When the Humidity Probe was in stalled: Win Wiz found new hardware. They selected Yes & it auto found a Driver on the CD. We have been using Picoscope 6404D for quite some time, and are amazed by its accuracy and powerful emulations while working with numerous signal evaluations.

PicoLog 6 alarms can also trigger a digital output on devices with supporting hardware, such as the PicoLog 1000 Series, ADC-24 and DrDAQ. You can even trigger a digital output from one of these devices based on an alarm condition from another connected logger without digital outputs, such as a TC-08.Nothing in the help talks about Hardware drivers and nothing makes a connection even though it has the DLL and knows what and where it is.

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. 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 support Raspberry Pi computers.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'. 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. 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. 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.

The TC-08’s USB connectivity allows up to 20 TC-08 USB data acquisition modules to be used simultaneously on one PC making the TC-08 ideal for use as a large multi-channel temperature acquisition system with a cost per channel significantly lower than other systems of this size. The low conversion time of the TC-08 means up to 10 temperature measurements can be taken every second, while the high (20 bit) resolution ensures that the TC-08 can detect minute changes in temperature. With the TC-08 thermocouple data acquisition module your measurements can be made both fast and accurately. Simply plug the TC-08 into a USB port on your computer, connect your thermocouples, and you are ready to measure temperatures. 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 Does not matter how I search for the drivers. Win Wiz said it won't work properly and PICOLog cannot select it. 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. If users wish to install the last release of PicoScope 6 Beta for Mac (6.14.62), you can do so here. Release notes Picoscope 7.1.17 Early Access

The TC-08 can be used with thermocouple types J, K, T, E, R, S, B and N and outputs can be viewed in degrees F, C or mV. The unit is accurate to 0.2 percent ± 0.5 degrees C and has a resolution of better than 0.1 degrees C for most thermocouple types. 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).

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. 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! 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. In considering your measurement goals it's worth bearing in mind that, high temperature accuracy (how close the converted temperature value being logged is to the true temperature being measured) is more difficult to achieve when compared to other types of measurement (the ITS-90 standard, upon which all current temperature measurements are based, is only accurate to 5 decimal places, and unlike some other standards, e.g. derived at atomic level, using unique methods, ITS-90 was derived using more precise variants, of generally used apparatus and methods, e.g. a gold standard PT100 sensor, the triple point of water, and other known preset points). However, high temperature precision (the smallest measurable difference between 2 temperature values) is easier to achieve, with your average Data Acquisition Device typically having a resolution (which is essentially the digital equivalent of precision) of at least 10 times it's accuracy. The resolution of the TC-08 is approximately 100 times it's accuracy. As you are interested in how the NTC sensor changes relative to a fixed resistance value, I would say that what you need is a measurement system capable of high precision, rather than high accuracy. However, for completeness, we will discuss both precision and accuracy. 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.To explain why, you need to know about measurement goals, terminology, limits of measurement system capabilities, and more, so the complete answer (if you're interested) is as follows: However, the accuracy of the high precision, high accuracy thermistor you select (which, for example, can be something like ±0.2°C at 42°C) is going to be better than the accuracy of the TC-08 data logger (±0.584 °C at 42°C). The accuracy of the TC-08 is specified with an uncertainty (±) that is based upon factors such as the variation of component tolerances between individual units, and the variation of results between different data capture sessions. You can reduce the uncertainties due to tolerances by performing a calibration for accuracy (which performs measurements of temperature using one channel and one specific sensor to characterize the accuracy of the specific pair over a temperature range). This gives a much tighter uncertainty for the specific TC-08 model and specific channel + sensor, but only as long as they are always used together. The calibration house may then also be able to specify corrections required to reduce even further the extremes of temperature variation over the range. This can be done by making use of the extra resolution available to the data logger to make the corrections with a scaling file. At Pico Technology, we can do the calibration for accuracy for thermocouples, but you would need to approach an independent Calibration House if you want it done for a TC-08 + high precision, high accuracy thermistor.
