Sets and queries the allowable value(upper limit)
(when making AC measurements)(only ST5540)
Syntax
Command
Query
Response
:CONFigure:COMParator:AC
<numerical value 1>,<numerical value 2>
:CONFigure:COMParator:AC?
<numerical value 1>,<numerical value 2>
<numerical value 1> = allowable value data (NR3) for normal condition
(Upper limit, when AC is selected)
<numerical value 2>= allowable value data (NR3) for fault condition
(Upper limit, when AC is selected)
Function
Command Sets the allowable value to use when making AC measurements.(upper limit)
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.(upper
limit)
The range of numeric values is from 5.000E-06 to 50.00E-03 (unit : A)
Sets one allowable value each for normal condition and single-fault condi-
tion.(upper limit)
The allowable value for a fault condition (upper limit) for equipment with an
internal power supply is zero (+0.000E+00).
Query The allowable value (upper limit) for AC measurements is returned as a 4-digit
NR3 format numeric value. (Unit : A)
Returns one allowable value each for normal condition and single-fault condi-
tion
.(upper limit)
• Internally powered equipment
The allowable value of fault condition returns zero (+0.000E+00).(upper limit)
Example
Command
:CONFigure:COMParator:AC +50.00E-06,
+100.0E-6
Sets the allowable value to use when making AC measurements for normal
condition to 500.0 mA, and the allowable value for single-fault condition to
1.000 mA.
Query
Response
:CONFigure:COMParator:AC?
:CONFIGURE:COMPARATOR:AC +50.0E-06,
+100.0E-6 (Headers: ON)
+50.00E-06,+100.0E-06 (Headers : OFF)
The allowable value to use when making AC 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), Total patient leakage current(SIP/SOP)mode.
