:CONFigure:COMParator:DC
<numerical value 1>,<numerical value 2>
:CONFigure:COMParator:DC?
<numerical value 1>,<numerical value 2>
<numerical value 1>
= allowable value data (NR3) for normal condition (Upper
limit, when DC is selected)
<numerical value 2> = allowable value data (NR3) for fault condition (Upper
limit, when DC is selected)
Function Command S
ets the allowable value to use when making DC measurements.
The instrument calculates the allowable value by multiplying the numeric value
by the factor, but the factor is set to 100% by the interface command.
The range of numeric values is from 5.000E-06 to 20.00E-03 (unit: A).
The following measurement modes for the B1 and B2 networks provide an
allowable value (upper limit) for AC measured current and an allowable value
(upper limit) for DC.
Sets one allowable value each for normal condition and single-fault condition.
Query Returns the allowable value setting as four-digit numeric data in NR3 format.
(unit : A)
Returns one allowable value each for normal condition and single-fault condi-
tion.
• Internally powered equipment
The allowable value of fault condition returns zero (+0.000E+00).
Example Command
:CONFigure:COMParator:DC +50.00E-06,
+100.0E-6
Sets the allowable value to use when making DC measurements for normal
condition to 500.0 mA, and the allowable value for single-fault condition to
1.000 mA.

(Headers: ON)
+50.00E-06,+100.0E-06
(Headers: OFF)
The allowable value to use when making DC measurements for normal
condition has been set to 500.0 mA, and the allowable value for single-
fault condition has been set to 1.000 mA.
Error An execution error occurs in the following cases:
• When the selected measurement mode is not
Patient auxiliary current,
Patient leakage current I, Patient leakage current (Patient - Earth), Patient
leakage current (SIP/SOP), Total patient leakage current (Patient - Earth),
Total patient leakage current (SIP/SOP)
• If the set numeric value is not within the specified range (Command)
• When a mode other than "leakage current mode" is set
• In automatic measurement (Command)
Note
• Use this command after executing the
:MODE
command to activate the
Patient auxiliary current, Patient leakage current I, Patient leakage current
(Patient - Earth), Patient leakage current (SIP/SOP), Total patient leakage
current (Patient - Earth) or Total patient leakage current (SIP/SOP) mode.
