:MEASure:MAXimum?
<numerical value 1>,<numerical value 2>,<numerical value 3>,<numerical
value 4>,<numerical value 5>,<numerical value 6>,<numerical value 7>
<numerical value 1>
= Maximum value (NR3)
<numerical value 2> = Judgement (NR1)
0 : Equal to or less than the allowable value (PASS)
1 : Greater than the allowable value (upper limit)(FAIL)
2 : Smaller than the allowable value (lower limit)(LOW)
3 : No judgment
<numerical value 3> = Power supply polarity (NR1)
(When the equipment under test is internally powered equipment,
touch current (enclosure - line). When enclosure - line leakage cur-
rent, the value is 0)
0 : Positive phase
1 : Negative phase
<numerical value 4> = Equipment under test status (NR1)
0 : Normal condition
1 : Single-fault condition
(Disconnection of one wire in power line)
2 : Single-fault condition
(
Disconnection of protective earth conductor
)
3 : Single-fault condition
(Application of 110% voltage : Positive phase)
4 : Single-fault condition
(Application of 110% voltage : Negative phase)
5 : Single-fault condition (line voltage application : L)
6 : Single-fault condition (line voltage application : N)
Syntax Response <numerical value 5> = Target current(NR1)
0 : AC+DC
1 : AC
2 : DC
3 : ACpeak
<numerical value 6> = Other 110% voltage application
0 : Application of 110% voltage : none
1 : Application of 110% voltage : Positive phase
2 : Application of 110% voltage : Negative phase
(0 for ST5541)
<numerical value 7> =
Specific 110% voltage application
0 : Application of 110% voltage : none
1 : Application of 110% voltage : Positive phase
2 : Application of 110% voltage : Negative phase
(0 for ST5541)
Function Query Returns the maximum value, the corresponding judgment, power supply polar-
ity and equipment under test status as a numeric value.
The data is arranged as follows : <1.Maximum value>, <2.Judgement>,
<3.Power supply polarity>, <4.Equipment under test status>, <5.Target cur-
rent>, <6.Other 110% voltage application>, <7.
Specific 110% voltage application
>
(unit of (1) maximum value : A)
