Troubleshooting and Error Codes

Displaying Er

ror Codes with the Probe Degauss Autobalance Button

This section describes the err or codes that the ampliﬁers d isplay using the

function indicator LEDs.

When an internal error condition e xists, the ampliﬁers may generate error codes.

To display the error codes, do the following. (See Figure 26.)

1. Press the PROBE DEGAUSS AUTOBALANCE button.

2. The AC and DC Coupling LEDs will ﬂash alternately to indica t e 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 27 on page 46.) The error codes

are deﬁned in the table. (See Table 7 on page 46.)

The PROBE OPEN LED indicates the most signiﬁcant bit (MSB), and the

NONCOMPATIBLE PROBE TYPE LED indicates the least signiﬁcant bit

(LSB).

4. To continue past an e rror code , press any button except ON/STANDBY.

Howev

er, the degauss will fail until the internal error condition is c orrected

and the degauss operation is run again.
