11.3 Inputting a Pulse Signal
154
This section describes how to input a pulse signal from an external
source.
After configuring scaling (coefficient), sub-unit, and unit (five byte
characters) settings, you can convert an input pulse signal. After
recording and measurement are started, pulse measurement
starts, and pulse input values are saved for each save interval.
No-voltage contact input
Counted when terminals change from shorted to open.
Voltage input
Counted when the voltage level changes to high.
11.3 Inputting a Pulse Signal
To avoid electrical hazards and damage to the instrument, do
not apply voltage exceeding the rated maximum to the pulse
input and output terminals (45 V DC).
When using a current only wiring, pulse input cannot be mea-
sured.
