Troubleshooting: Diagnostic Control Screen

Recorder Calibration Test

This test provides a method of testing the recorder calibration alignments.

1. Use the Trim Knob control to set the recorder calibration field on the Diagnostic

Control service mode screen to On. The recorder prints four continuous

horizontal lines at 0 mmHg, 30 bpm, and 240 bpm and the minimum and

maximum rates on the HR scale (30 bpm and 240 bpm for domestic paper, 50

bpm and 210 bpm for international paper). The recorder prints a vertical line

spanning across both grids every 3/16 inch. Refer to figure below.

2. Use this test while performing the adjustments in “Recorder Servicing” on

page 5-7. The test will continue to print the lines until you cycle power on the

monitor or set the calibration field on the Diagnostic Control screen back to Off.
