The HT5156 is a bench-type, dual-display digital multimeter with a price well worth its value. It provides a broad range of features and measurement functions which meet various requirements in manufacturing and R&D environments.
The 600,000 counts HT5156 provides real-time measuring and readback function. It also features high brightness/contract VFD, 4-wire resistance measurement technique and 0.02% DCV measuring accuracy. For those who need to control and take preset measurements with a PC, the built-in USB and RS-232C interfaces provide an easy connection between the PC and DMM. The USB and RS-232C interfaces can be controlled remotely via industry standard SCPI commands, which ensure an easy integration with different programming environments.
