Budget Multimeter Recommendations
A multimeter is the single most important tool on any electronics bench. It measures voltage, current, resistance, and continuity — the fundamental parameters of electronic circuits. Fortunately, capable multimeters are available at every price point.
Multimeter Comparison by Price Tier
| Model | Price Range | Key Features | Accuracy | Safety Rating | Best For |
|---|---|---|---|---|---|
| DT830B | $5-10 | Basic V/A/Ω, no continuity beep | ±1% | None (CAT I only) | Absolute beginners |
| AN8008 | $15-25 | 6000 count, auto-ranging, temp | ±0.5% | CAT II 300V | Hobbyists, students |
| AN870B | $25-40 | 9999 count, dual display, NCV | ±0.5% | CAT II 600V | Advanced hobbyists |
| Fluke 17B+ | $100-130 | 6000 count, rugged, reliable | ±0.5% | CAT III 300V | Entry professional |
| Brymen BM257s | $140-180 | 6000 count, true RMS, low-Z | ±0.3% | CAT IV 300V/CAT III 600V | Professional |
| Fluke 87V | $350-400 | True RMS, peak capture, robust | ±0.05% | CAT IV 600V | Industrial, field service |
What to Look For in a Budget Multimeter
Auto-ranging vs manual ranging: Auto-ranging multimeters automatically select the appropriate measurement range, saving time and reducing errors. For sub-$30 multimeters, auto-ranging is a must-have feature. The AN8008 and AN870B from Aneng offer excellent auto-ranging performance at budget prices.
True RMS: True RMS measurement accurately measures non-sinusoidal waveforms (PWM, square waves, modulated signals). If you work with switching circuits, motor drives, or digital signals, true RMS is essential. The Brymen BM257s is the cheapest multimeter we recommend that includes true RMS.
Continuity tester with beep: The ability to quickly check continuity with an audible beep is non-negotiable. Avoid any multimeter without this feature, including the ultra-cheap DT830B.
Input protection: Look for multimeters with fused current inputs and proper CAT ratings. Cheap multimeters without fuses can be dangerous when measuring current incorrectly. The fuse protects both the meter and the circuit under test.
Resolution and count: A 6000-count meter can display values up to 5999, providing better resolution than a 2000-count meter. For most electronics work, 6000 counts is sufficient. High-end meters offer 50000+ counts for precision measurements.
Recommended Starting Point
For engineers on a tight budget, the Aneng AN8008 at $15-25 is the best value. It offers auto-ranging, 6000-count resolution, temperature measurement, and reasonable accuracy. Pair it with a Brymen BM257s as your "serious" meter for critical measurements, and you have a capable two-meter setup for under $200.
USB Oscilloscopes: Hantek, PicoScope, and Alternatives
An oscilloscope visualizes electrical signals over time, making it indispensable for debugging digital protocols, analyzing analog circuits, and verifying signal integrity. Traditional bench oscilloscopes start at $400+, but USB oscilloscopes offer capable alternatives at lower prices.

|---|---|---|---|---|---|
| Arduino + R-2R DAC | Square, sine, arbitrary | 0-100 kHz | High | $5-10 | Programming |
| AD9833 module | Sine, triangle, square | 0-12.5 MHz | 200 Ω | $3-8 | SPI |
| AD9850 module | Sine, square | 0-40 MHz | 200 Ω | $8-15 | Parallel/SPI |
| JDS6600 | Sine, square, triangle, ramp | 0-60 MHz | 50 Ω | $80-120 | Front panel |
| Siglent SDG1032X | All standard + arbitrary | 0-30 MHz | 50 Ω | $280-350 | Front panel/USB |
AD9833: The $5 Signal Generator
The AD9833 is a programmable waveform generator IC available as a breakout module for $3-8. It generates sine, triangle, and square waves up to 12.5 MHz, controlled via SPI from any microcontroller.
Arduino AD9833 example:
#include <AD9833.h>
#define FSYNC_PIN 10
#define DATA_PIN 11
#define CLK_PIN 13
AD9833 gen(FSYNC_PIN);
void setup() {
gen.Begin();
gen.EnableOutput(true);
gen.ApplySignal(SINE_WAVE, REG0, 10000); // 10 kHz sine
}
void loop() {
// Sweep frequency from 1 kHz to 100 kHz
for (long freq = 1000; freq <= 100000; freq += 1000) {
gen.SetFrequency(REG0, freq);
delay(100);
}
}
