Introduction
The millisKanner multiplexer can be connected to your milliK Precision Thermometer to
increase the number of input channels for any 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 you with up to 33 measurement channels. The
millisKanner includes features that enable you to make the most accurate measurements
possible with your milliK. When you connect the multiplexer to your milliK, the additional
channels appear automatically on your milliK and can be configured and used in exactly
the same way as the milliK’s own input channels, so you can get on with making
measurements rather than worrying about how to control your 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 you complete freedom when configuring your
system. Channel selection would normally be controlled by 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 technology to implement channel
switching rather than the mechanical relays that are commonly used in multiplexers. This
completely solid-state design makes the millisKanner highly 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
