5½-digit DMM with twin A/D converters offering two-channel synchronous measurement
The 7352A and the 7352E are the next-generation digital multimeters equipped with twin-A/D converters that enable fully-independent measurement of two-channel signals. These multimeters are suitable for high-speed measurement, parallel measurement of different functions and multi-channel measurement by configuring a system.
The channel A (Ach) has basic measurement functions including DC voltage/current, AC voltage/current, resistance and frequency measurement functions, while the channel B (Bch) has DC voltage/current, AC current and temperature measurement functions. Thus, higher throughput can be obtained with Ach/Bch synchronous measurement or Ach/Bch parallel measurement of different functions.
Furthermore, the dynamic range of current measurement has been broadened significantly, enabling measurement from low current of 10pA to large current of 10A.
The 7352A is equipped with a RS-232 interface in addition to USB and GPIB interfaces as standard for use in R&D and production lines. The 7352E is equipped with a USB interface as standard for low-cost system configuration.
Twin A/D converters realize synchronous measurement of Ach and Bch functions. Even at the sampling rate per PLC at which noise rejection is possible, two-function measurement data can be obtained without switching the functions, allowing the significant improvement of the system throughput.
Low current measurement
The broadened dynamic range enables measurement of low power consumption. Ach has measurement ranges from 2 µA (10 pA resolution) to 2 A, and Bch has 10 A measurement range (100 µA resolution). Two functions such as current/voltage or current/temperature can be measured with high sensitivity and resolution and these results are dual-displayed.
Since Bch is fully independent from Ach, its measurement is not affected by the potential difference between them. In addition, high-accuracy Bch measurement is available with 5½-digit display. Moreover, this series is capable of high-accuracy parallel measurement of different measurement functions such as voltage/current, voltage or current/temperature, or AC/DC between Ach and Bch.
In building up a system, system interfaces are available for easy connection with a programmable controller. The 7352A is equipped with USB, GPIB and RS-232 interfaces as standard.
