| Power Parameters | |||
| Your choices are... | |||
| Wattage | Devices measure system power in watts (W). | ||
| VA | Volt amperes (VAs) are a unit of measure for the current in a circuit multiplied by the voltage of that circuit. | ||
| VAR | Volt ampere reactives (VARs) are a unit of measure for specifying the reactive component of volt amperes (VAs). | ||
| Demand | Demand is the amount of power used in the system being tested. | ||
| Peak Demand | Peak demand is the maximum amount of power used in the system being tested. | ||
| Other | Other unlisted, specialized, or proprietary power parameters. | ||

| |||
| Power Quality Parameters | |||
| Your choices are... | |||
| True RMS Voltage | RMS voltage is obtained by dividing the peak voltage by the square root of 2. | ||
| True RMS Current | RMS current is obtained by dividing the peak current by the square root of 2. | ||
| Harmonics | Current and voltage harmonics can cause problems such as the excessive heating of wiring, connections, motors, and transformers. Harmonics can also cause the inadvertent tripping of circuit breakers. | ||
| Total Harmonic Distortion (THD) | Total harmonic distortion (THD) indicates the RMS voltage equivalent of total harmonic distortion power, as a percentage of the total output RMS voltage. | ||
| Power Factor | Power factor is the ratio of actual power to apparent power. | ||
| K-Factor | K-Factor is a numeric value that accounts for both the magnitude and frequency of the component of a current waveform. It is used to indicate that a full-rated transformer is specifically designed to handle non-linear loads. | ||
| Other | Other unlisted, specialized, or proprietary power quality requirements. | ||

| Data Interfaces | |||
| Your choices are... | |||
| GPIB / HPIB | General purpose interface bus (GPIB) is designed to connect computers, peripherals and laboratory instruments so that data and control information can pass between them. It is also known as IEEE 488 or HPIB, and is electrically equivalent to IEC 625 bus. | ||
| RS232 / RS485 | RS232 and RS485 are standard serial interfaces. | ||
| USB | Universal serial bus (USB) is a four-wire, 12-Mbps serial bus for low-to-medium speed peripheral device connections to personal computers (PC), including keyboards, mice, modems, printers, joysticks, audio functions, monitor controls, etc. | ||
