السؤال بواسطة BG101517378 على 2022-05-12 12:45:42
erosffoeg The probes look to be water proof but I would not trust continuous immersion. Suggest you find a place that you can make probe external contact with the geyser tank skin directly.

السؤال بواسطة erosffoeg على 2021-06-02 10:38:44
kezbaroo Shortanswer is NO. The positives are all common and the negatives are all separate. If connected together the solar panel will be directly connected to the battery and will not regulate

erosffoeg Hi, Sorry I cannot help as mine has not arrived yet. However I intend to uses it as a CNC router and will make a clamp or fixing to fit it whatever size it is. Do not thaink it will be difficult as the body looks to be aluminium ( I hope !! ) therefore plenty of places to fit clamp etc. Maybe use the fixing points that were for the base plate ?

2021-06-04 10:45:21 مساعدة (0)سؤال: any way to calibrate with external resistor?
السؤال بواسطة Camwads على 2021-05-27 07:38:38
erosffoeg It uses an NTC resistor as the sensor like most other cheap meters. The NTC is very non-linear and so the NTC resistance is measured and then the non linearity is compensated for. Adding a series resistor will increase the displayed temp - and a parallel will decrease it. So yes you can calibrate that way - problem is though that the internal compensation will not now be correct and so high accuracy will only be a the calibrated temp. The error across a range of temps will be related to the amount of correction made at the calibration temp. NTC range is from several K down to low 100s.
