6
Current value judgment Result of comparison of the current 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
7
Power source polarity for the
current value
Connection with the power source
Normal: , Reverse:
8
Condition of the equipment to
be measured for the current
value
Condition of the equipment to be measured
Normal condition:
Single fault condition (open power lead):
9
Allowable value Current setting of the allowable value in normal condition or single fault
condition
10
Setting display for the
equipment to be measured
The following parameters are displayed:
Setting for the class of the equipment to be measured
Model name, Number, Current consumption monitor value, Line voltage
monitor value
Key Description of the function
11
(Clear the maximum
value)
Use as necessary to clear unnecessary data and start new measurements.
As long as this key is not pressed, the maximum value is not cleared even
after changing measurement settings in the same measuring mode.
The maximum value is cleared after changing the measuring mode.
12
Opens the allowable value set-up window.
Two allowable values in normal condition and single fault condition can be set.
Range of the allowable values: 5
μ A to 20 mA
For details, refer to Section 7.6.1, "Allowable Value Setting."
13
Opens the polarity and equipment condition set-up window.
1. Select either the or mode.
For automatic measurement, refer to Section 7.6.3, "Automatic
Measurement Setting."
2. When in the manual mode, in addition to making measurements while
changing the polarity and condition of the equipment to be measured, the
maximum value data can be printed out or saved.
Power source polarity selection:
NORMAL: , REVERSE:
Condition of the equipment to be measured:
Normal condition:
Single fault condition (open power lead):
