## Overview

The bayite Volt Amp Meter is a compact, waterproof digital gauge designed for real-time monitoring of DC voltage (5-100V) and current (±100A). Featuring a dual display and a Hall effect sensor with a 3/4 inch through-hole, it supports large wire diameters and allows multiple wire loops to amplify signals. Its electrical isolation ensures safety for sensitive equipment, making it ideal for automotive, solar, and battery management applications.

## Description

bayite DC 5-100V 100A Digital Volt Amp Meter is a 2-in-1 meter for real-time current and voltage monitoring. The display is large, easy to read, and accurate. Package even includes an extension cable (6.5 feet) for the Hall effect sensor, providing more versatile installaitons.

Review: J'ai installé 2 de ces lecteurs pour surveiller l'état des 2 batterie de mon vehicule, une pour la batterie principale et l'autre pour la batterie auxiliere. J'en suis entièrement satisfait.
Review: I've purchased several of these type meters. This one was different in a good way. First, IN THE BOX, it arrived with a single page, color diagram showing how to connect the meter, how to reset the meter and how to interpret the current (when neg flow). The text was in good sentences. The opening was large enough to pass over a 1/0 wire AND the lug. Out of the box, the current reading and voltage reading agreed with my calibrated meter. I'm using it on a 48V solar system to track inverter charge current and battery voltage (independent of the inverter) and its working great. No need for a separate 12V supply, it works directly off the range of voltage (45V to 58V).

## Features

- Dual display: Display Voltage and (+ -) Current at the same time; Power supply: DC 5~100V; Voltage test range: 0~300V; Current test range: ±0~100A
- Through-hole design: Easy Wiring; Measure positive or negative current; No current direction limitation
- Electrically isolated from high voltage power source which eliminates risk to delicate monitoring equipment and also minimizes safety concerns
- Compatible with large wire; Diameter of the sensor hole is 3/4 inch (19 mm)
- Loop through sensor multiple times to strengthen signal. For example, if your current signal is only 0.2 Amps, you could loop the wire through the sensor 10 times and the signal would by 10X stronger and would appear as 2.0 Amps

## Questions & Answers

**Q: Can the unit handle short period inrush current over 100A?
And why not allow remote reset button?**
A: Yes. It won't damage the meter with the short period current over 100A.

**Q: How long is the shorter CT cable? Only the length of the longer cable is listed.**
A: The length of the short CT cable is 5.9inch(15cm).

**Q: I see how you can zero the current measurement, but my voltage measurement is off by a full 0.5V. How is the voltage measurement calibrated?**
A: Please follow the instructions below to reset the voltage value to factory setting and it should solve the prolem.  If not, please click the link of "ask seller" in your order details to get a replacement.

How to reset the voltage value to factory setting:
Press and hold the back button for 6 seconds then release the button. And it will display "5HH" on the screen.

**Q: does this work with lead acid and lithium batteries ?**
A: You can measure any DC 5~100V 100A power source with this meter no matter what type of your battery.

I’m using it to monitor 12v battery, voltage is as my fluke meter +/- 50mV. My load is often around 0 to 7A, amp is as my fluke meter +/- 100mA
