Setting Measurement Conditions (basic settings)
External trigger input method
There are the following three types of input method for a trigger.
• Touching the TRIG key on the screen to manually apply the trigger causes the instrument to perform one
measurement.
Measurement screen SET screen
• Input via EXT I/O: Measurement is performed once each time a negative logic pulse signal is applied. See
"9.1 External Input/Output Connector and Signals" (p. 162).
• Input from interface: Measurement is performed once when
*TRG
is transmitted.
Refer to the Communications Instruction Manual on the bundled LCR Application Disc.
Trigger delay (inserting a delay between the trigger and measurement)(Common)
The delay time period from input of the trigger signal to measurement can be set.
With this function it is possible to ensure that testing is started after the connection condition of the
object being tested and the test cables has stabilized.
The setting applies to both AC and DC measurement.
See "Trigger delay and Trigger synchronous output" (p. 64).
For more information about trigger delay timing, see the gures in "Measurement and data acquisi-
tion timing" (p. 65).
Screen display method (For more information, see p. 24.):
