On request, the instrument can be configured by the Manufacturer to operate in angular
reading, in order to be used with a rotary encoder. The resolution depends on the number
of encoder pulses (PPR).
The instrument calculates exactly the following formula:
360°
and selects, among the available resolutions, the one closest to the
PPR
x
4
calculated
value.
POSSIBLE RESOLUTIONS:
1° - 0.5° - 0.2° - 0.1° - 0.05° - 0.02° - 0.01° -
0.005° - 0.002° - 0.001°
The highest possible resolution is 3.6 seconds of an arc (0.001°), that can be obtained with
an encoder having 90,000 PPR.
If the instrument has been configured by the Manufacturer in angular reading, the operator
can select the reading mode:
A)
ANGLE from 0° to 360°.
B)
ANGLE from 0° to 180° in positive field and from -180° to 0° in negative field.
To switch from one reading mode to the other,
Press
3 8
0 - 3 6 0
Press
to select
0 - 1 8 0
Press
to confirm the selection.
1.
The selection is stored permanently.
2.
All the functions linked to the linear reading cannot be executed, e.g.:
MM/INCH - LINEAR CORRECTION
3.
The instrument will never incur into an “overflow” error because counting is reset
after each rotation (or half-rotation) of the encoder.
