  • New measurement environment by twin A/D converters
  • Double the throughput by Ach/Bch synchronous measurement
  • Wide dynamic range of 5½ digits on both Ach and Bch
  • Wider current measurement range and parallel measurement with voltage or temperature
    A ch: 10 pA to 2 A
    B ch: 100 µA to 10 A
  • A variety of interfaces
    7352A: USB, GPIB, RS-232
    7352E: USB

 

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 10 pA to large current of 10 A.
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.

Evolution from Dual to TWIN

Features


Synchronization

Improve the system throughput with minimum dispersion?

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.

High accuracy

Measure Bch as well as Ach highly accurately?

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. 

Low current

Measure much lower current?

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. 

System configuration

Build up a system easily?

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.

Measurement Time

The maximum sampling rate is 140 readings/sec for 1-channel single measurement and 123 readings/sec for 2-channel synchronous measurement. The sampling rate per PLC at which noise rejection is possible is 46 readings/sec for single measurement and 40 readings/sec for synchronous measurement that are the highest rate in this class.
