200 Monitor Instruction Manual
2 Introduction
2.1 General
The 200 Monitor is used for processing and displaying the output signal from a Partech sensor. It combines a clear
display of the measured parameter, a simple user interface, with good flexibility to enable configuration to satisfy the
users needs. For remote signalling the 200 has two alarm outputs and a single analogue output.
The 200 Monitor has an IP65 enclosure and is suitable for outdoor use however a protective cover or outer enclosure
is recommended to further protect the instrument from the elements.
2.2 isplay
The 200 display indicates the measured value with large numerals for good visibility with an additional status line that
shows the current state of the alarm outputs, analogue output and any faults that are present. The display has a
backlight to enable use of the monitor in low light conditions and also has a user settable contrast.
The measurement title, units and display range can all be user set to suit the sensor being used and the parameter
being monitored.
2.3 Key Pad
A six key tactile membrane keypad is used for all configuration and operation of the 200 Monitor, each key has a very
positive operation enabling use even whilst wearing gloves.
2.4 Alarms
Two user configurable alarms are provided within the 200, which can be used to signal high, low or fault alarm
conditions. Each alarm output is a single pole change over relay which is normally energised (no alarm present) and
de-energises when an alarm occurs (fail safe).
2.5 Analogue Output
The 200 Monitor has a single analogue output that can be configured for voltage or current operation and can be set
to operate over the whole measuring range or a portion of the measuring range. The output can also be configured for
reverse operation (i.e. 20 to 4mA) should this be required.
When a fault condition occurs (see faults), the user can select whether the output indicates the last valid
measurement, its maximum output value or its minimum output value. This is useful when the alarm outputs are not
used and it is necessary to remotely determine the instrument’s state.
2.6 Sensors
The 200 Monitor can be used with the following Partech sensors:
TT Series TT2000LA, TT2000LS, TT2i, TT10i, TT12i, TT20i
IR Series IR8, IR15, IR40, IR100, IR12LS
IL Series IL55, IL55BV2
ST Series ST20 Range 0-xxxxx

4 MCERTS Product Certification
Increasingly, with 'Modern Regulation' and in order to strengthen its auditing of operators' self-monitoring
arrangements, the Environment Agency is moving towards more efficient regulation through Operator and Pollution
Risk Appraisal (OPRA), Operator Monitoring Assessment (OMA) and it's Monitoring Certification Scheme (MCERTS)
MCERTS is now well established and is seen as a mark of quality. It provides a framework within which environmental
measurements can be made in accordance with the Agency's quality requirements. The scheme covers a range of
monitoring, sampling and inspection activities including product certification. Partech Instruments manufacture and
supply the first certified Turbidity Monitoring System under the Environment Agency's MCERTS scheme for
Continuous Water Monitoring equipment (CWM's).
The current performance standard for CWM's is available at:

5 Installation
5.1 Location
The field mounting version of the 200 Monitor is housed in an IP65 enclosure and therefore is suitable for mounting
outdoors, preferably located close to the sensor. It is advisable to mount the monitor in a location where it has some
protection from the elements, this could be inside a GRP or metal cabinet, in a control room, or with a protective
shield.
It is recommended that the monitor is located close to the sensor to simplify the set up and calibration of the system
thus avoiding long walks between monitor and sensor.
Note: The maximum length of cable between the monitor and sensor is 100 metres.

200 Monitor Instruction Manual
6 Basic Operational
6.1 Measure Mode
The normal operating mode for the 200 Monitor is its measure mode and this is active when the measured value is
displayed in large numbers. Whilst in measure mode the display value is continually updated based upon the current
sensor input signal.
The display in measure mode also includes a status bar that scrolls through the status of the alarm and analogue
outputs and if the instrument is locked. The status bar is also used to indicate any instrument faults that are present.
During a clean cycle the status bar indicates the current stage of the clean cycle.
6.2 Measurement Cycle
The measurement cycle is carried out in the background at all times when the instrument is switched on regardless of
whether the instrument is in measure mode or not. It is therefore capable of updating the output signal and alarms
when the user is navigating the menu structure in order to change the instrument configuration. The monitor performs
five measurement cycles per second enabling a response time of one fifth of a second (Damping rate set to Instant –
see damping).
6.3 isplay
The resolution of the displayed value is determined by the sensor range setting such that only sensible display values
are indicated, the same range also determines the calibration value range, alarm value range, and analogue output
range.
The display units and measurement title is user selectable and should be chosen to suit the parameter being
monitored and sensor being used.

