Why Configure Kemio?
Tagging additional information to test results is useful
in applications that require reporting, performance
improvement, monitoring, and where instruments are used
in a variety of locations or to measure multiple parameters.
With all this information available over USB, the test does
not simply deliver a number on a screen, but gives context
to each result.
To manage labels, see p. 15.
To enable tagging labels see p. 28.
Create a user profile on the device for each person who will
perform tests. If other people will also perform tests less
frequently, consider creating a DEFAULT or OTHER user.
To manage users, see p. 19.
To enable tagging users see p. 28.
Data Enrichment
Labels are used to tag each test as one of a pre-defined
set. If labels are used, they should span all possible test
types.
Examples of label sets include:
• Types of produce in a vegetable processing facility
(carrots, lettuce, spinach)
Label
User

For high-risk applications that are audited or closely
monitored, Kemio offers the following options to improve
traceability.
Traceability
The Notes field can be used to suit any application need. It
can be structured as desired: to give contextual information,
environmental information, equipment details, a report on
corrective action taken, etc.
By using Kemio to tag the name of the user performing the
test to each test result. Scan a user ID barcode for strictest
traceability.
To manage users, see p. 19.
To manage users settings see p. 28.
Notes
Users To Improve Accountability
910
Reference codes are application-specific tags for a type of
measurement. Examples include:
• Sample points
• Location IDs
• Work orders
• Batches
• Variety of test
• etc.
This information can be tagged directly to each test result
from a printed barcode on paperwork, a barcode on a
label, a specially printed and laminated barcode, etc.
To generate a barcode, use an online barcode generator.
Standard barcode formats include UPC, EAN, Code 39,
Code 128, Code 93, Codabar, etc. All will be interpreted by
the barcode scanner. Type in the code. Print the code on
paper or a label or display it on a screen.
Barcodes for Kemio can be a maximum of 15 characters,
using the characters available on the Kemio keyboard. If
Kemio scans a character from outside the set, it simply will
not be stored in memory.
To enable scanning reference codes see p. 28.
Reference Codes
To ensure that the correct batch information for each sensor
is used on each test by forcing the user to scan each sensor
before use.
Batch Code Scanning

11 12
If a measurement is tagged with a label that has limits
set, the result will be presented as a PASS or a FAIL.
In the event of a PASS, the user can be confident in their
water quality. No action must be taken.
If the result is a FAIL, then the user must take some further
action. Kemio enables rapid decision making.
Once this action is taken, this and/or the root cause of the
problem can be documented in the Notes section of the
test and tagged to the FAIL result for future reference.
To manage labels and limits, see p. 15.
To enable tagging labels see p. 29.
Kemio corrects for dilution factors automatically. The
displayed result is calculated according to the dilution factor
which is programmed into the label, eliminating the need for
the user to do any calculation.
To manage labels and dilution factors, see p. 15.
To enable tagging labels see p. 29.
Process Control
Actionable Results
Dilution
To manage labels, see p.15.
To enable tagging labels see p.28.
To correlate with corrective action. By using labels with limits,
each test will either be a PASS or a FAIL. Every out-of-spec
result (FAIL) should have some corrective action. Failed
results can be monitored using the test history (p. 6) to
ensure that the process is being followed correctly.
See p.28 'Scanner Settings' to configure Kemio to require
users to scan the batch code every test.
See p.31 for details about batch codes.
Limits and Pass/Fail Results

Select a single target test parameter and unselect all
the others.
14
Disable tagging labels, users and reference codes.
When performing a test, Kemio will not prompt for a label
or user. After the test, the SCAN REFERENCE button will
not appear. In the log file, the label and user will always be
DEFAULT, and the limits and reference fields will be blank.
A second option is to delete all the user-generated labels
and users. Kemio will not ask for a label or user. In the log file,
the label and user will always be DEFAULT.
A third option is to keep Labels and Users selected, and set
exactly one label (with limits, if desired) and user. Since there
is only one choice, Kemio will automatically select it and display
it in the log.
Reduce the frequency of scanning sensor barcodes
Configure Kemio to scan the sensor batch only the first
test after Kemio is turned on. Or configure Kemio to
prompt users to select the batch from a list on the screen
instead of scanning.
To manage scanning settings, see p. 28.
To manage labels, limits and users, see p. 15.
To enable tagging labels, users and reference
codes see p. 29.
13
To manage test types, see p. 25.
For straightforward applications where little variance is
expected, Kemio can be configured in the simplest way to
reduce the number of steps for the user. This provides the
most direct route to a result.

