IntroductionIntroduction
Introduction
The millisKanner multiplexer can be connected to our milliK Precision Thermometer to
increase the number of input channels for an combination of PRT, thermocouple or
thermistor sensors. Each multiplexer has 8 input channels and up to 4 millisKanners can
be connected to a single milliK, providing ou with up to 33 measurement channels. The
millisKanner includes features that enable ou to make the most accurate measurements
possible with our milliK. When ou connect the multiplexer to our milliK, the additional
channels appear automaticall on our milliK and can be configured and used in exactl
the same wa as the milliK’s own input channels, so ou can get on with making
measurements rather than worr ing about how to control our multiplexer.
Each channel is provided with 5 binding posts (for connection to a PRT or thermistor
sensor with bare-wire, 4mm plugs or spade connections) and a miniature thermocouple
connector. The output from the millisKanner is connected to Channel 2 of the milliK
(Channel 1 remains available). Each channel can be configured for use with PRTs,
thermocouples or thermistors giving ou complete freedom when configuring our
s stem. Channel selection would normall be controlled b the milliK (via the RS232
interface), but manual control is also supported with the left/right buttons on the touch
panel.
The millisKanner uses the latest semiconductor technolog to implement channel
switching rather than the mechanical rela s that are commonl used in multiplexers. This
completel solid-state design makes the millisKanner highl reliable. The sense input
reversal (used to eliminate the effect of thermal EMFs on thermocouple measurements)
and internal reference junction sensor used in the milliK are reproduced in the

©Isothermal Technolog Page 5 of 61 914 millisKanner manual Iss. 1.00
millisKanner. This means that measurements made using the millisKanner meet the same
uncertaint specification as those made with the milliK directl . The millisKanner does
not provide keep-warm currents, if this is required for a thermometer it should be
connected directl to the milliK.
This manual provides a comprehensive guide to using our millisKanner. We recognise
that ou will probabl not wish to read it through at this time so suggest ou read the
safet section below, turn to Section 2.2 (to learn how to connect the millisKanner to
our milliK) and then refer back to the manual using the list of contents to find additional
information as required.

1.2 Safet
SafetSafet
Safet
The millisKanner is a precision instrument, designed for use in a laborator . It complies
with the requirements of safet standard EN61010-1 (2010) and is therefore safe to use
in laborator or light industrial environments. It is not intended for use outdoors or in
extreme environments (refer to specification in Section 9).
The millisKanner is likel to be connected to thermometer sensors in use and the
operator should take care to ensure that the complete s stem is safe. For example, metal
sheathed thermometers ma be connected to the millisKanner and then placed in a
furnace powered from a 230V electrical suppl . Single fault conditions in such a furnace
could lead to the thermometer wires and therefore the binding posts and output
connectors of the millisKanner becoming electricall live and therefore a hazard to the
operator. Suitable precautions should be taken, such as using an isolating transformer in
the suppl to such a furnace. If ou require further advice on safet issues, please
contact Isothermal Technolog or one of our appointed distributors - we have extensive
experience of thermometr and can provide advice and equipment to help ou.
Retain these instructions. Use onl as specified in these operating instructions or the
intrinsic protection ma be impaired.

Using our millisKannerUsing our millisKanner
Using our millisKanner
Your millisKanner is ver eas to use, simpl connect it to our milliK Precision
Thermometer (analogue and RS232 connections) and appl power to both instruments.
On power-up, the milliK ‘discovers’ an millisKanners connected to it and assigns
channel numbers to each input. These additional channels then appear in the list of
channels and can be configured and used in the same was as the existing channels on
the milliK.
The automatic discover process takes place during initialisation of the milliK software
and requires the RS232 connection(s) to be present (see sections 2.2 or 2.3). If ou
connect or power the millisKanner after the milliK software has initialised (at the initial
screen with the Start button, or later), press the Restart/Update Software button on the
Instrument screen of the milliK to re-invoke the discover process.
A millisKanner will onl work with a milliK that is running with firmware version 1.11 or
above and software version 1.5.4 or above. The firmware and software versions are
shown on the milliK in the opening screen (with the Start button). If our milliK is running
with older firmware or software, please contact Isothermal Technolog or one of our
appointed distributors to arrange an upgrade. The hardware on all milliKs is compatible
with millisKanner multiplexers.

