2024-02-03 03:50:04 Nuttig (0)Q: Hi, How many 1*****.7V cells are inside and what is their (real) specification ?
gevraagd door erosffoeg op 2023-06-19 03:48:20Q: What is the temperature measurement refresh rate to control the output ON/OFF ?
gevraagd door erosffoeg op 2022-05-11 04:33:58
jirze Refresh time is 20 msec to ON, 30 msec to OFF. Approximately.
2022-07-03 01:54:56 Nuttig (0)Q: Can I use this to measure temperature in my water heater (geyser)?
gevraagd door BG101517378 op 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.

The seller Sorry, no refresh rate tested.

erosffoeg Hi, Sorry I do not have it yet - will try to answer when delivered.
2022-05-04 05:41:05 Nuttig (0)Q: Can the 0V battery and 0V from panels be connected together ?
gevraagd door erosffoeg op 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
2021-06-03 10:22:07 Nuttig (2)Q: Are the input and output "GND"s directly connected ?
gevraagd door erosffoeg op 2022-04-26 03:19:38
The seller Yeah，that is right
2022-04-26 08:32:29 Nuttig (0)Q: If button is held pushed does it ring continuously - else how long does it ring ? Thanks
gevraagd door erosffoeg op 2020-02-15 04:27:37
aqol no just once it rings

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 Nuttig (0)Q: any way to calibrate with external resistor?
gevraagd door Camwads op 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.
