4-Terminal Measurement Digital Multimeter with ±0.01% DCV Accuracy for High Precision Bench Testing
Hioki benchtop digital multimeters (DMMs) are high precision 5-1/2 digit meters that sample 300 times/second. The 3239 Series measure using the 4-terminal resistance measurement method, and come with a comparator function that is especially useful for production lines.
Key Features
• Multi functional and high precision model, with 4-terminal resistance measurement function • High-speed 3.3msec comparator for production line use • Comparator function with open-collector output, beep sound, or LED display • Built in RS-232C interface and External control I/O, or added GP-IB interface (-01 model)
Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year) *Basic accuracy is when sampling rate is “Slow”.* Regarding DMM accuracy: Due to the many ranges and functions available in a DMM, only the basic accuracy is indicated for reference. Please refer to the individual catalogs for detailed accuracy information.
