start command
Starts pulse
measurement.
• This relay is turned on to measure pulses.
• The command is valid while this relay is
on.

CH1 error reset
command
Resets the CH1 error.
• This relay is turned on to reset the CH1
error.
• The command is valid at the rise of this
relay (off  on).
• The on and off time must be held for at
least 2ms.
