Two-Channel Digital Multimeters for Synchronous and Parallel Measurement
The ADCMT 7352A and 7352E combine two independent measurement channels with twin A/D converters, enabling synchronous measurement without switching between channels.
Channel A supports DC voltage/current, AC voltage/current, resistance, frequency, diode, and continuity measurements, while Channel B supports DC voltage/current and AC current measurement. Temperature measurement is also available through the rear TEMP input.
Twin A/D Converters
Independent Ach and Bch measurement
2-Channel Synchronous
Measure two functions without channel switching
10 pA to 10 A
Wide current measurement capability across Ach and Bch
Up to 140 rdgs/s
High-speed single-channel measurement
The independent channel architecture allows parallel measurements such as voltage/current, voltage/temperature, current/temperature, and AC/DC measurements while reducing the influence between channels.
The 7352A provides USB, GPIB, and RS-232 interfaces for system integration, while the 7352E provides USB for a simpler system configuration.

Twin A/D Converter Architecture
Independent A/D converters for Channel A and Channel B enable synchronous two-channel measurement without switching measurement functions between the channels.
Independent Two-Channel Measurement
Channel B is electrically independent from Channel A, supporting accurate parallel measurement even when a potential difference exists between the two channels.
Wide Current Measurement Range
Channel A supports current measurement from 10 pA to 2 A, while Channel B extends measurement up to 10 A.
High-Speed Measurement
The series supports up to 140 readings per second for single-channel measurement and up to 123 readings per second for two-channel synchronous measurement.
Multiple Measurement Functions
Measure combinations of voltage, current, resistance, AC signals, frequency, and temperature for component, power-unit, and system evaluation.
Flexible System Interfaces
The 7352A includes USB, GPIB, and RS-232 interfaces, while the 7352E provides USB connectivity for simpler measurement systems.
