有疑問？ 與我們聊天

客戶問題與解答

  • 題: What is the capacity range of this Battery Monitor?

    回答: The capacity range is 0-999Ah.
  • 題: Does the current sensor need to be placed on a specific side of the power?

    回答: No, the current sensor can be placed on the positive or negative side of power.
  • 題: What is included with this Battery Monitor?

    回答: It comes with a through-hole current transformer and one 2 meter long cable.
  • 題: How long are the wires and cables?

    回答: The sensor comes with a 2-meter long cable, but the factory can customize longer cables.
  • 題: Do the black and red leads connect to 12 volts source voltage for automotive car install?

    回答: There are two ways to wire: 1) from a power source, or 2) from the induced power from a hall transformer. Please refer to the website for the schematic.
  • 題: Does this version have the ability to reset Ah and kWh?

    回答: No, this battery tester/gauge is just a display device. It automatically resets when you remove the monitored voltage/current and turns off. When you reapply the voltage/current, it will show the new data.
  • 題: Will I need two of these if I'm using a battery isolator for two batteries in my audio system?

    回答: Yes, if you want to read each battery independently, you would need two.
  • 題: For this to work as a 'fuel gauge', do all charging and discharging cables need to go through the Hall Sensor?

    回答: Yes, that is correct.
  • 題: Why is my monitor reading FFF when using the inverter with high watt items?

    回答: Please check the parameters you established when setting it up.
  • 題: How big is the Hall effect sensor hole? What size wire/lug can pass through?

    回答: The hole is approximately 3/4 of an inch.
  • 題: Is this waterproof?

    回答: No, it is not waterproof.
  • 題: I lost my instruction manual for this unit. Where can I download a new instruction manual?

    回答: Please check the website again. You should be able to find and download the instruction manual there.
  • 題: Do you have a model to attach to a shunt of 1000A / 75mV?

    回答: No, my model doesn't use a shunt. It uses a Hall effect sensor transformer ring, similar to a CT transformer in AC power.

“Ubuy Hong Kong is a game-changer. I was looking for a specific American brand that doesn't ship to Asia, and Ubuy had it in stock. The selection of global products is incredible. It saves me the hassle of using freight forwarders or asking friends to bring items over. The process was seamless from checkout to delivery”
