    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.

  • Page 6: Safety

    Safety Safety The millisKanner is a precision instrument, designed for use in a laboratory. It complies with the requirements of safety standard EN61010-1 (2010) and is therefore safe to use in laboratory or light industrial environments. It is not intended for use outdoors or in extreme environments (refer to specification in Section 9).

    You can still communicate with the milliK even though there is no physical connection to it as the millisKanner will relay commands from the PC to the milliK and will relay back responses from the milliK to the PC (see section 8 for further details).

  • Page 16 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 ‘daisy-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.
  • Page 17 If you do not use this feature, or are controlling the millisKanner manually (see section 2.5) you should use good quality, low thermal EMF connectors to connect between the millisKanner and the instrument.
  • Page 18 If a command is sent to the millisKanner to change channels, it returns a <CR> (carriage return) when the change has been made. Any software you 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.

  • Page 24: Connecting Thermocouples

    Connecting Thermocouples Connecting Thermocouples Connect thermocouples to your millisKanner by using miniature thermocouple plugs that plug into the sockets below the binding posts for that channel. Copper miniature thermocouple plugs should be used if you intend to use an ice point reference or external reference junction compensation.

    (ensure that it is isothermal with the reference junction). Connect this sensor to another channel (on the milliK or a millisKanner) and configure it with a conversion to temperature units. If you do not first configure the channel so that it can measure temperature, it cannot be used as the reference junction sensor.

  • Page 26: Connecting Thermocouples (Using Internal Compensation)

    To use a thermocouple with internal reference junction compensation (reference junction formed within the millisKanner and its temperature measured using an internal sensor), fit a thermocouple connector of the same type as the thermocouple and connect this to the socket below the binding posts.

  • Page 34: Calibration Calibration

    Before You Check the Calibration Any calibration should be performed in a temperature controlled environment between 19°C and 25°C. The millisKanner should be powered up and left to stabilise in the calibration environment for at least 2 hours before checking or adjusting calibration.
  • Page 35 This approach has the advantage that the difference between room temperature and the reference junction in the millisKanner is likely to be very small (< 3°C) so any error resulting from imperfections in the thermocouple will also be small.

  • Page 36: Adjusting The Reference Junction Sensor

    Reference Junction Sensor Reference Junction Sensor You can adjust the calibration of the millisKanner using the RJC Sensor Calibration feature in the milliK to which it is attached. Before you can use this feature you must first attach a calibrated thermocouple to one of the channels and configure the channel for use with this thermometer (see milliK manual for details).

    Command: [ROUTe:]CLOSe {POSitive|NEGative} Format: [ROUTe:]CLOSe<input#> Selects (connects input to output) the specified input (on the millisKanner to which the RS232 connection is made). The polarity of the sense terminals is defined by the {POSitive|NEGative} parameter. The millisKanner returns a <CR> (carriage return) to acknowledge that the channel has been selected and is ready to use.

  • Page 52: Command: Milliskanner:list

    This command is used by the milliK to ‘discover’ which millisKanners are connected in the ‘daisy-chain’. It reports information on the millisKanner and also forwards the command to the next millisKanner in the daisy chain (on the alternate RS232 port) so that it will also respond.

  • Page 53: Command: Milliskanner:start

    Format: MILLiskanner:STARt? Reports the channel number of the first input (on the millisKanner to which the RS232 connection is made). Example: in a system with two millisKanners connected to a milliK, the response to the MILLI:START? command sent to the second (last) millisKanner in the daisy-chain is “20”.
