mode is on the beeps are audible by pressing
the buttons on the front panel of the pH meter.
– On errors (alarm) - when this mode is on, the sound signal is activated (intermittent
audible alarm), if a diagnosed pH meter error appears.
8.3.3 ARCH VE sub-menu
In this mode the viewing and configuration of the archive display is made. (See section
8.2).
– View Archive - in this mode the archive is displayed. Right button } allows to
switch the control cursor mode: я and ч or a time discrete interval will be changed
or cursor indicating the time of viewing and the values of the measured parameters at
this time moves (See Figure 1).
– Trend line N1 - in this mode a parameter with a continuous line will be displayed.
– Trend line N2 - in this mode a parameter with a broken line will be displayed.

8.3.5 Software version
In this mode, you can view the software version of "PH" set in this pH meter:
8.3.6 D AGNOST CS. In this mode it is possible to read the errors diagnosed with a
pH meter:
- Internal error 1;
- Internal error 2;
- No connection to БВД8 (for wall design only);
- defective temperature sensor. 1 (2).
If no error the message will be displayed: No errors were detected
8.3.7 First channel calibration
Pressing я-key the pH meter switches to the electrode system calibration mode
connected to the first channel of the pH meter. Calibration is performed on pH (ORP)
buffer solutions.
