B7-68 voltmeter

B7-68 is the portable desktop voltmeter and differs in high characteristics on the accuracy of measurements, with expanded functional and service opportunities. The high-contrast two-lower case LED indicator used in the device displays not only results of measurements, but also the additional alphabetic and symbolical information characterizing the current operating mode of the device.

High precision of measurements of variable tension and currents is realized in the voltmeter due to calculation of true mean square values. Existence in the device of the built-in RS-232C and RS-485 interfaces allows to work to the device with an indication format 4,5 categories and display of results on the screen of the display of the personal computer. Besides, the RS-485 interface provides a possibility of connection to 32 B7-68 devices according to the 2-wire scheme to the computer, uniting them in the multichannel automated measuring system of collecting and data processing.