4Add a lower limit and/or upper
limit to set the range that is
considered a PASS for the test
application.
If a sample measured using
this label has a concentration
outside of this range, it will be
tagged as a FAIL.
5
If the process requires dilution to bring the measured sam-
ple within Kemio’s measurement range, use a dilution factor.
If no dilution is required, the field can be left blank. If 1 or 0 is
entered for dilution, the label will display “- X” and no multi-
plication will be performed.
The displayed test result is calculated using the dilution fac-
tor programmed into the label.
For example:
A 100 mg/L sample needs diluting 4X. 1 part of sample
is diluted with 3 parts of deionized water. When a test is
performed using this label, the instrument will read 25 mg/L.
Using the dilution factor, 100 mg/L will be displayed on the
results screen.
6
Limits are applied to the calculated result. Press
SAVE to save the label in memory.
When configuring the label, if the test limits after dividing
by the dilution factor do not fall within the sensor method
test range, an error is displayed, and the label will not
close or save.

Batch Information
Kemio uses an electrochemical method with disposable screen-
printed and dosed sensors to measure chemicals in solution.
The single-use sensors produced in a single batch all have the
same performance characteristics
Calibration of each sensor batch is performed by Palintest
during production and the information is provided with the
sensors in the form of a QR code on the box.
The correct batch information must be used with a sensor. If
a sensor uses calibration information from the wrong batch, it
could produce a less accurate result. Kemio protects against
this possibility by encouraging the user to scan the batch code
to access the correct calibration batch for each test. If this
option is disabled, it introduces a possible user error.
For details on how to load batch information
before a test is performed, see p. 20.
Calibration/Validation
Labels
Set whether the SELECT LABEL screen appears at the start
of a test. If this is switched off, the label tagged to the result
will be DEFAULT and there will be no limits or dilution applied
to the test. This means that the results screen will always be
a blue result rather than a PASS or FAIL.
Reference
Set whether the SCAN REFERENCE button appears on the
Details page at the end of the test. If scanning a code is a
part of the workflow, set this switch on. If there is never a
code to attach to results, set this switch to off.
Scanner Settings
Kemio’s barcode scanner ensures that the right sensor type
is used for a test, that the right calibration information is
used, and that the sensor is in date
If an incorrect barcode is scanned, the instrument displays
an error screen with advice on how to correct the problem
and proceed with the test.
•Scan every test. Each time Perform Test is pressed, Kemio
will prompt the user to scan the sensor barcode. Select this
option for total traceability.
•First test only. After powering on, the first test of a test
type will be scanned. Until the instrument is turned off, Kemio
will skip the prompt to scan a sensor.
•Manual entry. Select the correct code from the list on
screen..

Data Log
The data log is a record of the over 10000 test results and
information. Each line represents a separate test result. A
test that produces multiple results is stored in the data log
under multiple lines.
The result log can easily be imported into analysis tools, such
as excel. Each line includes data in tab-separated columns
that represent the following information about each test:
• User
• Label
• Sensor Batch
• Sample Temperature
• Test Parameter
• Dilution Factor
• Unit of Measure
• Chemical Species
• Result
• Reference
Kemio is supplied with check standards (KEMC10) to
confirm the instrument is working correctly.
Kemio sensors produce an electric signal when used with
Kemio. Kemio measures that electric signal and displays the
corresponding concentration. The check standards produce
standard electric currents. If Kemio is able to measure
the expected signals from the check standards, then it
is performing correctly. Kemio will display "Pass" and the
complete test records will be stored in the data log.
If the measured signal does not match the expected values,
Kemio will display "Fail." Clean the check standard and Kemio
electrical contacts with a cloth or alcohol wipe, ensure the
check standard was properly inserted and repeat the test. If
the problem persists, contact your Palinteest representative
at [email protected].

Care and Maintenance
35 36
Kemio
Kemio is IP67 rated, however the electrical contacts inside the
front lid must be dry during testing. Open the front lid of the
arm and wipe the contacts with a dry lint-free cloth to remove
any moisture before inserting a sensor.
The touch interface is functional with droplets on the screen but
responds best when dry.
To maximize battery life, use deep charge cycles: use the
battery until it is very low before charging to 100%.
Kemio is an analytical instrument. Although it was designed to
perform in difficult application evironments, it is still a precise
measurement instrument. Do not handle roughly. Do not drop
the instrument or strike it with an object.
Kemio should be kept clean to ensure it is free from bacteria
and there are no interferences from contamination when
conducting measurements. Best practice is to use a dry and
absorbent cloth to remove any excess fluids or spillages from
the instrument as they occur.
Alcohol wipes can be used to clean the instrument if required.
Store Kemio in a cool, dry location.
Sample Vessel
Rinse sample vessel before use with sample, and rinse after
use with deionized water to prevent cross contamination.
Remove and empty the sample vessel after testing. Do not
leave sample water or sensors in the instrument as bacteria
could form.
Sensors
Do not handle or store sensors roughly in their packaging. Do
not touch the surface of the electrodes where the chemicals
are dosed, as this will affect the measurement result.
Sensors are single use. They can be disposed of with normal
waste.
If keeping sensors for over 1 year, store them in a refrigerator
to ensure they reach their expiration date.
Check Standards
Keep check standards clean and dry.
Check standards should not be used after their stated expiry
date. Replacement sets of KEMC10 are available for purchase.
