Digital Pen Multimeter YF-38C (YF-38C High Precision) AC/DC Voltage Tester, Resistance & Continuity
Product description
Key takeaways
A pen-style multimeter like the Digital Pen Multimeter YF-38C is one of those tools you don’t realise you need until a quick check saves time. It’s built for spot testing: AC/DC voltage checks, resistance readings, diode voltage drop, and continuity with a buzzer. On paper, it covers a lot of everyday electrical troubleshooting without you having to reach for a full bench meter.
What stands out is the convenience angle. With data hold, auto power off, and a backlight, you can still read values in dim conditions. There’s also a flashlight for working in awkward spots. The safety story also matters: double insulation, CE 600V CAT III, and audible feedback when the circuit is connected or disconnected.
That said, it’s not going to replace every higher-end meter workflow. If you’re doing deep diagnostics regularly, you may find a pen form factor less comfortable for extended measurements, and the specified accuracy (given as ±0.5%) suggests it sits more in practical testing than precision metrology.
It’s a sensible buy if you want a handheld, quick-to-grab tester for automotive and household checks—distribution boxes, fuses, and general circuit troubleshooting—where speed and readability matter.
The essentials
The YF-38C is a digital pen multimeter designed to measure AC/DC voltage as well as resistance and continuity. The base information provided mentions:
- Voltage measurement from 600mV up to 600V (AC/DC)
- Resistance range listed as 600 to 60M ohms
- Positive diode voltage drop
- Continuity testing with a sound (buzzer)
It also notes ergonomics: the pen shape is meant to be easier to handle than a traditional multi meter, which is especially helpful when you’re working in tight spaces or above head height. The unit also includes backlight for the display, data hold so you can pause the reading, and auto power off to avoid flattening the meter when it’s left on.
A practical example
Say a household plug or small appliance stops working and you suspect a break in the circuit. With this kind of tester, you can check continuity to see if the path is open or closed, and use the voltage range to confirm whether power is actually present where you expect it. The buzzer feedback makes continuity checks quicker than watching a changing number.
Where it shines
If your goal is fast, on-the-spot electrical checks, this pen multimeter makes a lot of sense. The main day-to-day advantages are:
- Readability when lighting isn’t great: backlight helps you see measurements, and the flashlight helps you work.
- Lower friction for quick tests: pen design is aimed at being comfortable to hold when you’re troubleshooting.
- Helpful test behaviours: data hold is useful when readings change or you need to record what you saw.
- Safety-focused feedback and protection: double insulation and CAT III rating (CE 600V) are included, plus a buzzer when the circuit connection state triggers.
Is it perfect? Not necessarily. Pen meters can be a bit less intuitive if you’re used to full-size multimeters, especially for tasks that require lots of stable contact time. And while the listed ranges are broad for a tester of this style, it may feel limiting if you’re expecting the depth of capability of more specialised measuring gear.

Is it worth it?
Buy the Digital Pen Multimeter YF-38C if you’re after a practical, handheld tester for common AC/DC voltage checks, resistance checks, and continuity testing—especially for household electrical troubleshooting and automotive-style diagnostics where you want something quick and easy to use.
You may want to skip it if you need a higher-spec measuring tool for precision work beyond what’s implied by the stated ±0.5% accuracy, or if you find pen meters awkward for long measurement sessions. Also, if safety labels and ratings are critical for your setup, it’s worth double-checking the exact guidance that applies to your intended work before relying on any tester.
FAQ
What’s it mainly for?
It’s positioned as a pen-type multimeter for troubleshooting: measuring AC/DC voltage, resistance, diode voltage drop, and continuity with a buzzer.
Can it be used in dim conditions?
Yes—there’s a backlight for the display and a flashlight for working in darker environments.
Does it have continuity testing?
Yes. The buzzer sounds when the circuit is disconnected or connected, which helps with quick continuity checks.
Is it safe to use for electrical checks?
The information provided highlights double insulation protection and CE 600V CAT III. That’s a positive sign, but it’s still worth following safe working practices for whatever task you’re doing.
Who is it best suited for?
It suits people who want an easy-to-grab tester for routine electrical troubleshooting rather than a dedicated instrument for specialised measurement tasks.
