1.1 System Description
The AX400 Series pH/Redox (ORP) analyzers and associated
electrode systems have been designed for continuous
monitoring and control of pH and Redox (ORP). The electrode
system can be standardized to the analyzer using the built-in
calibration facility and a single point buffering facility provides
easy re-calibration after initial standardization.
The analyzer is available in wall-/pipe-mount or panel-mount
versions with either one or two programmable, pH or Redox
(ORP) input channels, each with its own associated temperature
input channel. When making temperature compensated
measurements, the sample temperature is sensed by a
resistance thermometer (Pt100, Pt1000 or Balco 3K) mounted
in the electrode system.
The analyzer can be configured for and connected to either a
standard pH input (single, high impedence input >1013Ω) or
differential pH input (dual, high impedence inputs, both >1013Ω).
Differential pH input is designed for use with pH electrode
systems that incorporate a solution earth (ground) rod. The
measuring electrode and reference electrode signals are
measured separately using two, high impedence amplifiers and
compared with the solution earth (ground) potential. The
difference between the results is the value used for the pH
measurement.
All models incorporate a wash facility for system cleaning; the
alarm 3 relay can be configured to control the wash system
either automatically or manually. The relay can be programmed
to deliver either a continuous or pulsed signal to control an
external power supply to a solenoid or pump and the frequency,
duration and recovery time for the wash cycle are also
programmable. During a wash cycle, the analog output value is
held in its pre-cycle condition.
Analyzer operation and programming are performed using five
tactile membrane keys on the front panel. Programmed
functions are protected from unauthorized alteration by a four-
digit security code.
1 INTRODUCTION
1.2 AX400 Series Analyzer Options
Table 1.1 shows the range of configurations that are possible for
the AX400 Series analyzers. The analyzer automatically detects
the type of input board fitted for each input and displays only the
frames applicable to that input board type. If no input board is
fitted for Sensor B input, Sensor B frames are not displayed.

2.1 Powering Up the Analyzer
Caution. Ensure all connections are made
correctly, especially to the earth stud – see Section 6.3.
1) Ensure the input sensor(s) is/are connected correctly.
2) Switch on the power supply to the analyzer. A start-up
screen is displayed while internal checks are performed,
then the Operating Page (see Section 2.3) is displayed as the
pH or Redox (ORP) monitoring operation starts.
2.2 Displays and Controls – Fig. 2.1
The display comprises two rows of 41/2digit, 7-segment digital
displays, which show the actual values of the measured
parameters and alarm set points, and a 6-character dot matrix
display showing the associated units. The lower display line is a
16-character dot matrix display showing the programming
information.

Note. When Probe Type for either sensor (Sensor A only if single-input) is set to
Redox or ORP, this section is applicable only if Enable Cals. for that sensor is set to Ye s –
see Section 5.3.
Sensor Calibration Security Code
Enter the required code number (between 0000 and 19999), to gain access to the sensor
calibration procedure. If an incorrect value is entered, access to subsequent calibration
pages is prevented and the display reverts to the SENSOR CAL. page.
Note. Applicable only if Alter Cal. Code is not set to zero – see Section 5.7.
