When fitting an EASSON scale always set to 0
Suppliers-Easson, Mitutoyo, Futaba Suppliers-Fagor
REF SIGN = 0 REF SIGN = 1
Normal Voltage = 0V Normal Voltage = 5V
At ref point = 5V At ref point = 0V
Press the UP/DOWN keys until the word "REF SIGH" is shown in the MEASSAGE WINDOW,
Press the ENTER key to access the next menu level. Press the DOWN key once and the

In the market there are many gratings using a 20μm pitch. There are two types of
electronic signal which generate the reference point. The first associates the signal
with a rise in voltage, the second with a drop.

5.) Press key to make your setting, then press key to select the "LIN COMP"
(linear compensation) function.
Press key into the linear error compensation function, the formula as below：
error value X -(1000/measuring length) = compensation value
(ML) measuring length unit = mm, error unit = μm
Example：
ML=500mm Error = -15μm
-15μ X -(1000/500) = 30μm
the compensation value is 30μm
If set up the linear compensation value of X Axis = 30, through the AXIS key make a
same procedure for Y Axis.
6.) Press key to make youn setting, then press key to select the "REF SIGN"
function.