The power suppl operates from an standard AC electrical suppl (90-264V RMS at 47-
63Hz), so unless our suppl is unusual ou can simpl connect the power suppl to a
suitable electrical outlet.

©Isothermal Technolog Page 11 of 61 914 millisKanner manual Iss. 1.00
The power suppl is fitted with a standard BS 1363 plug head but is provided with
alternative heads that cover the majorit of electrical sockets used worldwide. If ou need
to connect to an outlet socket that is not supported b the plug heads provided ou
should source a suitable electrical suppl lead locall that is fitted with a C8 connector,
ou can then plug this directl into the C8 socket on the power suppl . The plug head
can easil be changed:
Plug the DC connector from the power suppl into either of the “DC Power” sockets on
the rear of the millisKanner.

If the software on the milliK is alread running, restart it b c cling the power or pressing
the Restart/Update Software button on the Instrument screen. This initiates the
automatic discover process so that the milliK can detect an millisKanners connected to
it and assign channel numbers. The milliK will disable Channel 2, since it is alwa s used
as the expansion channel input.
With a single millisKanner, the milliK assigns channel numbers 10 to 17 to the
multiplexer. The numbers (0 to 7) below each set of input terminals on the millisKanner
help to identif the terminals for each Channel (for example, the input marked as 4 is
Channel 14). The red LED (below the terminal posts) will light when measurements are
being made on that channel.
If ou want to control the measurement s stem (milliK and millisKanner) from a PC,
connect the unused RS232 port on the millisKanner to a PC using a null modem cable.
You can still communicate with the milliK even though there is no ph sical connection to
it as the millisKanner will rela commands from the PC to the milliK and will rela back
responses from the milliK to the PC (see section 8 for further details).

2.3 Connecting Multiple millisKanners to a milliK
Connecting Multiple millisKanners to a milliKConnecting Multiple millisKanners to a milliK
Connecting Multiple millisKanners to a milliK
You ma connect up to four millisKanners to a single milliK, giving a maximum of 33
input channels (channel 1 on the milliK and channels 10 to 17, 20 to 27, 30 to 37 and 40
to 47 via millisKanners). The first millisKanner in a s stem is supplied with an analogue

©Isothermal Technolog Page 15 of 61 914 millisKanner manual Iss. 1.00
link cable terminated with a Lemo connector and a universal power suppl . Additional
millisKanners are provided with analogue link cables terminated with stackable 4mm
plugs at both ends and a DC power link cable so that ou can create the required
expanded s stem.
First connect a single millisKanner to our milliK (see section 2.2 above). Use the null
modem cable provided (see section 8.1 if ou wish to make our own cable) to connect
the unused RS232 port on the rear of additional millisKanners to the unused RS232 port
on the previous millisKanner to form a ‘dais -chain’ arrangement. The RS232 ports on
the millisKanner are completel interchangeable, so it does not matter which is used to
connect to the next millisKanner or the milliK in the s stem. Similarl , use the Power Link
cable provided to connect either DC Power connector on the millisKanner to the unused
DC Power connector on the previous millisKanner in a ‘dais -chain’ arrangement.
Connect the five Output Terminals on the additional millisKanners (in parallel) to the first
millisKanner (the analogue cables provided use plugs that allow “pigg -back” connection
to make this eas ):
If ou wish to make our own analogue link cables, use a screened cable with low
dielectric loss insulation such as PTFE or pol eth lene (otherwise measurement
performance ma be affected). The screen should be connected to the ground terminals
on both millisKanners.

