Error Codes
When the N
-
560 detects a defective sensor connected to the N-560, the N-560
displays an error code of “SEN Err.” The sensor should be replaced and the
N-560 power should be cycled.
An error code is displayed when the N-560 detects a non-correctable failure.
Cycling the power clears these errors. Table 11 lists the N-560 error codes
and their meanings. When one of these errors occur, the N-560:
• sounds a low priority alarm that cannot be silenced except by
power-down
• stops measurements
