About this deal

We were a bit hesitant at first … but it worked flawlessly, and everybody is now out shopping for PicoScopes! and better still, utilising the Power over Ethernet (PoE) capability on the Raspberry Pi 3B+ paired 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 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 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'. 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. 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.

PicoScope 7 T&M – Early Access

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: When the Humidity Probe was in stalled: Win Wiz found new hardware. They selected Yes & it auto found a Driver on the CD.

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. 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 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. 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. 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.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 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.
