IMPORTANT
• The instrument may be unable to properly detect
overload states immediately after the current range has
changed.
• The currents for which an overload state can be detected
are DC and sine waves with frequencies of 45 Hz to
66 Hz. The device is unable to detect the currents listed
below as an overload state.
- Currents that exceed the defined level on a
momentary basis
- High-frequency currents that exceed the defined level
Measuring Currents
4
Check the LEDs on the junction box.
The
POWER
LED
and one of
the
RANGE
LEDs light up.
There is no error.
Go on to step
5
.
The
OVERLOAD
LED blinks rapidly.
The device has detected a measurement current in excess
of the level defined for the current range.
See “Overload” (p. 90).
When you use the 30 A range
Immediately remove the sensor from the conductor
under measurement.
When you use the 0.5 A range or 5 A range
Switch a higher current range.
Any other LEDs lights up or blinks.
A different error is occurring.
See “4.2 Errors” (p. 88) to identify a reason and take
necessary measures.
