DMI 551

Digital Measuring Instrument

Digital Measuring Instrument DMI 551 is a microprocessor controlled device for measuring AC, DC and Impulse voltages.

Instrument can also be used for firing a generator or a chopping sphere gap and to trigger an oscilloscope or any other measuring device. The triggers can be set for delays in time and in phase.
