■ FunctionsThatCannotBeUsed
• Partial expanded display
Partial expanded display cannot be specified on a
channel in LOG input mode.
• Difference computation between channels
• There is no limitation on setting a channel in LOG
input mode as a reference channel in a difference
computation.
• However, if such difference computation is executed,
the measured result of the difference channel is
error.
• Calibration correction function
Calibration correction cannot be specified on a channel
in LOG input mode.
■ NumberofGrids(NumberofDivisionsoftheScale
Display)
• The number of grids can be set in the range of 4 to 12
or auto (same as the standard model).
• If the number of grids is set to auto on a target channel
set to LOG range, the number of grids is equal to the
number of decades. The display shows a LOG grid in
this case.
• Channels set to LOG input mode is automatically set to
LOG scale.
■ CommunicationOutputandBinaryDataOutput
Format
• The binary data is an A/D normalized value of the
channel set to LOG.
• Measured data output (FD command)
• FIFO data output (FF command)
(Example)
If the input is 3.000 V measuring in the 6-V range, the
binary data is 10000 (0x2710).
• If the measured result is -OVER, the value is set to
0x8001. If the measured result is +OVER, the value is
set to 0x7FFF.
Note
Converting from binary data to LOG value
1 The binary data is output in A/D normalized value. The
A/D normalized value is a scaled value taking the full
span value of the range to be 20000.
The full span value of the range is the maximum value
that can be set in the range. It is 6 V in the 6-V range.
For example, the A/D normalized values in the 6-V
range are as follows: 6 V = 20000, -6 V = -20000, 1 V =
20000*1/6 = 3333.3.
2 The A/D normalized value is converted to voltage using
the following equation.
Voltage = (A/D normalized value)*(full span value of the
range)/20000
3 The voltage is converted to a LOG value using the
equation given in section 2.1, “Converting the LOG
Input.”
Setting the Number of Displayed Mantissa Digits
1. Press MENU (switch to the setting mode).
2. Hold down FUNC for 3 s to switch to the basic
setting mode.
3. Select Environment > Digits, Time indicate.
4. Set Digits to 2 or 3.
Setup Screen Example for the Number of
Displayed Mantissa Digits
■ Alarm
• Alarm types in LOG input mode
H, L, T, and t only.
• Set the alarm value using a voltage.
• Computing method of alarm values
Computing equation of the digital display value
From Y = 10(SU-SL)*(X-VL)/(VU-VL)+SL
logY = (SU-SL)*(X-VL)/(VU-VL)+SL
X = (logY-SL)*(VU-VL)/(SU-SL)+VL
For a computation example, see Table 2.
• Alarm hysteresis fixed to 0%.
The alarm hysteresis settings specified in the basic
setting mode for the measurement channel are invalid.

