Log Scale (/LG1)
Item Specifications
Function A logarithmic voltage that has been converted from a physical value is applied to the FX, and then
the FX’s Log scale (logarithmic scale) is used to display and record the physical value.
Input type Log input: Logarithmic input (LogType1)
Log linear input: Input that is linear on a logarithmic scale (LogType2)
Pseudo log input: An input that supports pseudo logs. (LogType2)
Nonlinear log input: An input that supports nonlinear logs on which calibration correction (/CC1
option) is applied.
Calibration correction is performed using voltage values. (LogType1)
Range 20 mV, 60 mV, 200 mV, 2 V, 6 V, 20 V, 50 V, and 1 V
Unitl Up to 6 characters
Scalable range
Log input (LogType1)
1.00E–15 to 1.00E+15 (15 decades maximum)
Lower limit mantissa range: 1.00 to 9.99. Upper limit mantissa range: 1.00 to 9.99.
Scale_L < Scale_U
If the lower limit mantissa is 1.00, the difference between the exponents must be 1 or more.
If the lower limit mantissa is a value other than 1.00, the difference between the exponents must
be 2 or more.
Log linear input/Pseudo Log Input (LogType2)
Lower limit mantissa range: 1.00 to 9.99. Upper limit mantissa range: N/A (the value is the same
as the lower limit mantissa).
If the lower limit mantissa is 1.00, the value must be between 1.00E–15 and 1.00E+15, the
difference between the exponents must be 1 or more, and the maximum decades is 15.
If the lower limit mantissa is a value other than 1.00, the value must be between 1.01E–15 and
9.99E+14, the difference between the exponents must be 1 or more and the maximum decades is 14.