200 Monitor Instruction Manual
7.2 ata Entry
To provide the user with a simply interface, the 200 uses three methods of data entry for the setting of all the user
configurable parameters. The various methods of user data entry used on the 200 are described below:
7.2.1 User List Selection
This method of user data entry is used when a selection from a predefined list of option is required such as sensor
type, display range and backlight mode. The list of possible selections will be displayed and a small tick will identify the
current setting. If the list contains more than five items, small UP and OWN arrows will appear on the display to
indicate there are more items than that displayed. To make a selection, the selector bar can be moved using the
keys, to select the required item. Pressing the OK key will select the highlighted item and a small tick will appear next
to it. Pressing the MENU key will exit the list selection menu.
7.2.2 User Value Entry
When a numerical value is to be set, the current value will be displayed with a flashing cursor. The range of
adjustment of the value is predefined and therefore only values within this range can be entered. To adjust a value, the
keys are used to select a digit and the keys are used to increment/decrement the digit. When the new value
has been set pressing the OK key will store it and exit from the value adjustment display. If the MENU key is pressed
any changes that have been made will be lost and the value adjustment display will be exited.

200 Monitor Instruction Manual
8 Calibration
8.1 Calibration General
Calibration of the 200 Monitor is very important, errors in the calibration process will affect the measurement
performance of the instrument. The following section describes the various aspects of calibrating the 200 Monitor and
has been written with the understanding that the user has knowledge of the measurement being made.
When a new system is installed, a period of 4 hours should be allowed for the equipment to stabilise before calibration
commences. This is to enable the system to adjust to the “new” ambient conditions. This should not be considered as
a warm up time from power up, it allows the system to adjust from a warm store or office to a cold site.
Any containers used to store calibration samples should be cleaned prior to use. This is particularly important when
performing the zero point calibration on a low range sensor.
The most accurate method of calibration is using a primary standard, i.e. calibration in the actual solution against a lab
result. Where this is not possible or where the trend of the reading is necessary rather than an absolute value it is
acceptable to use a secondary standard.
Please read this section together with the section titled ‘Calibration – Equipment and Procedures’ found in the
instruction manual for the chosen sensor.
Note: Whenever the sensor type is changed, the factory default values for calibration are loaded for the new
sensor type.
8.2 Methods of Calibration
Primary Standard
This method of calibration will give the best results however it does require the use of a laboratory to carry out a
gravimetric analysis of the calibration solution. The result of the gravimetric analysis is used as the calibration value.
Secondary Standard
In cases where it is not possible to carry out calibration using a primary standard, secondary standards such as Fullers
Earth or Formazin can be used. It is important to remember however that instruments calibrated in this way will give
results based on the secondary standard used and this will differ from the results of a gravimetric analysis.
A guide to the preparation of Fullers Earth and Formazin solutions is located at the back of this manual.
Calibration Intervals
The 200 Monitor and Sensor combination once calibrated will require calibration checking/re-calibration at 3-6
monthly intervals, however this does depend on the application. The calibration of the instrument can be effected by
seasonal variations in the measured effluent, however only knowledge of the application can determine the re-
calibration interval required.
8.3 Preparing for Calibration
To ensure that calibration will be as successful as possible the following should be observed:
•Clean the whole sensor and at least 1 metre of cable.
•The zero solution should be clean settled tap water for high range sensors and freshly distilled or de-
mineralised for low range sensors.
•A calibration solution will be required; ideally this should be greater than 5% of the intended measurement
range.
16 300IM-Issue 12 Issue Date 14/10/2014 Page 1 of 50

