Specifications:
The document outlines the specifications for a power meter capable of measuring both AC and DC currents with a wide range from 0.001W to 16kW. It includes features such as a standby power resolution of 0.001W, peak factor display, and harmonic analysis up to 50 orders. The device can store up to 1000 measurement data sets and has a fast auto-ranging capability.

Standard Accessories:
Included are a power cord, electronic user manual on CD, RS232 connection cable, F71201 test box, TL218 crocodile clip adapter, and TL208 2mm test probe.

Optional Accessories:
GPIB connection cable.

Measurement Parameters:
Voltage (Vrms, Vdc) range from 0.1V to 600V, current (Irms, Idc) from 0.1mA to 20A, power (W) from 0.01W to 16kW, power factor (PF) from 0.000 to ±1.000, phase angle (Deg) from -180° to +180°, total harmonic distortion (THD) from 0.01% to 999.99%, and frequency (Hz) from 15Hz to 100kHz.

Analysis Capabilities:
The power meter uses voltage or current to obtain a stable fundamental frequency for analysis, with a frequency range of 45Hz to 440Hz. It supports FFT data length of 1024 and 32-bit data format. Measurement items include total harmonic distortion, voltage and current distortion percentages, wattage, and phase angles for up to 50 orders.

Model Specifications:
Models 7110 and 7120 are detailed, with input power ranging from 100 to 240Vac at 50/60Hz. The display is a seven-segment type, and interfaces include RS-232 and optionally GPIB. The storage memory can hold 6 sets of data, and the operating environment is specified at 23℃±5℃ with 20-80% RH.

Measurement Accuracy:
Accuracy varies with frequency, with specific tolerances outlined for different frequency ranges. For example, for frequencies between 15 Hz and 45 Hz, the accuracy is ±(0.1% of reading + 0.4% of range). Additional conditions apply for AC and DC measurements, including offset errors and phase angle impacts on power accuracy.

Additional Features:
The document also details the use of digital filters, sampling rates, and ADC resolution. It specifies the conditions under which certain filters should be turned off for optimal accuracy, particularly for frequencies above 200Hz.
