Key Features
• 12 different measurement functions: DCV/ACV, DCI/ACI, 2W/
4W, frequency/period, diode test, continuity, dB/dBm, etc
• Maximum reading of 120,000 digits
• DCV measurement accuracy up to 0.0035%, resolution 1 uV DCV
•True-rms AC voltage and current measurement, with high
frequency of 300kHz
• Maximum measurement rate:45times/second
• Equal accuracy frequency measurement more than 1 MHz,
minimum resolution of lOuHz
• Good reading stability, high accuracy and high measurement
rate
• High-brightness vacuum fluorescent display (VFD)
• Zeroing (RFL) mode to eliminate residual reading
• 2W and 4W resistance measurement modes selectable
• Built-in mathematics calculation functions: mX+b, %, dB,dBm
•512 readings storage and MAX/MIN/AVER/STD statistics
• HI/IN/LO comparator function
• GPIB and RS-232 interfaces for convenient system
communication
• Calibration performed without opening the cover
• 10 sets of measurement states saved and recalled up
