750w² Monitor Instruction Manual
1 Introduction
1.1 General
The 750w² Monitor is designed to work with Partech’s WaterWatch² (w²) sensors.
It com ines a clear display of the measured parameter, a simple user interface,
with good flexi ility to ena le configuration to satisfy the users needs.
1.2 Display
The 750w² display indicates the measured value with large numerals with an
additional status line that shows the current settings, attery status and any faults
that are present. The display has a acklight to ena le use of the monitor in low
light conditions and also has adjusta le contrast.
The measurement title and units can all e user set to suit the sensor eing used
and the application eing monitored.
1.3 Keypad
The 7 key tactile mem rane keypad is used for all configuration and operation of
the 750w² Monitor.
1.4 Sensors
The 750w² Monitor can currently e used with the SoliTechw² IR sensor range.
1.5 Manual Conventions
This instruction manual descri es the configuration and operation of the 750w²
Monitor and where required includes some information regarding sensors. It is
therefore very important that it is used in conjunction with the relevant sensor
instruction manual.
The manual has een written on the asis that the user has a asic knowledge of
instrumentation and an understanding of the type of measurement eing made.
Training in the use of the 750w² Monitor can e provided y Partech, please
contact Partech for further information

750w² Monitor Instruction Manual
3.2.2 User Value Entry (Figure 8)
When a numerical value is to e set, the current
value will e displayed with a flashing cursor. The
range of adjustment of the value is predefined and
therefore only values within this range can e

digit and the  keys are used to increase/decrease the digit.
When the new value has een set pressing the OK key will store it and exit from
the value adjustment display.
To exit without saving changes press the MENU key.
3.2.3 User Text Entry (Figure 9)
Using this method of data entry, the user is a le to
enter or edit text and is used for user defined
measurement title and units.
The text string is displayed with a flashing cursor
indicating the selected character.
The  keys are used to select a character, and the  keys to change the
selected character.
When all changes are complete press the OK key to store the text.
To exit without saving changes press the MENU key.

6 Recorded Data
The recorded data function allows 750w² monitor display
access to the saved snapshot sensor readings recorded y
pressing the OK key in ‘Measure Mode’. (Figure 25)
Each individual record consists of (Figure 26):
DATE / TIME
MEASUREMENT TITLE
VALUE / UNITS .
The records are displayed with the newest first (at the
ottom of the display). Using the  keys will scroll through the records.
6.1 Data via USB
When the 750w² Monitor is plugged into a PC it will appear like a USB memory drive
named “750w2” with a folder “DataRecordings”.
Inside this folder will e a CSV file named “DataRecordings”, this is a file that com ines
all the recorded data and is used for data display on the monitor. Editing this file may
corrupt your data.
The folder will also have files that are specific to each sensor that is used, it is
advisa le to copy this file to your desktop efore using it to import that data into a
spreadsheet for analysis.

7 Batter Charging
7.1 Battery
The monitor contains a Nickel Metal Hydride (NiMH) attery pack that supplies
the power for operation. This type of attery does not have to e fully discharged
prior to charging, although this is a preferred option. It is therefore possi le to "top
up" the attery charge as and when required, this is particularly useful prior to the
instrument eing used for a long period.
Battery life is sufficient for 1 week normal use etween charges
•When normal use is defined as 30 measurements per day
•Under normal operating conditions. e.g. normal contrast and rightness
settings, Auto shutdown ena led meaning 750w² on for only one minute
at a time.
7.2 Charger
The 750w² Monitor is supplied with a USB power adapter and ca le. This is
plugged into the socket on the ottom left of the 750w² monitor (Figure 27). This
device is specifically designed to provide the optimum conditions for the 750w²
attery. However, a variety of USB charge sources can e used as long as they
meet the minimum 500mA charging current.
When connected to the monitor, the charging LED gives a visual indication of
charging status (Figure 27).
LED key:
Unlit – not connected or charger off
Red – Charging
Green – Fully charged
