Hioki 3288 and 3288-20: Specifications and Features
1. AC/DC Current Measurement up to 1000 A
Both the 3288 and 3288-20 models are capable of measuring AC and DC current up to 1000 A. This makes them ideal for industrial installations, large electrical panels, and other high-current applications.
2. Additional Functions: Voltage, Resistance, and Continuity
These models also measure AC/DC voltage, resistance, and feature a continuity check with a built-in beeper—great for quickly identifying issues in electrical installations.
3. Average Rectified vs. True RMS
-
The Hioki 3288 uses the Average Rectified method, best suited for pure sine wave signals.
-
The Hioki 3288-20 features True RMS technology, which provides more accurate measurements for irregular waveforms, such as those from inverters or motors.
4. Double Jaw Lever Design
Equipped with dual levers, the clamp makes it easier to grip wires—even in crowded panels. The jaw opening is 35 mm, large enough for most power cables.
5. Battery Life and Accessories
These models are powered by AAA batteries, providing extended and reliable performance. Most packages include a carrying pouch and test leads.
Hioki 3283 and 3287: Specifications and Use Cases
1. Current Capacity and Accuracy
-
Hioki 3283: Measures AC current up to 1000 A but does not support DC current.
-
Hioki 3287: Supports both AC and DC measurements using True RMS, making it suitable for more complex electrical systems.
Both models offer high accuracy and come with a low-pass filter to reduce electrical noise interference during readings.
2. Core Functions and Special Features
-
The 3283 is focused on AC current and voltage measurements.
-
The 3287 has a wider measurement range and higher sensitivity, making it ideal for automation and advanced electrical tasks.
3. Best Applications
-
The 3283 is great for routine checks and standard electrical work.
-
The 3287 is better suited for industrial settings, solar power systems, and electric vehicles where precise DC measurement is needed.
How to Choose the Right Hioki Clamp HiTester
To make sure you get the right clamp meter for your work, consider these important factors:
1. Current Range and Measurement Type
Choose a model that matches your required current capacity. If you frequently measure DC or non-sinusoidal signals, go with a True RMS model like the 3288-20 or 3287.
2. Work Environment Compatibility
For confined spaces, select a compact model with an easy-to-use clamp. Also, consider models with appropriate safety ratings and IP protection if you'll be working outdoors or in harsh conditions.
3. Price and Warranty
True RMS models typically come at a higher price point but offer greater measurement accuracy. Hioki is also known for its reliable after-sales support and generous warranty coverage.
Tips for Using and Maintaining Your Hioki Clamp HiTester
To keep your clamp meter performing optimally for the long term, follow these maintenance tips:
1. Maximize Accuracy
-
Always zero out the display before measuring DC current.
-
Avoid performing measurements near strong magnetic or electric fields.
2. Battery and Storage Care
-
Use high-quality batteries and replace them regularly to avoid leakage.
-
Store the device in a dry environment at ambient temperature.
-
Use a protective case to avoid physical damage.
3. Common Troubleshooting Tips
If the screen doesn’t turn on or readings are unstable:
-
Check the battery and test lead connections.
-
Remove any dust or metal particles from the clamp jaws.
-
Reset the device if needed or contact Hioki service support.
