Troubleshooting and Error Codes
Displaying Error Codes with the Probe Degauss Autobalance Button
This section describes the error codes that the ampli fi ers display using the
function indicator LEDs.
When an internal error condition exists, the ampli fi ers may generate error codes.
To display the error codes, do the following. (See Figure 25.)
1. Press the PROBE DEGAUSS AUTOBALANCE button.
2. The AC and DC Coupling LEDs will fl ash alternately to indicate that error
codes are being displayed instead of normal conditions.
3. The four fault indicator LEDs above the ON/STANDBY switch are used to
form a four-bit binary error code. (See Figure 26 on page 44.) The error codes
are de
fi ned in the table. (See Table 6 on page 44.)
The PROBE OPEN LED indicates the most signi fi cant bit (MSB), and the
NONCOMPATIBLE PROBE TYPE LED indicates the least signi fi cant bit
(LSB).
4. To continue past an error code, press any button except ON/STANDBY.
However, the degauss will fail until the internal error condition is corrected
and the degauss operation is run again.
