NOTES:
[1] Active only during calibration mode
[2] Current will fluctuate at frequencies below 5 Hz.
[3] Factory Set
[4] Reference PCB Drawing 37476 for installation requirements
[5] Reset can also be engaged via external connection to common
[6] See PCB Declaration of Conformance PS051 for details.
[7] To obtain 60000 cpm (1000 Hz) frequency response, grease must be applied to all mechanical couplings. Otherwise, frequency response is limited to approximately 30000 cpm (500 Hz)
