These multimeters are rugged, extremely reliable, and highly accurate, ideal for applications that require high precision measuring, 73401 can be used for many types of situation such as electrical work, maintenance and R&D. IR communication allows easy management of measured data. They have basic dc voltage accuracy of 0.02 or 0.04% c/w a 51 segment bargraph, a continuity buzzer, a diode check and an auto-power off feature. |
