Ground Bond Tester 19572 User’s Manual
4-2
output and each judgment function start simultaneously.
Cal-Enable: Calibration switch. This key is only for calibration before exiting factory. A
non-professional personnel using this function is prohibited or may cause the
product malfunction.
UPDATE: This key is for updating the program before exiting from the factory.
Non-professional is prohibited to use this function, or may cause the tester
malfunction.
Function Keys: Function keys F1 ∼ F4, there are different functions under different display
menus. The corresponding function key is at the right side of display. If
the description part is blank, it means the corresponding function key is
invalid.
Terminal Area
Drive (+): Positive electric potential of mass current output.
Sense (+): The grounding impedance testing positive terminal.
Sense (-): The grounding impedance test negative.
RTN/LOW: Common test terminal. It is mass current output negative terminal also is low
potential terminal. This terminal is almost equivalent to chassis ground terminal.
4.2 Rear Panel
(1) REMOTE I/O PORT 1: The remote input/output port 1.
START : Start test signal input terminal.
STOP : Stop test signal input terminal.
INTER LOCK : Output high voltage only when this two terminals are short-circuited.
UNDER TEST : When the tester is under testing, this output terminal will be short-circuited.
Control external signal by using this short condition. The junction
specification 30V AC or 60V DC current is less than 0.3A action time.
The tester is under testing until be stopped.
PASS : When the tester judge DUT as pass, this output terminal will be
short-circuited. User specifies the time of short circuit. Control external
signal by using this short circuit condition. The junction specification 30V
AC or 60V DC current is less than 0.3A action time. The product judge as
pass until is stopped.
