Great functionality in a compact size. I really like moving the mouse pointer to a position and having the Time and Voltage display the values at that point. Calibration equipment is a breeze with that feature. When the Humidity Probe was in stalled: Win Wiz found new hardware. They selected Yes & it auto found a Driver on the CD. Alternatively, the resolution of the TC-08 is considerably better than the accuracy of a high precision, high accuracy thermistor. So, if you are in fact just looking for high precision changes then you already have that capability in your TC-08, and probably don't need to concern yourself with accuracy, calibration, and multiple capture sessions. First of all, the answer on a postcard is - if you are trying to do what I think you are, then it can be done with a better NTC thermistor alongside your 10K NTC thermistor, and the TC-08. The Early Access version can also be installed alongside the stable version on Windows and Mac, and will receive independant update notifications for all of the new features added with each release.
The TC-08 connects to the USB port of a Windows based PC and enables the host PC to automatically detect the TC-08 avoiding the need for any complex setup procedures. The USB connection also allows the TC-08 to be powered directly by the USB bus eliminating the need for an external power supply and making the TC-08 ideal for measuring temperatures both in the lab and in the field. A general rule of thumb in data acquisition is that, if you want to perform a calibration/measurement of a measurement system you should use a calibration/measurement system that is at least 3 times as accurate as the system you are measuring. A 10K NTC therimistor (which has a typical accuracy* of ±0.1°C at 20°C) is considerably more accurate and stable than a thermocouple (which has a typical accuracy* of ±2.7°C at 20°C) for measuring the same temperature range. So, a thermocouple would be beyond it's limit of accuracy* in trying to log thermistor temperature against its resistance. Perfect Partner for Development of Encoder controlled Stepper Motor Actuators. Since the included software is really stable, this type of device is a great tool for great tasks! So, although the thermistor is far too inaccurate and unstable, the TC-08 is a data logger (specialised for working with thermocouples, because of it's CJC, input range, etc, but still a data logger) with differential inputs, reasonable accuracy, and over 16-bits of resolutio, so it is capable of measuring voltage, resistance and current, to reasonable precision. You can measure the resistance of the 10K NTC thermocouple by using a constant current source to generate a voltage across the thermistor. The voltage should be matched at the maximum of your measurement range with the full-scale input for the input range you would be using on the TC-08 Terminal board (so you may need to divide down the voltage using a resistor divider). Alternatively you could use the 4-20mA input range on the Terminal board, and a voltage source, set to a voltage that provides 20mA through the thermistor at the maximum temperature of your measurement range. You can now connect the logger to the Pi and remove the keyboard, mouse and video to make an inexpensive stand-alone logger storing its captured data locally on a Pi SD card
You can reduce the systematic uncertainties due to measurement session variation by repeatedly taking the same measurements. By doing all this, the difference in accuracy between the TC-08 and a high precision, high accuracy thermistor should be easy enough to overcome. Note that when discussing how close the measurement is to the True value (qualitative assessment) we use the term 'Accuracy', but when referring to actual numerical values (quantitative assessment) we are actually defining how far away the measurement is to the True value, so the correct term is 'Accuracy Error', which over time has been (confusingly) abbreviated to 'Accuracy'.
It is also possible to set an alarm when a device becomes disconnected:an alarm is turned on, the event recorded and the graph annotated to show that the lost data was due to device disconnection. Does not matter how I search for the drivers. Win Wiz said it won't work properly and PICOLog cannot select it.

You can now connect the logger to the Pi and remove the keyboard, mouse and video to make an inexpensive stand-alone logger storing its captured data locally on a Pi SD-CARD Furthermore, connecting your Pi by WiFi or Ethernet, you can internet-enable your Pico logger which you can then access remotely using an open-source VNC server and viewer freely available Pico Log cannot select the TC-08 and refresh does not help. It sees the Humidity Probe straight away and just loads it without request. It is a great scope. I had a weird problem - it did not work on one of my PC’s. Customer service gave me first class service. If I could give 6 stars for customer service - I would do so.
and better still, utilising the Power over Ethernet (PoE) capability on the Raspberry Pi 4Bpaired with the PoE PiHAT not only eliminates the need for an external power supply and powered USB hub, it also internet-enables your logger at the same time Not many USB scopes works on Win & Mac & Linux too, so that proves me that guys from Pico really cares about us, customers. This made my decision much easier when I was looking to buy an USB scope. Pico Technology data loggers work great when USB connected to PCs running Windows, macOS and Linux, and now with support for Raspbian OS on armhfprocessors, we now support Raspberry Pi computers.

Release notes Picoscope 7.1.17 Early Access The TC-08 thermocouple data acquisition module is designed to measure a wide range of temperatures using any thermocouple that terminates in a miniature size thermocouple connector. Additionally the TC-08 can also measure other sensors using a ±70 mV range. Featuring built-in cold junction compensation (CJC), the TC-08 has an effective measuring range of -270 to 1820°C (the actual temperature range depends on the thermocouple type being used).
