If the TRIO B (F2) button is pressed, programmed, and saved then the corresponding TRIO B (F2) button available in TEST mode will use the limits stored in SPECS mode. Operations Manual: CDT-65A Diode Tester Page 9... - Page 11 To test diodes the operator must have the information from the following table programmed into the tester. The operator can change these settings quickly and easily. These settings can be tailored to meet the specific needs of the diode. Operations Manual: CDT-65A Diode Tester Page 10...

At the top of the setup screen the number of passed and failed diodes since last power up or reset is displayed. CDT-65A Statistical Report Time:………. Date:……… Current Test Mode Diodes PASS Diodes FAIL Diodes Tested Tested by:………………………………………… Operations Manual: CDT-65A Diode Tester Page 13... -
Page 15: Reset
Vdrop= _._ _ _V REVERSE The CDT-65A will automatically switch the test leads internally if the test leads are reversed if the REVERSE function is enabled. When REVERSE is disabled it is not possible to test a diode if the test leads are reversed, this is useful for sorting diodes by polarity. The REVERSE function is off when there is an X through its icon. -
