7.5 (MR) Measuring Range / Green LED
The measuring range or "stroke length" of the sensor must be set accurately to opti-
mize the interdependence of the other parameters. This value is indicated on the sen-
sor label as "stroke" and will be in either inches or millimeters.
1) Hold the programming switch in Position #2 until the 'MR' LED begins to flash (
≈
3 sec.)
ADJUST 2) Enter the measuring range using BCD switches S1 - S6.
Example:
Update Time Formula:
Tud = [(Lm + 120 mm) (13) (N)] ÷ 36
Where:
Update Time (in milliseconds) = Tud
Length in mm = Lm
Circulation Count = N
1) Hold the programming switch in Position #2 until the 'ZERO' LED begins to flash (
≈
3 sec.)
SETUP
The MK292 is now ready to accept the next parameter -- Null Adjust (ZERO).

Pin c14 of the MK292 permits you to select the unit of
measurement (i.e., inches or millimeters) and must be
wired accordingly (refer to section 4.2).
