In the standard specifi cations, the minimum phase diff erence is fi xed at 50 ns for the
DK800SA and 100 ns for the DK800SB, but the minimum phase diff erences in the table
below are available as custom specifi cations.

If the response speed is exceeded, the AB quadrature signal output from this
measuring unit changes to Hi impedance for about 400 ms to serve as an alarm.

When e x tending the cable ( Magnescale-approved cables only ) , e x tend so that the supply
voltage is +5 V ±5% at the e x tension target.
Use the C E22 series e x tension cables for bare wires ( optional accessories ) .
