This setting allows the user to program the DP1200 with a rotary encoder resolution.
Rotary encoder resolutions are usually expressed as 

Pulses Per Turn

. This is the number of pulses

output per revolution.
Information on the 

PPT

can be found in the encoder manufacturer’s specification and is also generally

marked on the encoder.

Please refer to Page 16, Reference Source Setup

Rotate rotary encoder until a value
is displayed in the LCD 
display. 

For this example an 1800 pulse
encoder is connected. 

PPT = Counts per Revolution (CPR) /4
