The DT 616 tester is used for series measurement of diodes. It enables the testing of standard diodes, unipolar and bipolar Zener diodes:
1. Forward voltage VF
The voltage drop at the DUT is caused by a test current which is adjustable from 0.1 up to 20 A. It is measured at a resolution of 1 mV.
2. Zener voltage VZ
The test voltage is from 0 to 700 V. The measurement current ranges from 1 up to 500 mA.
3. EZ-measurement
For EZ measurement, the test current is being varied by ± 10%. The subsequent voltage change is measured.
4. Breakdown voltage VBR
The VBR-test voltage is adjustable in a range from 10 up to 2,500 V.
The tolerance range is set by a minimum and a maximum limit. The test voltage is limited to an adjusted maximum VBR +100 V.
5. DVBR-measurement
After the first VBR-measurement a second measurement cycle is started. During the first cycle an internal compensation voltage is measured, which is now used as reference. The DVBR-measurement can be implemented at a higher resolution.
6. Reverse current IR
Reverse current measurement is determined by applying a blocking voltage and monitoring the current value.
