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)
The recording principle is that, according to measurement data and recording conditions, the
correct position on the chart will be decided and on that position the dot will be printed. Trend
recording conditions consist of the following.
• chart speed
• channels to be recorded
• recording color (refer to page 2-9)
• recording interval (refer to page 2-9)
• recording span (refer to page 2-10)
• recording zone (refer to page 2-10)
• partially expanded recording (refer to page 2-11)
• interpolation function (refer to page 2-11)
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 2-9)
• the number of channels to be recorded on the same line (refer to page 2-8)
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)
• recording interval (refer to page 2-9)
