The ADCMT 7352A and 7352E are 5½-digit digital multimeters with twin A/D converters for fully independent, two-channel synchronous measurement. Measure voltage, current, resistance, frequency, and temperature combinations with current capability from 10 pA to 10 A.
The ADCMT 7352A and 7352E combine two independent measurement channels with twin A/D converters, enabling synchronous measurement without switching functions between channels.
Channel A supports DC voltage and current, AC voltage and current, resistance, frequency, diode, and continuity measurements. Channel B supports DC voltage and current plus AC current measurement. A separate rear TEMP input supports K- and T-type thermocouples.
The isolated channel architecture supports parallel combinations such as voltage and current, voltage and temperature, current and temperature, or AC and DC measurement while minimizing interaction between channels.
The 7352A includes USB, GPIB, and RS-232 interfaces for R&D and production systems. The 7352E provides USB connectivity for a simpler system configuration.
Independent A/D converters for Channel A and Channel B enable synchronous two-channel measurement without switching measurement functions.
Channel B is isolated from Channel A, helping maintain measurement accuracy even when a potential difference exists between the channels.
Channel A measures current from 10 pA to 2 A, while Channel B provides measurement up to 10 A.
Measure at up to 140 readings per second in single-channel operation or up to 123 readings per second during two-channel synchronous measurement.
Measure combinations such as voltage and current, voltage and temperature, current and temperature, or AC and DC signals with one instrument.
The 7352A includes USB, GPIB, and RS-232 interfaces. The 7352E provides USB connectivity for a simpler system configuration.
