<numerical value 1>,<numerical value 2>
<numerical value 1> = allowable valuedata (NR3)
for normal condition
(upper limit)
<numerical value 2> = allowable value data (NR3) for fault condition
(upper limit)
Function
Command Sets the allowable value.(upper limit)
The allowable value (upper allowable limit) of the instrument is value x (times)
coefficient and with the interface command, the coefficient is set as 100%.
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 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.
With patient leakage current I, patient auxiliary current, patient leakage current:
patient - earth, patient leakage current: SIP/SOP, total patient leakage current:
patient - earth, total patient leakage current: SIP/SOP, the allowable value for
normal condition (upper limit) is set to the allowable value for normal condition
(upper limit value during DC measurement) and the allowable value of normal
condition (upper limit value during AC measurement) and the allowable value of
a single fault condition (upper limit value) is set to the allowable value of a sin-
gle fault condition (upper limit value during DC measurement) and the allowable
value of a single fault condition (upper limit value during AC measurement).
Zero (+0.000E+00) is set, when a either value cannot be set.
The number of allowable values that can be set depends on grounding class,
network and leakage current mode. For details, refer to (p. 180). Since allow-
able values cannot be set for items indicated as "0" in the table, zero
(+0.000E+00) is set.
• When network A, D, E, or F is selected
Earth leakage current, Enclosure - Earth leakage current, Enclosure - Enclo-
sure current, Free current (only network A):
Sets one allowable value each for normal condition and single-fault condi-
tion.
Enclosure - Line leakage current:
Sets the allowable value for normal condition to zero (+0.000E+00).
Enclosure - Earth leakage current, Enclosure - Enclosure current
(Internally powered equipment):
Sets the allowable value for fault condition to zero (+0.000E+00).
• When network B1 is selected(only ST5540)
Earth leakage current, Enclosure - Earth leakage current, Enclosure - Enclo-
sure current, Free current:
Sets one allowable value each for normal condition and single-fault condi-
tion.
Patient leakage current I, Patient auxiliary current:
When testing normal and single fault conditions, sets two allowable values to
use when making DC and AC measurements.
Patient leakage current II, Patient leakage current III:
Sets the allowable value for normal condition to zero (+0.000E+00).
Patient leakage current I, Patient auxiliary current
(Internally powered equipment):
Sets the allowable value for fault condition to zero (+0.000E+00).
