Digital Multimeter
7351A / 7351E / 7351E+03
- Highest-throuput in the class
FAST 140 readings/s (19999) - MED 40 readings/s (199999)
- High measurement accuracy of 110 ppm (2 VDC range)
- Various interfaces
USB as standard
GPIB, trigger signal input, complete signal output - SCPI commands compliant (7351A)
The 7351A, the 7351E and the 7351E+03 are 5½-digit digital multimeters for a wide range of measurement applications covering use in R&D and production lines. The 7351A is equipped with GPIB and USB interfaces, the 7351E with a USB interface and the 7351E+03 with USB and RS232 interfaces. The 7351 series realize 46 readings per second (60 Hz) at integration time of 1 PLC that is the highest sampling rate in this class, contributing to the takt time reduction and the quality improvement in production lines.
Features
Excellent measurement stability
Since the 7351 series have very small dispersion in the voltage and current functions, they are effective in micro voltage or current measurement.
Motor driving current measurement
The driving current of stepping motors can be easily measured by using the DC current measurement function of the 7351 series.
Measurement time
The sampling rate of digital multimeters per 1 PLC is very important for system use to perform high-speed measurment having an induction noise removal function. The 7351 series realize 46 readings per second (60Hz) that is the highest sampling rate in this class.
