Note: The 3280-90F includes both the meter and an AC Flexible Current Sensor. 1: AC CLAMP METER 3280-20F×1 2: AC FLEXIBLE CURRENT SENSOR CT6280×1 3: CARRYING CASE C0205×1
Hioki clamp meters are best-in-class measuring devices incorporating Hioki’ s expertise in current sensing technology. The 3280-20F is a True RMS rectifying 1000A AC clamp meter that features a broad operating temperature range of -25° C to 65° C, thin and compact clamp core and optional flexible current sensor that you can attach to let you get into the tightest spots.
• Measure even harmonic waveform components using the True RMS method
• Expanded -25 °C to 65 °C operating temperature range
• Connect the CT6280 flexible sensor to measure up to 4199 A in thick or paired wires
• Drop proof design withstands drop from a height of 1 meter

Using 3280 series AC clamp meters: Introduction to functionality and measurement methods
In addition to AC current measurement, these clamp meters rovide voltage and resistance measurement as well as continuity check functionality.
Their compact size, low-profile design, and resistance to both rough handling and extreme temperatures make them essential tools for any electrician.
Using 3280 series AC clamp meters: Difference between mean value and true RMS measurement
Measurements taken with the Hioki 3280-10F (which uses the mean value method) and the the Hioki 3280-20F (which uses the true RMS method) are compared.
Observe the difference between readings from these two types of instruments when measuring a distorted waveform that contains harmonic components such as those produced by inverters and switching power supplies.
Essential for electrical work: A thin card tester that fits in the pocket with all the capabilities of a clamp meter
The 3280-10F delivers all the functionality of a clamp meter and card tester in the form factor of the latter. In addition to current measurement, this single instrument delivers voltage measurement, continuity check, and resistance measurement functionality.
A tough, pocket-size clamp meter with an operating temperature range of -25°C to 65°C
The 3280-10F inherits the drop-proof durability of the previous 3280-10 (making it able to withstand being dropped onto concrete from a height of 1 m) and expands that instrument’s operating temperature range to -25°C to 65°C (from the previous 0°C to 40°C). As a result, it can be used in even harsher environments.
