2.3 Recording Functions
Chart Speed
The speed at which the chart moves when performing trend recording can be selected from any
value between 1 to 1500mm/h.
Two types of chart speeds can be set. When you are not using the Event/Action function, which
will be described later on in this manual, chart speed 1 will be valid. When the Event/Action
function is being used, you can select whether chart speed 1 will change to speed 2 according to
the event status.
Recording Mode
Two types of recording modes are available; analog trend and logging mode. The default setting
is analog trend mode.
Analog Trend Mode (refer to the next page for a recording example)
Trend Recording (Dot recording)

recording conditions consist of the following.

• recording interval (refer to page 2-8)
• recording span (refer to page 2-9)
• recording zone (refer to page 2-9)
• partially expanded recording (refer to page 2-10)
• interpolation function (refer to page 2-10)
Digital Printout
Measurement data will be printed as numerical values. Digital printout conditions consist of the
following.
• channels to be recorded
• recording interval (refer to page 2-8)
• the number of channels to be recorded on the same line (refer to page 2-7)
Logging Mode
In this mode measurement data are only printed as numerical values. Logging recording
conditions consist of the following.
• channels to be recorded
• the recording direction (vertical or horizontal)
