Markings
Improper handling or use can lead to injury to the user or damage to
the instrument. This symbol appears on the instrument to indicate that
the user must refer to the user’s manual for special instructions. The
same symbol appears in the corresponding place in the user’s manual
to identify those instructions. In the manual, the symbol is used in
conjunction with the word “WARNING” or “CAUTION.”
WARNING Calls attention to actions or conditions that could cause serious or fatal
injury to the user, and precautions that can be taken to prevent such
occurrences.
CAUTION Calls attention to actions or conditions that could cause light injury
to the user or cause damage to the instrument or user’s data, and
precautions that can be taken to prevent such occurrences.
Note Calls attention to information that is important for the proper operation
of the instrument.

Using the Log scale Function
Log Scale Display Function
You can apply a logarithmic voltage that has been converted from a physical value to the
recorder, and then use the log scale (logarithmic scale) to display and record the physical
value. The recorder supports three types of input signals.
• Logarithmic Input
This is referred to as “Log input”. Log input is input in which the voltage corresponds to
logarithmic values of physical values.
• Pseudo Log Input
This is referred to as “Pseud-log input.” This input supports pseudo logs.
A pseudo log signal is a voltage obtained by summing the one’s digit of the voltage
representing the exponent of the logarithmic data and the decimal digits of the voltage
representing the mantissa.
• Input That Is Linear on a Logarithmic Scale
This is referred to as “Linear-Log input.” Linear log input is input in which the voltage
values correspond to the logarithmic values of physical values at each decade division
(for example, 1 × 102) and in which, within each decade, the voltage values correspond
linearly to physical values.
On the trend display, the recorder displays waveforms with the log scale. Digital values are
displayed as exponents (for example, 1.2E+03).

Restrictions
Partial
You cannot set the partial display on a channel that is set to log scale.
Differential Computation between Channels
If you set the reference channel of a differential computation between channels to a channel
that is set to log scale, an error will be returned as the measured result of the differential
computation between channels.
Computation Channels (/MT option)
Do not include channels that are set to log scale in a computation channel expression.
If you include these channels, an error will be returned as the measured result.
Report Function (/MT option)
You cannot create reports for channels that are set to log scale. An error will be returned as
the result of report computations on channels that are set to log scale.
Manual Sampled Data
For channels that are set to log scale, the data is stored using the “mantissa + exponent”
format, the same format as that of digital values on the recorder.
Number of Channels Set to Log Scale
Keep the number of channels set to log scale no greater than 300.
When there are many channels set to log scale, log scale processing may not finish within
the scan interval and may cause computation data dropouts.
