Key features: the instrument uses a 320 x 240 dot-matrix LCD display with multi-screen menu operation and directly measures single-phase or three-phase voltage RMS, current RMS, three-phase reactance, three-phase inductance, total active power and frequency. The measuring range can be extended with PT and CT instrument transformers, and primary voltage or current values are displayed directly according to the set PT and CT ratios. The 5 A current channel has a built-in 6 A over-current fuse.
Operation: the test date and the reactor serial number can be set and are latched on power-down. During measurement the display can be switched between phase voltage and line voltage. A micro thermal printer and an RS232 interface are provided.
Technical data: the working supply is AC220V±22V at 50Hz±0.25Hz. Measuring ranges are voltage 0-800V, current 5 A channel 0-5 A / 50 A channel 0-50 A / 100 A channel 0-100 A / 200 A channel 0-200 A, and frequency 45 Hz-65 Hz.
Measuring accuracy is ±(0.1% of reading + 0.1% of range) for voltage, ±(0.1% of reading + 0.1% of range) for current, ±(0.2% of reading + 0.2% of range) for reactance, ±(0.2% of reading + 0.2% of range) for inductance, ±(0.2% of reading + 0.2% of range) for power and ±(0.2% of reading + 0.2% of range) for frequency.