©Isothermal Technolog Page 16 of 61 914 millisKanner manual Iss. 1.00
If the software on the milliK is alread running, restart it b c cling the power or pressing
the Restart/Update Software button on the Instrument screen. This initiates the
automatic discover process so that the milliK can detect an millisKanners connected to
it and assign channel numbers. The milliK will disable Channel 2, since it is alwa s used
as the expansion channel input.
With multiple millisKanners, the milliK assigns channel numbers 10 to 17 to the
multiplexer connected directl to it. It then assigns channels numbers 20-27 to the next
multiplexer and so on. This means that the channel marked 7 on the third millisKanner in
the ‘dais -chain’ of RS232 connections will be assigned channel number 37. The red LED
(below the binding posts) will light when measurements are being made on that channel.
If ou want to control the measurement s stem (milliK and millisKanners) from a PC,
connect the unused RS232 port on the millisKanner at the end of the ‘dais -chain’ to a
PC using a null modem cable. You can still communicate with the milliK even though
there is no ph sical connection to it as the millisKanners will rela commands from the
PC to the milliK and will rela back responses from the milliK to the PC (see section 8 for
further details).

Although the millisKanner has been designed specificall to work with the milliK
Precision Thermometer, it can be used with an other compatible instrument. The onl
requirement for compatibilit is that the instrument must be able to accommodate the
series resistance of the millisKanner, which is 5Ω (maximum) in series with each line. The
switching devices are rated at 0.5A and 60V (across open contacts), so should be
compatible with most thermometr instruments. The millisKanner is designed to switch

©Isothermal Technolog Page 17 of 61 914 millisKanner manual Iss. 1.00
low-level signals, never use it to switch currents other than PRT/thermistor sense
currents or voltages above 60V.
The reference junction temperature is measured b a digital sensor and is onl available
via the RS232 interface. If ou wish to use internal reference junction compensation, ou
will need to access the reference junction temperature via the RS232 interface using the
MEAS:RJC? command (see section 8.2.6.16) or the MILL:RJC:TEMP#? command (see
section 8.2.6.14).
Make up our own (screened) cable to connect the five output terminals on the rear of
the millisKanner to our instrument. Select channels using the RS232 interface (see
section 8) or manuall (see section 2.5).
If ou are controlling the millisKanner using the RS232 interface and making voltage
measurements (for thermocouples), make two measurements with opposite polarit
(using CLOS# POS and CLOS# NEG commands) and calculate half the (signed) difference
between the measurements in order to eliminate the effect of thermal EMFs generated in
the connection between the millisKanner and the instrument. This uses the internal sense
reversal feature of the millisKanner to make the highest accurac voltage measurement.
If ou do not use this feature, or are controlling the millisKanner manuall (see section
2.5) ou should use good qualit , low thermal EMF connectors to connect between the
millisKanner and the instrument. The following Multi Contact 4mm stackable plugs are
recommended for the connection to the millisKanner:

their website www.farnell.com
If a command is sent to the millisKanner to change channels, it returns a <CR> (carriage
return) when the change has been made. An software ou write should take advantage
of this feature and wait for the change to be acknowledged before making a
measurement as this will ensure that erroneous measurements are not made during a
transition.

select Channel 0. Press the ‘Right’ button when Channel 7 is selected or the ‘Left’ button
when Channel 0 is selected to turn off all channels. The ‘Channel LEDs’ indicate which
channel is selected.
When the millisKanner is connected to a milliK, the left/right buttons no longer operate
because the milliK sends the REM (see section 8.2.6.1) command to disable local control
of the millisKanner. To re-enable the left/right buttons, either send the LOC command
(see section 8.2.6.2) to the RS232 port or c cle the power to the instrument.
The millisKanner can be used manuall with the milliK (do not connect it to the milliK
with the RS232 cable so that it is not detected b the milliK) or with another compatible
thermometer instrument. In both cases, the feature that reverses the sense connections

and connectors between the millisKanner and the instrument) does not operate. This
means that the voltage offset will be higher than when it is used with a milliK although it
should be well within the ±2µV specification of the milliK provided good qualit (low
thermal EMF) connectors are used.
