​

AMX service mode, calibration mode, extended diagnostics
Question

What is AMX-Series service mode used for?

Short Answer

Service mode is intended for service personnel and provides access to calibration, extended diagnostics, data logs, and data-base access.

Possible Causes

Service/maintenance task.

Troubleshooting Steps

Use the service switch and approved service procedure. Restrict calibration and data-base changes to qualified personnel because incorrect values can affect system operation and exposure output.

Error Number

Oscilloscope triggering during calibration

Error Code System Message

​

AMX oscilloscope trigger calibration, CALIBRATE KVP
Question

How should I trigger an oscilloscope for AMX-Series generator calibration?

Short Answer

The manual recommends establishing the scope trigger before entering CALIBRATE KVP because the unit fails power-up tests in calibration mode.

Possible Causes

Difficult oscilloscope triggering during service calibration.

Troubleshooting Steps

Set up the trigger in normal operating mode using the specified low-kVp/mAs test exposure, then enter calibration with the scope already triggering reliably.

Parts Areas to Check

Generator calibration test points
