Parameter Explanation
1
Maximum value The maximum measured value obtained in the current measuring mode
Changing the measuring mode will clear this value.
In cases where the measurement current is DC, and a minus value is
measured,
is displayed.
(When this value is 1
μ
A or lower, "UNDER 1
μ
A" is displayed.)
2
Maximum value judgment Result of comparison of the maximum value with the allowable value
(In cases where the measurement current is DC, an absolute value.)
PASS
: Allowable value or lower
F A I L
: Higher than the allowable value
3
Power source polarity for the
maximum value
Connection with the power source
Normal: , Reverse:
4
Condition of the equipment to
be measured for the
maximum value
Condition of the equipment to be measured
Normal operation:
Single fault condition (open power lead):
5
Current value Value obtained from the current measurement
In cases where the measurement current is DC, and a minus value is
measured,
is displayed.
(When this value is 1
μ
A or lower, "UNDER 1
μ
A" is displayed.)
Measurement of earth leakage current is made on the earth leakage current
measurement screen.
The current measured value, maximum value, and setting condition are shown
on the earth leakage current measurement screen.
Further, windows for changing the measurement settings can be opened from
this screen.
