Operating for the first time
Once the software has been installed you will be asked to enter a password.
This password is used if you decide to enable the security facilities that are
turned off off off off by default. Enter a password and make a note of it.
Configuration
Once a password has been entered you will be presented with the configuration
window. Select the “device” tab:
Select the correct logger type by clicking on one of the three buttons.
Select the correct interface to connect the logger to the computer and make
sure the port name matches the same port that you are going to connect the
reader to.
The Graph tab contains the functions that will determine how the data is
presented. For TempIT-Pro users use the tree view to enable “Time above
temperature”, FO, AO, and PU calculations.
The Calibration tab lets you specify when to display the calibration
reminder for the data logger. By default, this value is set to 12 Months.
Every time the data logger is issued, TempIT will check to see if the data
logger requires calibration. If the data logger requires calibrating, the
software will warn you of this but not stop you from using the data logger.
The Calibration tab also contains the Passcode. This is not to be confused
with the password entered when the software was started for the first time.
The passcode is used to ensure only authorized versions of the software can
issue the data logger. Unless you are intending to use the passcode facility,
we strongly suggest you do not alter this number. If you do change the number
please ensure you take a note of the new number.
Click on the OK button to close the configuration window. Connect the
reader/interface lead to the computer. Place the data logger on or in the
communication interface/reader.
The type of interface depends on the model being used. The SL50 series button
loggers need to be clipped into the interface with the etched face down. The
SL5XUSB data loggers are self contain do not require any additional interface
leads or readers. The SL150 series data loggers should be placed on the reader
in any orientation. The SL7000 series data loggers use a conventional USB
lead.
Issuing the data logger The process of setting up the data logger is called
issuing. During the issuing process you can specify how often the data logger
takes a reading. You can specify alarm levels that appear on the graphs. These
alarm points activate the alarm lights on the data loggers that have visible
alarms.
Click on the issue logger button:
Or, select “Issue Logger” from the “Logger Operations” menu.
Tempe will now communicate with the data logger and if communication is
successful you will be presented with the data logger issue screen.
The first tab is the General Setup tab. In the general setup tab you can give
the data logger a 9-digit identification number. You can use this to identify
individual loggers if you have more than one.
You can also set the sample rate in this tab. The sample rate is the time
between readings. The four boxes above the sample rate show when the logger
will be issued and when the memory will become full. As you change the sample
rate, you will notice the time and date when the logger becomes full also
changes. Ensure you choose a sample rate that allows enough time for whatever
you are monitoring.
Some data loggers allow you to specify what happens when the memory is full.
There are two options:
Stop When Full – In this mode, the data logger will stop taking readings when
the memory is full. Anything that happens to the data logger after this point
will not be recorded. Wrap When Full – In this mode, when the memory is full,
the data logger will throw away the oldest reading and then take a new
reading. Providing you with a rolling window. Please note, once the oldest
reading has been deleted, it is permanently lost. In either case, issuing the
data logger clears the stored data.
The next tab is the Alarm / LED Blink tab. This is where alarm levels are
entered. You can also enter a time period that the alarm condition can exist
for before the alarm is actually tripped.
For data loggers with visible and audible alarms, you can also determine how
often they flash/beep. The shorter you have these parameters, the more effect
you have on the battery life of the product. Try to keep these as long as you
can.
The Delayed Start tab is used for specifying an exact time and date when
the data logger should start taking readings. If this feature is disabled or
not available, the data logger will start taking readings as soon as it is
issued. Not all data loggers support the delayed start feature.
The Manifest Text tab allows you to enter a few lines of text that
describe what you are monitoring. This could be a batch number, the name of
the product being measured or even the registration number of a vehicle. You
can of course leave these fields empty.
The Engineering tab is used to configure the process (mA or Voltage) input
data loggers. In this tab, the scaling is entered to convert the process input
to real engineering units.
Click on the “Issue Logger” button. You will now be presented with a summary
window that will explain all of the options you have chosen. If you are happy
with this, click on the “Accept Settings” button. Clicking on the Cancel
button will take you back to the issue screens.
