Page 14: Calibration Of The Am-5150
Span function sets the sensitivity of the instrument. Initial Calibration: Wait at least 3 – 4 hours after initially supplying power to the AM-5150 instrument before initial calibration, overnight is preferred. The AM-5150 has been pre-calibrated at the factory, and initial field calibration should result in only fine-tuning to circuit, as well as a way to check that installation is successful. -
Page 15: Exit Maintenance Menu
Maintenance Menus 5.2.2 Zero Adjust The ZERO function must be performed by exposing the AM-5150 instrument to clean fresh air. If the air at the sensor is in question, use a cylinder of 20.9% oxygen to provide a clean air reference. -

Software revision may cause variations of display output. 5.2.5 mA Span Set The AM-5150 4-20mA span range is set at the factory, normally to the full scale of the measurement and can be changed within limits. To change the span range: Enter the maintenance menu as shown in Figure 7 AM-5150 Maintenance Menu flow chart. -
Page 18: Sensor Replacement
ROCEDURE ARNING Power must be removed from the AM-5150 before this or any internal procedure. Failure to do so may cause damage to equipment, bodily injury or death. 1. Obtain a new sensor assembly. Make sure the sensor type is identical to your original sensor Sensor marking is on side of sensor see Figure 9 (Example: 813-4 the first 3 digits are sensor ID the 4 digit indicates a 4-wire sensor). -
