F 38 CHANGE OF ANGULAR READING MODE
On request, the instrument may be configured with one or more Axes operating in angular
reading mode. The Axes concerned are linked to rotating encoders and a letter A is shown
on the first digit of the display.
The resolution depends on the number of pulses of the encoder used (PPR).
The instrument, which knows the parameters, performs the exact calculation of the
following formula:
360° and chooses, among the available resolutions, the one which is closest
PPR x 4 to the calculated value
AVAILABLE 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°), which can be obtained
using an encoder having a PPR of 90.000.
Angular reading mode can be selected by the operator:
A) Angle from 0° to 360°
B) Angle from 0° to 180° in the
POSITIVE FIELD
and from -180° to 0° in the
NEGATIVE FIELD
To switch from one type of reading to another, the operator must proceed as follows:

NOTES: 1. The selection made will be stored permanently.
2. Not all the functions proper to the Axes can be performed in linear
reading mode, that means:
MMS/INCHES - CONSTANT PITCH - ALGEBRAIC SUM -
LINEAR CORRECTION - SCALE FACTOR -
RADIUS/DIAMETER CONVERSION
3. All the other functions described in this manual are available.
4. The instrument will never enter into a state of “overflow” error, because the
counting is reset after each full rotation (or half-rotation).
