ZIBOO 17B Pro Multimeter Review: A Practical True RMS Tool for Home and Auto Testing

Introduction

For anyone who regularly tests and troubleshoots electrical systems, a reliable multimeter is one of the most useful tools to have on hand. The ZIBOO 17B Pro is a true RMS digital multimeter designed for vehicle and home electrical work, and it comes with a range of measurement functions that cover most everyday testing needs.

This review covers the multimeter itself as well as the optional ZIBOO i600E AC current clamp, which extends the tool’s capability to safely measure AC current draw on appliances and other loads. Both products are positioned as affordable options for practical testing work.

What the ZIBOO 17B Pro Offers

The 17B Pro is a true RMS digital multimeter, which means it can accurately measure AC voltage and current even when the waveform is not a perfect sine wave. This makes it suitable for testing modern electronics and vehicle systems where waveforms can be distorted.

The multimeter measures AC or DC voltage, AC or DC current, capacitance, diode forward voltage, continuity, and non-contact live voltage. It also includes temperature measurement through a thermistor probe that connects to the meter.

The package includes positive and negative test probes, batteries, a user manual, and the thermistor. An optional yellow rubber case is also available for those who prefer a different color over the standard red cover.

Design and Build Quality

The 17B Pro has a large 3-inch backlit LCD display that remains readable in dim conditions. The mode selector dial sits in the center of the front panel and rotates through the various measurement functions.

One notable design choice is the accessible fuse compartment. The two fuses are located behind the back panel, which means they can be serviced without fully disassembling the meter. Many multimeters hide the fuses behind an internal cover, requiring more effort to replace them when they blow.

The red rubber protective cover can be swapped for the yellow version by pulling back the existing cover and sliding on the replacement. This gives users a simple way to personalize the tool or make it easier to spot in a crowded toolbox.

Voltage, Resistance, and Diode Testing

The 17B Pro is an auto-ranging multimeter, so users do not need to manually select the voltage range before taking a measurement. It can measure from 0 to 1,500 V DC or 0 to 1,000 V AC. For those who prefer manual control, the range button allows the decimal point to be moved to select a specific range, and pressing and holding the button returns to auto mode.

In testing, the meter measured a tool battery at 16.3 V DC. The hold button locks the current reading on the display, which is useful when the probes are in a hard-to-reach location.

For AC voltage, the meter measured 118 V AC from a standard outlet. The frequency function can also be selected to read the line frequency, which measured 60 hertz in this test.

Resistance measurements were accurate on both a 220 ohm resistor and a 1 k ohm resistor. The continuity function works through the mode button, and the diode test measures forward voltage. A 1N5402 power diode measured 0.556 V forward voltage, and an LED illuminated during testing with a reading of 1.89 V.

Capacitance and Current Measurement

The capacitance function measured a 6,800 microfarad capacitor at 6.38 mF, which converts to 6,380 microfarad when the decimal point is moved three places. This is useful for checking capacitors in power supplies and other electronic equipment.

For current measurement, the meter can measure up to 10 amps. Testing a 12 V halogen bulb connected to a power supply showed a draw of 4.89 amps, which is consistent with typical halogen bulb consumption. The meter is connected in series with the load for direct current measurement.

Temperature Measurement and NCV Detection

The included thermistor connects to the meter through the probe ports, and the mode button toggles between Celsius and Fahrenheit readings. This allows users to check the operating temperature of transistors, chips, and other electronic components. In testing, heating the thermistor with a heat gun caused the temperature reading to rise accordingly.

The non-contact voltage (NCV) function uses a sensor at the top of the meter to detect live AC voltage without touching the conductor. Placing the top of the meter near an outlet produced a live voltage indication, which is a useful safety check before working on wiring.

Using the i600E Current Clamp

The ZIBOO i600E is an optional AC current clamp that connects to the multimeter through the probe ports. It can measure up to 600 amps of AC current. The clamp opening is 1.26 inches or 32 mm wide.

The clamp works by converting inductive AC current to millivolts. According to the label on the clamp, 1 mV equals 1 amp, up to 600 mV equals 600 amps AC. When the meter is set to the clamp symbol and AC current mode, the reading on the display represents the current draw directly.

To measure the current draw of a device, the clamp must be placed around a single conductor, not the entire power cord. A line separator or a modified extension cord with exposed wires is needed so the clamp can be positioned around either the hot or neutral wire.

In testing, a heat gun measured 5.4 amps on the live wire and 5.6 amps on the neutral wire. Increasing the heat setting raised the readings to 6.4 amps and 6.3 amps respectively. Switching the meter to AC millivolt mode showed 5.3 mV and 6.3 mV readings, which correspond to 5.3 amps and 6.3 amps AC, confirming the clamp’s conversion ratio.

Buying Advice

The ZIBOO 17B Pro is available for under $50, making it an affordable option for anyone who needs a reliable true RMS multimeter for regular testing and troubleshooting. The i600E current clamp retails for $24, which is a reasonable add-on for those who need to measure AC current draw on appliances or other loads.

For users who work on vehicles, home electrical systems, or electronics, the combination of auto-ranging, true RMS measurement, accessible fuses, and the optional current clamp makes this a practical kit. The temperature measurement and NCV detection add further versatility without complicating the basic operation.

Conclusion

The ZIBOO 17B Pro digital multimeter delivers solid build quality, a clear display, and a comprehensive set of measurement functions at an accessible price point. The auto-ranging feature simplifies operation, while the accessible fuse design and optional yellow cover show attention to practical details.

The i600E current clamp extends the meter’s usefulness for AC current measurements, making the pair a strong choice for both home and automotive electrical work. For anyone in the market for a dependable multimeter for troubleshooting and testing, the 17B Pro is worth serious consideration.
