Adjusting the Lo-Co Voltage Offset

Step	Procedure

1	Identify the Magnetic Encoder voltage required by the cards. (Note: The
	required encoder voltage for the cards will need to be known in order to
	properly set the Encoder Voltage Offset value. This information should be
	available through the card manufacturer or reseller).

2	Use the following equation to identify the proper Mag Lo-Co Voltage Offset
	value
	• ((((36500/(((<Desired Voltage>+4.6)/1.23)-1))-2670)/39.0625) – 126)X-1
	For example:
	Required Encoder Voltage = 1.5vdc
	• ((((36500/(((1.5+4.6)/1.23)-1))-2670)/39.0625) – 126)X-1 = -42

3	Change the Mag Lo-Co Voltage Offset value.
	I.E -42

4	Use the Diagnostic Utility to run a Magnetic Self test and verify encoded
	quality.
