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 3280-20F 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.

Essential for electrical work: A thin card tester that fits in the pocket with all the capabilities of a clamp meter

The 3280-20F 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.
