logF A B F A B
logF logA logB F logA logB
logF log(-A) logB F log(-A) logB
logF logA log(-B) F logA log(-B)
logF log(-A) log(-B) F log(-A) log(-B)
logF logR --- F logR ---
θ logR ---
●Scale unit
Gain (abstract number)/impedance (  , S)
●Voltage and current input
CH1 fixed to voltage, CH2 fixed to current
●Current shunt input conversion coefficient
0 to 1.0E+6 (resolution 5 digits or 0.01E-9), phase reverse feature
●Open/short correction feature
Open correction Short correction Correction formula
OFF ON Zx=Z-Zs
ON OFF Zx=Zp×Z÷(Zp-Z)
ON ON Zx=Zp×(Z-Zs)÷(Zp-(Z-Zs))
Zx Correction calculation result
Z Measured value (CH1/CH2)
Zs Short correction data (CH1/CH2)
Zp Open correction data (CH1/CH2)
Calculation by the aforementioned formula applies regardless of the [ANALYSIS MODE]
(analysis mode) setting.
●Maximum/minimum search feature
Search item Y1-axis maximum, Y1-axis minimum, Y2-axis maximum,
Y2-axis minimum
Search method When the function key relevant to the search item is pressed when
data marker is being displayed, the vertical axis parameters are
automatically searched and the marker moves accordingly
