Check battery voltage before the charge and after overnight charge. Your right about the 8 volt charger. You can use an automotive charger but will have to watch that it does not overcharge the battery. The 12 volts on 8 volt will charge it, but the best would be a 24 volt charger, where you could charge 3 at a time.
A high accuracy electronic cold junction compensation circuit maintains typical system accuracy of Â±0.2Â°C over an ambient temperature range of 15 to 35Â°C. Individual offsets may be added to each input in software to facilitate individual calibration of each channel. For information on our wide selection of Type T Thermocouple temperature probes.
Determine your accuracy and environment parameters. Calculate Absolute Accuracy for each system component. Use the Absolute Accuracy values to calculate the System Accuracy and System Accuracy Relative to Input (RTI).
