9−4. RS−422 interface
Warning ● The error code will be sent against the command from the host during
other than the mode of Measurement mode, such as in the Calibration
mode, Fine adjustment mode, and Setting mode.
● When CHECK switch is ON status, take care of the following points.
1
When CHECK switch will be ON status, the instrument will be
out of the Measurement mode, but RS−422 interface will make
response to the command from the Host.
2
By ON operation of CHECK, there may be a case that display will
show as “OL” error. At the same time, executing the reading
command for load makes the “OL” transmitted to the Host.
● The sending terminal is low impedance for 1 ms after finishing
sending in the instrument. Therefore, to prevent from competing with
other instruments, apply the sending wire (SDA, SDB) at the intervals
of 1ms or more.
