Biodex Atomlab 950: troubleshooting and error codes

The ServiceForge knowledge base holds 3 documented symptoms for the Biodex Atomlab 950, with 5 ranked causes, 7 diagnostic checks with test points and expected values, and 0 error codes. Each symptom below shows its causes and the first check; the rest is one connection away. Connect ServiceForge to your AI

Symptoms

Calibration: Daily system calibration radiation

System requires daily calibration before counting operations. Calibration performs automatically, measures peak height and baseline, calculates FWHM, and equates peak channel to 662 keV for Cs-137.

Ranked causes

1. System startup and stabilization requirement (common)
2. Separate calibrations needed for probe and well detectors (common)

First check

Verify system has been ON for minimum warm-up time

Test point: System power status
Expected: System ON for at least one hour

3 more checks with pass and fail actions, 2 corrective actions, and part numbers are in ServiceForge. Connect ServiceForge to your AI

Calibration: High voltage adjustment high voltage

High voltage adjustment sets detector gain and maximum measurable energy. Must be performed initially, when used in new environment, or after substantial equipment changes like tube replacement. Resets previous calibration and Chi-Square.

Ranked causes

1. Initial system setup or environmental change (occasional)
2. After calibration reset, must recalibrate detector (common)

First check

Ensure system is ON and warmed-up

Test point: System power and thermal stability
Expected: System powered and stabilized after warm-up period

Calibration prompt system message

System displays message when daily calibration is due and will not allow measurement procedures to commence until calibration prompt is answered.

Ranked causes

1. Scheduled daily calibration reminder (common)

First check

Respond to calibration needed prompt

Test point: System prompt display
Expected: Calibration needed message shown; measurement procedures blocked
