Draper 230V AC/DC Clamp Meter (51063)
Best OverallPros
- Measures both AC and DC current
- CAT III safety rating for professional use
- Clear backlit display for dim conditions
Cons
- Not True RMS (can be less accurate on non-sine waves)
- Build quality feels basic compared to premium brands
The Draper 51063 is the standard choice for electricians who need to measure both AC and DC current. Owner reviews on retail sites highlight its accuracy within +/- 2% for typical residential and commercial circuits. The CAT III 600V rating means it is safe for use on distribution boards and fixed installations.
Some users note the lack of True RMS as a limitation when working with variable frequency drives or LED lighting. However, for general fault-finding and routine checks, the 51063 delivers reliable results. The included test leads and carrying case add value for the price.
Draper 230V AC Clamp Meter (51062)
Best Budget ACPros
- Very affordable for basic AC measurements
- Simple one-handed operation
- Includes resistance and continuity functions
Cons
- No DC current measurement
- No backlight on the display
The Draper 51062 is the entry-level clamp meter for DIYers who only need to measure AC current on household circuits. Owner feedback praises its simplicity and low price. It is ideal for checking if a circuit is live or measuring the draw of appliances like heaters and air conditioners.
The lack of a backlight is a common complaint in dimly lit fuse boxes. Additionally, the absence of DC measurement limits its use for automotive or solar panel work. For its intended purpose, it offers good value.
Draper True RMS Clamp Meter (51064)
Best for AccuracyPros
- True RMS for accurate non-sine wave readings
- Measures AC and DC current
- Includes capacitance and frequency testing
Cons
- Higher price than standard models
- Jaw opening is only 30mm
The Draper 51064 is the upgrade for professionals who work with variable frequency drives, electronic ballasts, or other non-linear loads. Owner reviews consistently mention improved accuracy on distorted waveforms compared to the standard 51063. The added capacitance and frequency functions are useful for motor and component testing.
The 30mm jaw opening is sufficient for most single cables but may struggle with larger busbars. Some users wish for a larger jaw for industrial work. Overall, it is a reliable meter for commercial electricians.
Draper 1000A AC/DC Clamp Meter (51065)
Best for High CurrentPros
- 1000A range for heavy industrial circuits
- CAT III 1000V safety rating
- True RMS and data hold functions
Cons
- Bulky design for tight spaces
- Higher price point
The Draper 51065 is designed for industrial electricians who need to measure high currents on main distribution boards and large motors. The 1000A range covers most commercial and industrial applications. Owner reviews highlight its robust build and the high CAT III safety rating, which provides confidence when working near high-energy systems.
The larger jaw (40mm) accommodates thicker cables, but the meter itself is noticeably heavier and bulkier than lower-range models. For users who only work on residential circuits, the 600A models are more practical. The 51065 is a specialist tool for high-current environments.
Who is a Draper Clamp Meter For?
Draper clamp meters are aimed at both DIY enthusiasts and professional electricians who need a reliable, affordable tool for non-invasive current measurement. The range covers basic AC-only models for household checks up to True RMS and high-current versions for commercial and industrial work. They are a popular choice for electricians, maintenance engineers, and serious home renovators.
Performance and Build Quality
Based on aggregated owner reviews from major retailers, Draper clamp meters generally receive positive feedback for accuracy within their specified class. The standard models (51062, 51063) are noted for being straightforward to use with clear displays. The True RMS model (51064) earns higher marks for precision on non-sinusoidal waveforms.
Build quality is described as adequate for the price point. The plastic housing feels durable enough for regular use but not as rugged as premium brands like Fluke or Klein. The included test leads are functional but some users upgrade to silicone leads for better flexibility. The backlight on most models is a welcome feature, though the basic 51062 lacks it.
Alternatives to Consider
For users who need a more rugged meter, the Fluke 323 is a premium alternative with a higher build quality and a longer warranty. For those on a tighter budget, the Tacklife CM02 offers similar features to the Draper 51063 at a lower price, though with a lower safety rating (CAT II 600V). Professionals working exclusively on industrial systems may prefer the Klein CL800, which offers True RMS and a CAT IV safety rating.
What to Check Before Buying a Clamp Meter
First, confirm the current type you need to measure. AC-only meters are cheaper but useless for DC circuits like solar panels or automotive systems. Second, check the safety rating. CAT III is the minimum for commercial electrical panels. Third, decide if you need True RMS for accurate readings on modern electronics. Finally, consider the jaw size to ensure it fits around your typical cables.
Mistakes to Avoid
A common mistake is buying an AC-only meter for automotive work, which requires DC measurement. Another is ignoring the safety rating. Using a CAT II meter on a main distribution board is dangerous. Also, avoid assuming all clamp meters are True RMS. If you work with VFDs or LED drivers, a True RMS meter is essential for accurate readings.
