Geekcreit® AC 60-500V 0-100A D18 Square LED Digital Dual Display Voltmeter Ammeter Voltage Gauge Current Meter

Hi! Could you tell me how it works?Thanks!

What's if current flow in reverse, is there a minus sign?

Did that amimeter get to measure current in DC as well??

NONN is a GOOD PRODUCT, why don't you measure the currents under an ampere?It's not a nice thing, a person dies at 30 thousandths of ampere and he doesn't measure it?It made me very angry, but after the fifth purchased and tried I realized that it was not broken, is himself a great rip-off right?

do you have a wiring diagram for meter?Thanks!

Some meters bought show half the value, some show correct value, again others show double the value for amps. How to fix this?

How is this device powered? Is a separate DC voltage source required, and if YES, what voltage?

buongiorno ,dalle immagini si vede un oggetto che simultaneamente legge i volt e gli amper nello stesso quadrante ,poi in fase di ordine vedo un quadrante che mi legge o i volt o gli amper.non capisco cosa volete vendere visto che dalle spiegazioni non si capisce a che oggetto vi riferite ,a me servirebbe uno stumentino simile ma che legge contemporaneamente i volt e gli amper,questo oggetto cosa legge?

Does it work with the three-phase?

what are the two screws at the back of the unit? They look like some kind of wire hook up???

Can't I get a manual on how to plug them into the cornecct so that some light comes out of them.

Reading in the technical description I can't find the wording of how the display is powered, does it need fuse protection? if yes from what amp?

What is the output currency of the CT at 100A? Is ist a norm Value (100/1A or 100/5A)

preciso saber o valor deste equipamento em reais

Is it continuous rated like on through day and night

how can I connect to know current ampier....?

what is the power supply? are there batteries?

Hello.Do you have a gauge that can measure 200-500v and 200-250amp?

non capisco come si deve collegare

accuracy ?
