Using 3280 series AC clamp meters: Introduction to functionality and measurement methods
In addition to AC current measurement, these clamp meters provide 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.
A pocket clamp meter that can use flexible sensors
When connected to an optional flexible current sensor, the 3280-10F can be used to measure the current flowing in pairs of wires or in tangled or complexly routed wires around which it was not possible to apply a clamp-on sensor in the past.
Hioki AC CLAMP METER 3280-10F
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.
Hioki AC CLAMP METER 3280-10F
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.