■ ManualSampleFunction
• Stored data when a channel set to LOG is assigned
The data is stored in the same format as with the digital
value display (mantissa + exponent).
• Events that cause the manual sampled data to be
divided
If the number of displayed mantissa digits of the LOG
input range is changed, the data file is divided the next
time manual sample is executed.
Measurement and Display Accuracy
■ MeasurementandDisplayAccuracy(Digital
Display)
• Computing method of the display value accuracy
Input voltage : X
Lower limit of
display span
: VL Upper limit of
display span
: VU
Scale lower limit : SL Scale upper limit : SU
Digital display value : Y
1) Converting equation for the input voltage (setting)
• Y = 10(SU-SL)*(X-VL)/(VU-VL)+SL
2) Measurement accuracy of input voltage X (uses the
negative side due to the LOG characteristic)
• Xerr =X – (measurement accuracy of the voltage
range)
3) Hardware error of the display value
• Y’= Y – Yerr
• The difference from the true value Y is hardware
error Y’ when display value Yerr corresponds to
input voltage Xerr.
4) Display accuracy of the mantissa
• Display accuracy = Y’* 1.1 + 1 digit
• Computing example of the display value accuracy
Integration time : 50 Hz
2 V range : Voltage span 0.0000 to 1.0000 V
LOG span : -2 to 3
1) Determine the converting equation for the setting.
Y = 10(SU-SL)*(X-VL)/(VU-VL)+SL
= 10(3-(-2))*(X-0)/(1-0)+(-2)
= 10(5X-2)
2) Determine the measurement error with respect to
the input voltage.
Measurement accuracy of the 2 V range = ±(0.05%
of rdg + 12 digits)
= ±(0.0005*10000+12)
= ±17 digits
Therefore, for an input voltage of 1 V, the value will fall
within the range between 0.9983 V and 1.0017 V.
Since the computation is performed on the negative
side with large error in the LOG characteristics, we
obtain Xerr = 0.9983 V.
3) Determine the hardware error of the display value.
Substitute Xerr, the value determined in 2), into the
equation of 1).
Yerr = 10 (5*0.9983-2)
= 9.8 * 102 (truncate values below the one-
hundredths place)
Since the true value is Y = 1.0 * 103, the error is 2
digits.
Therefore, the hardware error of the display value is
given by Y’ = ±2 digits.
4) Display value accuracy of the mantissa
• As a final error, we add the software error to the
hardware error.
• Software error = Hardware error * 1.1 + 1 digit
• Display value accuracy = ±(2 digits * 1.1 + 1 digit)
= ±(3.2 digits)
The fraction is rounded up. When the mantissa is 2
digits, the display accuracy is ±4 digits.

Simulation Function
Display Freeze Function
■ Specifications
• A function used to stop the updating of the time, trend,
digital values, and bar graph.
• The display freeze function is controlled through the
event action function or communication commands.
• Alarm summary, message summary, and various log
displays are also not updated if they are displayed.
• While the display is frozen, display data is also not
updated.
• Key operation is possible while the display is frozen.
Display operations such as switching the display group
are possible.
• When recovering from the display freeze condition to
normal operation, the trend display is resumed from
where it left off.
“Close” to “Open”
Screen image of the operation
• The time display can be enabled or disabled in the
basic setting mode.
For details, see the “■ Enabling/Disabling the Time
Display” on page 10.
■ EventActionFunction
• You can freeze or activate the display using the event
action function.
The “Display Freeze/Activate” action can be specified
only when the event is set to “Remote.”
• The “Display Freeze/Activate” action operates as a
level action.
• The display freeze action is executed when an
open-to-close event (rising edge) is detected.
• The display activate action (normal operation) is
executed when a close-to-open event (falling edge)
is detected.
Normal operation
Display freezeNormal operation
Close
Open
• Event action functions that do not operate while the
display is frozen
See Table 3.
If a level action such as Memory start/stop is executed
due to a level event such as remote while the display is
frozen, the DX operation may become mismatched with
the event state.
Example)
If Memory start/stop using remote is specified and the
remote control input is switched from closed to open
while the display is frozen, the memory stop operation
is not executed. If display freeze is released in this
condition, the remote control input terminal will be open
even though the memory is in a start condition.
Action Note
Memory start/stop Does not operate while the display is
frozen. Operates after the display freeze is
released.
Memory start Does not operate while the display is
frozen. Operates after the display freeze is
released.
Memory stop Does not operate while the display is
frozen. Operates after the display freeze is
released.
Event trigger Does not operate while the display is
frozen. Operates after the display freeze is
released.
However, the action does not operate if the
event is set to timer or match timer.
Save display data Does not operate while the display is
frozen. Does not operate even after the
display freeze is released.
Save event data Does not operate while the display is
frozen. Does not operate even after the
display freeze is released.

back to the operation screen from the basic setting mode.
• If the power turns OFF and then back ON such as due
to a power failure while the display is frozen (closed
state) through remote control, the display freeze
function is released even if there is no change in the
remote state (remains at the closed state).
• The automatic display revert function does not operate.
The automatic revert timer is restarted when the
display freeze function is released.
