Training to use DSN-VC288 Digit Voltmeter Ammeter?

Thanks

When i connect shunt ampre readind going to zero, why?

Quick question. What happens if i try to read 105volts with it.... i have a power supply that can deliver little more over 100 and i dont want to burn the module. Will it burn if i exceed the 100v? or it wont show anything more than that 100 stucked in there.

I just bought two of those meters, I connected them the same as you, but, although it shows the use of voltage and the circuit works without problems, the meter does not measure the current, it is simply at 0, both meters behave the same.

thnks

سلام خسته نباشید ممنون مهندس یک توضیح کامل میخواستم دررابطه باطریقه فعال کردن آمپر من یک رسیورمینی دارم که دوازده ولت دوآمپره که ازطریق ماژول افزاینده وپاوربانک میخوام به رسیور برق برسونم اندازه گیری ولتاژوروکه بلدم ولی چطور آمپرو وصل کنم یاانتقال بدم به رسیور ومطمئن باشم که دوآمپر برق مصرف میکنه منظورم اینه دوسیم روبکجای رسیور وصل کنم ممنونم اگه یکم راهنمایی بکنید متشکرم موفق وپیروز باشید❤❤❤

The reality is that the old (analog) instruments could be used as long as no overcurrent was introduced by mistake, so they were good for many, many years.
Today's (digital) instruments don't last more than a year or two, and they break down if they happen to be near the high voltage of an old TV. Some of them are already defective, so today's technology is not user friendly, but hazardous waste friendly.

What is cost of this meter

20 HP 3 phase motor ke liye chahie

thank you so much
