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.

1.1 Unpacking
UnpackingUnpacking
Unpacking
Your millisKanner product should comprise the following items:
millisKanner multiplexer
a universal power suppl with interchangeable plug heads
RS232 null modem cable
analogue link cable
this user manual
If ou have ordered a millisKanner to add to an existing millisKanner s stem, the power
suppl is replaced b a power lead and the analogue link cable is replaced b a
millisKanner-to-millisKanner link cable.
If an item is missing or damaged, please report this immediatel to our supplier. If
possible, we recommend that ou retain the packaging material in case ou need to
return the instrument for calibration or service since it has been designed to ensure that
our millisKanner is properl protected during transportation.

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.
Please observe the following safet precautions:
Do not use our millisKanner if it is damaged
Connect onl to a power suppl with a voltage corresponding to that on the power
suppl label (also given in the specification – see Section 9)
This equipment is for indoor use and will meet its performance figures within an
ambient temperature range of 5°C to 40°C with maximum relative humidit of 80%

©Isothermal Technolog Page 7 of 61 914 millisKanner manual Iss. 1.00
for temperatures up to 31ºC decreasing linearl to 50% RH at 40ºC
Equipment is for operation at installation categor II (transient voltages) and
pollution degree II in accordance with IEC 664 at altitudes up to 2000 metres
Alwa s use the power suppl supplied
This equipment is for use in moderate climates onl . NEVER use the equipment in
damp or wet conditions
Avoid excessive heat, humidit , dust & vibration
Do not place liquid filled containers on the equipment
Do not use where the equipment (or an associated accessories) ma be subjected

allow the unit to be switched off
Ensure that tabletop equipment is placed on a solid, level surface, which is able to
support its weight (and that of an attached accessories)
Ensure all cables and wires are routed safel to avoid tripping: also to avoid sharp
bends and pinches
Clean onl with a damp cloth. Do not wet or allow moisture to penetrate the unit.
Do not use solvents. See section 4.1 for details of cleaning procedure
The product should be subjected to regular in-service inspections as required b
local regulations; a earl interval is suggested
Do not appl earth test currents to an terminal/connector or to the shrouds of the

On the rear panel ou will find the 5 output connectors (4mm sockets), two RS232 ports
and two DC power inlets (for 5V DC). Two RS232 and power inlets are provided in order
to allow millisKanners to be “dais -chained” together. The unused RS232 port on the last
millisKanner in our s stem can be connected to a PC in order to control the whole
measurement s stem using our own software (see section 8). The command protocol
emplo s the widel used SCPI format (see section 8.2 for details).:

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.
