M3500A is a high-performance, six-and-a-half (6-1/2) digit multimeter with 0.0015% basic voltage accuracy and 0.0020% basic resistance accuracy. In six-and-a-half mode, it can reach 50 readings per second; in the fast four-and-a-half mode, it can reach 2000 readings per second and simultaneously return to the PC or other devices via USB or GPIB interface. M3500A has a wide range of measurements: DC voltage: 0.1μV to 1000V AC voltage (effective value): 0.1μV to 750V (1000V peak) DC current: 10nA to 3A AC current (effective value): 1uA to 3A two-wire and four-wire resistance measurement: 100uΩ to 120MΩ frequency: 3Hz to 300kHz period measurement: 3.3us to 333ms diode measurement: 10uV to 1.2V conduction test: 10mΩ to 1.2KΩ temperature measurement: support various thermocouples and thermistors, temperature range only limited by the sensor.
This manual describes the features and operation of the Keysight M3500A digital multimeter, a six‑digit, high‑precision instrument for voltage, current, resistance, frequency, continuity, and temperature measurements. It explains the front‑panel functions, menu navigation, and how to connect the USB or GPIB interface to a PC.
The document also covers setup procedures, range selection, terminal connections, and calibration steps. Detailed tables list the measurement ranges, accuracy, and limits for each function, as well as special settings such as temperature‑compensated measurements and trigger modes. This manual is written in Chinese.
Use the SHIFT key together with the function button (e.g., SHIFT + DCV for DC voltage) to select the desired measurement mode.
