ZENER DIODE TESTER
ZT-70DL
ZT-70DL is a diode tester for Zener Diode. It is designed to easily interface to machine handler.
Test items include VF, IR, VZ, ZZT and ZZK. The dynamic impedance ZZT and ZZK is tested by reverse bias the diode with the specified IZ, IZK (DC) plus a 1KHz AC current which the RMS amplitude is 10% of the IZ, IZK. The 1KHz AC voltage on the diode (RMS) is measured and divided by the AC current value (RMS) to calculate the dynamic impedance ZZT, ZZK. The test result can be classified to 7 bins (Bin 1 to 5, NOGO and CONTACT).

Test condition data settings are entered from front panel keyboard. The display is a 16 line x 40 char LCD display. There are 4 display pages. Page 1 is for test condition setting & test results display. Page 2 is for classifying condition. Page 3 is for interface setting with machine handler.