200 Monitor Instruction Manual
8.4 Calibration Wizard
The 200 calibration wizard guides the user through the important process of calibrating the instrument. When the
equipment is first installed, the setup wizard should be used to ensure that all the essential settings have been
properly set. Once the setup wizard has been completed, the instrument should respond to changes to the sensor
signal (for example placing the sensor into the zero solution and then into the calibration solution). Although the
instrument is responding, the factory default calibration values are used until user calibration is carried out.
Before using the calibration wizard, the guideline described in the preparation for calibration section above should be
observed.
Cal Wizard Keys
Once the calibration wizard has been entered, the MENU key can be used to exit at any time. Pressing the key
moves forward to the next step and pressing the moves back to the previous step. Pressing the OK key will activate
the displayed activity.
Cal Wizard Stages
The Cal Wizard guides the user through the process of setting the instrument zero and span. For more information
about setting zero and span, refer to the applicable section of this manual.
8.5 Set Zero
This menu is used to set the instrument display zero for the attached sensor. To zero the instrument, go to the
Calibration menu, select Set Zero and press the OK key. Immerse the sensor into the zero solution and press the OK
key. The 200 Monitor collects data for the zeroing operation for approximately 5 seconds to ensure that the zero is
set accurately. During this period do not move the sensor, as this could effect the zero operation. If the zeroing
process is successful, the monitor will return to measure mode and the display value will be zero. If a problem occurs
during the zeroing operation, an error message will be displayed and the monitor will return to the Calibration menu.

Calibration Wizard

200 Monitor Instruction Manual
8.6 Set Span
The Set Span function is used to set the calibration point for the instrument, which is used in the calculation of the
displayed value. To calibrate the instrument, go to the Calibration menu, select Set Span and press the OK key.
Note: If an online calibration is being carried out, whilst in measure mode check that the display value is
stable – it may be necessary to increase the damping level top stabilise the display value.
Step 1. Calibration Value Entry
The calibration value can be set to a value between 10 – 100% of the currently selected measuring range using the
keys. This value should be set to the value of the calibration solution. Once the correct value has been set
press the OK key. Pressing the MENU key will exit the Set Span operation.
Note: The calibration value can only be set between 10 –100% of the display range.
Step 2. Calibrating
As indicated by the on display instructions, immerse the sensor into the calibration solution and press the OK key. The
200 Monitor collects data for the spanning operation for
approximately 5 seconds to ensure that the span is set
accurately. During this period do not move the sensor, as
this could effect the span operation. If the spanning
process is successful, the monitor will return to measure
mode and the display value should be correct for the
calibration solution. If a problem occurs during the
spanning operation, an error message will be displayed
and the monitor will return to the Calibration menu.

8.7 Take Sample
The Take Sample and Enter Sample Result facilities are
provided to allow calibration to be carried out
retrospectively based upon stored information. An
example of this is where the value of the calibration
solution is not known at the time of calibration and an
estimated value was used to set the instrument span.
The take sample menu is used to store the sensor
signal in the calibration solution for later use.
From the Calibration menu, select Take Sample and press the OK key. With the sensors immersed in the calibration
solution, (The display value must be stable – this can be checked when in measure mode) press the OK key. The
200 Monitor collects data for the take sample operation for approximately 5 seconds; during this period do not move
the sensor. If the take sample process is successful, the monitor will return to measure mode. If a problem occurs
during the zeroing operation, an error message will be displayed and the monitor will return to the Calibration menu.
8.8 Enter sample Result
When the take sample operation has been carried out, and the correct value for the calibration solution is known, the
new calibration value can be entered using the Enter Sample Result menu.
To enter the new calibration value, from the calibration menu, select the Enter Sample Result menu and press the OK
key. The calibration value can be set to a value between 10 – 100% of the currently selected measuring range using
the keys. This value should be set to the value of the calibration solution. Once the correct value has been set
press the OK key. Pressing the MENU key will exit the Set Span operation.
Note: The calibration value can only be set between 10 –100% of the display range.
