The Instek GPM8213 Digital Power Meter, 19 Power Measure Parameters is a high-precision, programmable power meter for use in standby measuring low power devices such as switching power supplies, transformers, power supplies, adapters, and other devices. This model is designed specifically for single-phase (1P/2W) AC power supply's power measurements. Powerful features include 4 in. 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.

The 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), and high-accuracy voltage/current/power measurement capabilities (reading: ±0.1%; level: ±0.1%). Simple mode displays conventional power meter's four measurement parameters to meet the requirement of accuracy and clarity for testing on manufacturing processes. 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 order power 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.

The standard RS-232C/ USB interfaces (virtual COM)/ LAN can be used to edit and retrieve programs.
