Timing Chart
7.2 Timing Chart
The each signal level indicates the ON/OFF status of a contact. In the current source
(PNP) setting, the signal level is the same as the voltage level of EXT.I/O terminal. In
the current sink (NPN) setting, the High and Low voltage levels are reversed.
Set the signal before starting a test to control the measurement conditions at the EXT.I/O
terminal (LOAD0 to LOAD3). The measurement conditions cannot be changed during tests.
IMPORTANT
When the START signal is input after the test voltage is changed, a time of up to
500 ms is added to detect the START signal.
Example
When the test voltage is changed by using the LOAD signal
When the test voltage is changed by using the RS command
Continuous test mode timing chart (1)
When the test duration setting (TIMER) is OFF and the measurement is performed by the /START
signal or /STOP signal input from EXT.I/O or when the test duration setting (TIMER) is OFF and
the measurement is performed by the START key or STOP key on the panel
