1) When current is a trigger, the instrument operates in the same manner as in
the CURRENT setting for TRIGGER.
2) When force or external input is a trigger, the instrument operates in the
same manner as in the FORCE or EXTERNAL setting for TRIGGER.
3) When force trigger or external trigger is a trigger, the instrument operates in
the same manner as in the FORCE (EXT) or EXTERNAL (EXT) setting for
TRIGGER. Note, however, that the instrument starts measurement only upon
input of current or force (or external input).
• FORCE
The instrument performs measurement each time a force signal is input,
showing the measured values and waveforms.
The internal processing time varies depending on the force and current flow
time. As a result, the internal processing may not be complete before next
measurement. To pass multiple current pulses, refer to PULSE MODE in the
BASIC SETUP (2) screen.
• EXTERNAL
The instrument starts measurement each time an external input voltage (±10
V) or external input current (4 to 20 mA) is input, making an OK/NG
judgment and showing the measured value and waveform.
The internal processing time varies depending on the external input and
current flow time. As a result, the internal processing may not be complete
before next measurement. To pass multiple current pulses, refer to PULSE
MODE in the BASIC SETUP (2) screen.
• REAL TIME
The instrument makes measurement constantly. Force, external input or
displacement is measured at intervals of half a second. To perform
measurement, select FORCE REAL TIME, EXT REAL TIME or DIST REAL
TIME in the VIEW screen. Measurement stops when MEAS is changed to
PROG.
• DISPLACEMENT (EXT)
*1
The instrument measures displacement each time a displacement trigger of
the external input signal is input. The internal processing time varies
depending on the current flow and displacement measurement time. As a
result, the internal processing may not be complete before next