The software will then configure the data logger as per your instructions and
logging will start – unless you have used the delayed start option, in which
case, logging will start at the time you specified. Please note, issuing the
data logger erases any stored information.
Retrieving Stored Data
The process of getting the stored data from the data logger is called
“reading” the data logger. This can be started from the “logger operations”
menu or by clicking on the read logger icon:
Place the data logger on to or into the reader and click on the read logger
icon. All the stored data within the data logger will be transferred to the
computer and presented as a graph. The information is still in the data logger
until the data logger is re-issued. Remember, if wrap when the full memory
option is used, the oldest reading is lost when a new reading is taken.
Viewing Data
Once the data have been read from the data logger the information is presented
as a graph of the measured parameter against time. If the Pro version of the
software is being used, you can also see the data in a tabular format.
You can now analyze the data by moving the cursor around the screen. The area
immediately above the graph shows the value and data and time of the cursor
whilst in the graph area. It is possible to zoom in to a particular part of
the graph by holding down the left button on the mouse and dragging a square
around the area you wish to see in more detail.
Tempe-Pro
Tempe-Pro is available in two formats. The first is using a USB key. When the
key is present in the USB slot on the computer, the Pro functions are enabled.
The second option is a “single machine license”. To upgrade to TempIT-Pro you
need to obtain a license key from your supplier. As Tempe-Pro will only work
on the computer it is registered for, you must supply your supplier with the
“Unique Machine Key”. This can be found in the Help menu under License. Your
supplier will then be able to give you the License key for you to enter. Tempe
will then restart as the Pro version.
In the Pro version of the software you have the following additional
functions:
- View data in a tabular format
- Export data to a spreadsheet in txt or csv format
- Overlay multiple files into one graph.
- Calculate mean kinetic temperature (MKT)
- Calculate Ao • Calculate Fo
- Calculate PU
- Time Above Temperature Test (Pass/Fail)
- Add Comments to the graph
- Change descriptor function
To view the data in a tabular format, click on “show table” in the control panel on the left-hand side of the screen. Clicking on “hide table” will revert back to the default graphical view. You can resize each window by a left click and hold on to the bar that separates the windows. Right-clicking your mouse on the main graphing area allows you to change the graph descriptor – an area under the serial number that can be used to describe what is happening in the graph below. Right-clicking in the main view also provides the facility to add comments and arrows. Once you have added a comment, you can move the comment by single clicking and holding down the left-hand mouse button. The arrowhead is moved by double-clicking and holding down the mouse button.
FO and AO Calculations
FO is the sterilization time to ensure that whatever microorganisms are
contained within the process sample are reduced to an acceptable limit.
Suppose that we are looking for a FO of 12 minutes i.e to obtain the required
Final Lethal Ratio the sample needs to be held at 121.11°C for 12 minutes. A
data logger is used to plot the actual sterilization cycle. With the graph on
the screen, click on ‘Show Measure’ on the control panel. Two vertical bars
appear that can be moved by clicking the cursor on them and then dragging. The
start bar should be placed at the start of the cycle, the right-hand bar can
then be dragged across the graph and the FO at the point of placement is shown
in the table. As you can see FO is in minutes and increases as the bar is
dragged to the right until the temperature falls below 90°C and when no
further sterilization takes place. (Note the FO value only updates when the
mouse click is released). When 12 Minutes is seen, the sample will have been
sterilized to the required level. This can be considerably less time than
waiting for the sample temperature to rise to 121.11°C and holding it there
for 12 minutes and allowing it to cool, thus saving time and energy and hence
costs.
AO is exactly the same as FO but in this case, instead of the equivalent
temperature being normalized to 121.11°C it is normalized to 80°C. This is
used in lower temperature systems such as washer sterilizers etc. You can also
email the graph as an image provided your computer has email facilities.
Once you have finished analyzing the data you can save the data for future
reference by clicking on the save icon.
For more detailed instructions, please refer to the manual supplied on the CD.
