• uses a special calibration utility program (DHM).
GS recalibration should be performed:
• annually.
• whenever a 6510 Signal Input module is replaced.
• whenever a 6560 Processor module is replaced.
• if the calibration table has a status of "Unknown".
Product Support personnel can guide a plant engineer or technician through GS calibration
over the phone.
B.1.4 Digital Signal Processor (DSP) calibration
Digital Signal Processor (DSP) calibration:
• uses a CPU board's TSG output signal.
• does not require that any wire harnesses be disconnected.
• is completed in about 30-40 minutes.
• does not require any special cables or test equipment.
• uses a special calibration utility program (DHM).

B.1.5 Transient calibration
The Transient unit includes two processing boards—a Main Processor board and a
Transient board. Both boards include separate Digital Signal Processors. The DSP on the
Transient board uses an internal calibration table, in much the same way that the Main
Processor DSP circuit does. However, it is calibrated separately, and not as part of a DSP
calibration for a Main Processor.
Transient calibration:
• uses a Processor module's TSG output signal.
• does not require that any wire harnesses be disconnected.
• is completed in about 30-40 minutes.
• does not require any special cables or test equipment.
• uses a special calibration utility program (DHM).
