Simultaneous measurement of demand and harmonics for up to 4 circuits.
The Clamp-On Power HiTester 3169-01 is a clamp-type power meter that can handle single-phase lines to three-phase four-wire lines with just one device. In addition to basic measurements such as voltage, current, power, power factor, and cumulative values, it can simultaneously perform demand measurements and harmonic measurements, which are important for power management and energy-saving measures.

basic information
◆Supports up to 4 power line circuits (common voltage) It can accommodate various measurement lines for 4 circuits (single-phase 2-wire), 2 circuits (three-phase 3-wire), and 1 circuit (three-phase 4-wire) with a single unit. ◆Rich measurement functions Voltage, current, power (active/reactive/apparent), cumulative power, power factor, frequency, and more can be measured simultaneously. Additionally, in the three-phase 3-wire (3P3W2M) mode, it can display 3 voltages and 3 currents with 2 voltage/current measurements. In the three-phase 4-wire (3P4W4I) mode, it can display neutral line current with 4 current measurements. ◆Combines power management and harmonic management Equipped with a harmonic measurement function compatible with three-phase lines. It allows simultaneous harmonic measurement and demand measurement, enabling both power management and harmonic management. ◆Supports polarity indication and reactive power measurement methods Power factor and reactive power measurements include polarity indication for lagging/leading. Additionally, reactive power measurement methods can be selected, and effective power factor and power ratio power factor can also be displayed. ◆0.5A to 5000A range available It can accommodate measurements from large currents and large diameter wires using 7 types of clamp current sensors from the CT terminal. ◆High-speed D/A output available The 3169-01 is equipped with a 4-channel high-speed D/A output. It can provide analog output based on the effective value for each cycle.
