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.
Temperature data from thermocouple inputs is returned in the selected temperature units, with a resolution of 0.1 Deg C and an accuracy of better than 0.5 Deg C. The accuracy of temperature measurement with thermocouples is a function of the accuracy of the thermocouple, and not of the dataTaker. Thermocouples are available in a wide range of grades, varying from Â±0.1 Deg C accuracy to Â±5 Deg C accuracy.
