*1:
When the
JA
W UNLOCKED
LED is lit up or the
OVERLOAD
LED is fl
ashing, the
DEMAG/AUT
O ZERO
LED will not be
lit, even before demagnetization and zero-adjustment.
*2:
When the
DEMAG/AUT
O ZERO
key is pressed while the
JA
W UNLOCKED
LED is lit up or the
OVERLOAD
LED is
fl ashing, or while a current value of 0.5
A rms or greater has been detecting.
(Demagnetization and zero-adjustment are disabled.)
*3:
When an internal temperature anomaly is detected. (Pressing the
DEMAG/AUT
O ZERO
key after removing the device
from the target conductor and waiting for it to cool of
f will return the device to its normal state after starting up.)
*4:
CPU malfunction (Checksum error). (Have the device repaired.)
*5:
Greater than prescribed level 1 (Rating warning):
Approx. 4.75
A rms (DC, 45 to 66 Hz sine wave)
Greater than prescribed level 2 (Rating exceeded):
Approx. 5.25
A rms (DC, 45 to 66 Hz sine wave)
