Unit Measure Channel Trigger Alarm Calculation System

Alarm (Alarm Output)
This chapter describes how to set alarm conditions for each
measurement channel.
You can have the instrument sound a tone or output an alarm
signal to an external device when measurement data satisfies
the set condition.
For example, you can output an alarm when the recorded
temperature becomes too high.
Alarm signals can be outputted from the external control
terminals to external devices.
See “8 External Control (EXT. I/O)” (p. 173).
If an alarm condition is satisfied when measurement starts,
the alarm will be output immediately.

Setting shared alarm conditions for all channels .................................... p. 130
Configuring channel-specific alarm settings ........................................... p. 133

IMPORTANT
The logger is unable to detect alarm conditions when there is no data due to an interruption in
communication with wireless modules. However, it can detect the alarm condition of the wireless
module communication interruption.
When communication is reestablished with the wireless modules, the logger will restore data and
detect alarm conditions.
