GW Instek GPM-8213 power meter is designed specifically for single-phase (1P/2W) AC power supply’s power measurements. Powerful features, including 4” TFT LCD, five-digit measurement display, 19 power measurement parameters, integral measurement function, high-accuracy voltage/current/power measurement capabilities, front/rear panel input terminals, and various communications ports, are to facilitate users with clear, convenient, and accurate power measurements. GPM-8213 provides as many as 19 power measurement parameters, including voltage (Vrms/ V+pk / V-pk), current (Irms/ I+pk / I-pk), frequency (VHz/ IHz), power (P/ P+pk / P-pk), crest factor (CFV/ CFI), apparent power (VA), reactive power (VAR), power factor (PF), phase angle (DEG), total harmonic distortion (THDV/ THDI), high-accuracy voltage/current/power measurement capabilities (reading: ±0.1%; level: ±0.1%). The advantages of TFT LCD havebeen efficiently deployed to simple mode and standard mode. Simple mode displays conventional power meter’s four measurement parameters to meet the requirement of accuracy and clarity for the test on manufacturing process. Standard mode extends the display to the maximum of 8 measurement parameters (2 major measurements + 6 monitor measurements) to satisfy the various measurement application requirements of R&D, design, and quality verification. For DUT requiring IEC 62301/EN 50564 standby power consumption test, GPM-8213 provides the optimal measurement supports, including test frequency bandwidth of DC~6kHz, the minimum current level of 5mA (resolution: 0.1uA), power measurement resolutions (1uW for minimum current and voltage levels; 1mW for maximum current and voltage levels), crest factor reaching 3 (half range reaching 6), and measurement of total harmonic distortion (at least 13th orderpower harmonic). For large voltage /large current measurement applications of general power measurement, GPM-8213 provides PT / CT rate function to collocate with external potential transformer or current transformer to meet the measurement requirements. With respect to data retrieval and storage, the standard RS-232C/ USB interfaces (virtual COM)/ LAN can be utilized to edit and retrieve programs or the optional GPIB interface (installed by manufacturer) can be selected to meet users’ automatic test system requirements. |
Two Display Modes GPM-8213 provides two display modes so as to maximize users’ measurement effectiveness. Standard mode: simultaneously displays 8 measurement parameters (2 major measurements + 6 secondary measurements) and related measurement setting parameters; ideal for R&D, design, and engineering verification. Simple mode: displays four measurement parameters; ideal for production tests. |
Variety of Measurement Parameters Comparing with products of the same category, GPM-8213 provides more diverse measurement items and functions, including voltage, current, frequency, active power, apparent power, reactive power, power factor, crest factor, and total harmonic distortion measurement. GPM-8213 also features the integral measurement function for DUT’s power or current time. Users can set a time period to execute the transient power integration and divide the result by timeto receive DUT’s average power. |
Optional Measuement Capabilities For IEC 62301/EN 50564 standby power consumption test requirement, GPM-8213 can fully meet the demand by its features, including measurement frequency bandwidth of DC~6kHz, minimum current level of 5mA (resolution: 0.1uA), power measurement resolutions (1uW for minimum current and voltage levels; 1mW for maximum current and voltage levels). Beyond that, time resolution for integral measurement is one second. With respect to large power measurement, userscan utilize terminal on the rear panel to conduct 600V / 20A measurement. Users can also use external potential transformer/current transformer for measurement and collocate with PT/CT to set multiplying factor (1~9999) to change readings to the original input voltage or current values without the trouble of additional calculation. |
