SHORT TIME: setting the Short test time, the left 5 digit monitor display the
"SHORT" ,the right upper 5 digit monitor display the TIME and right lower monitor
display "100ms" , the range is 100ms to 10000ms.
The short test will be no time limitation when setting to CONTI until press
"START/STOP" key to stop the short test.
Note: TURBO ON state, the test time up to 1000ms.
V-Hi: Short test voltage check upper limitation setting, the Left 5 digit monitor
display the "SHORT" ,the right upper 5 digit monitor display the "V-HI" and right
lower monitor display setting value, the unit is "V". The range is 0.01V to 500.00V.
V-Lo : Short test voltage check lower limitation setting, the Left 5 digit monitor
display the "SHORT" ,the right upper 5 digit monitor display the "V-Lo" and right
lower monitor display setting value, the unit is "V". The range is 0.01V to 500.00V.
Once the test parameters have been entered the test is started by pressing
The red START/STOP button while the SHORT PRESS START text is
displayed. During the test the bottom LCD will show run and the actual short
Current will be displayed on the right upper LCD.
Note 1:
The message PASS END will be displayed if the measured voltage
levels stays within the V_Hi and V_Lo threshold levels during the test
Note 2:
The message FAIL END will be displayed if the measured voltage levels
falls outside the V_Hi and V_Lo threshold levels during the test. The NG
flag will also illuminate.
Note 3:
If continuous short time is selected the test is ended by pressing the red
START/STOP button.

The OPP parameters setting:
The OPP allows the parameters of an Over Power Protection test to be entered.
The OPP test will ramp up the load power in steps to validate the Device under
Test's (DUT) protection and behavior. A voltage threshold level can be set. If the
Voltage measured during the test is lower than the set Threshold voltage then the
Test will fail and the display will signal OPP ERROR. Similarly a power threshold (P
STOP) can be set. If the measured power reaches the P STOP threshold the test
Will be discontinued and the OPP ERROR message will be displayed.
Pressing the Item key once will cause the button to illuminate. The message
