jbb99 My guess is that you have a faulty module. I'd ask for a replacement.

jbb99 I can't help you compare LCD displays, but the battery in this multimeter seems to last well, I've been using mine a fair bit and it hasn[t needed changing. What does your second sentence mean?

jbb99 I very much doubt it. That's not what it is designed to do.

jbb99 It depends on whether you want your two cells to be in series or parallel. Very basic electronics:- parallel will give you around 3.7V, series will give you around 7.4v . If you want parallel, both cells are the same way round, and both leads will measure 3.7V. If you want series - insert the cells 'head to tail' i.e. follow the colour coding of the wires! I hope you haven't destroyed any circuits, blown up any batteries, or started a fire!!!
2020-09-25 05:05:14 Hilfreich (0)Q: What size DC power plug does it require, 2.1mm or 2.5mm? Thanks
gefragt von xjr13m auf 2020-09-06 10:51:23
jbb99 The plug I use measures 5.5mm od, and the inner hole 2mm, so 2.1 seems to be the answer. The inner pin is +. HTH John

jbb99 Hi Elmir, all general instructions on using a bms mention a P- connection. So I have the same question as you. Did you work out how to connect this particular BMS properly? And also did you find out what value of NTC to connect? Any help much appreciated! John
2020-09-05 07:27:54 Hilfreich (2)
jbb99 Thanks for confirming those connections. Have you added the 470microF 25V capacitor mentioned elsewhere? I'm intending to use this to convert a NiCad drill to Li-ion, and am wondering if the capacitor is necessary in my case. Any thoughts gratefully received. John
Q: what type of batteries does it use? (AA / PP3 / or what? )
gefragt von jbb99 auf 2019-06-15 07:10:31
Philiski the meter uses 1 1.5v LR14 type C battery and 1 9v battery. both fit very snug in the battery compartment.
