Hexagon TT80 - Measured Value Classification; LED and Contact Relay Classification

8 CLASSIFICATION OF THE MEASURED VALUES (disabled for TT90-UPC)
With the instrument switch to the tolerance mode, the classification of the measured val-
ues through LEDs and contact relays is enabled.
Good green LED
Scrap red LED
Rework amber LED
Internal measuring External measuring
lower Tol. ≤ Measurement ≤ upper Tol. green LED green LED
Measurement > upper Tol. red LED amber LED
Measurement < lower Tol. amber LED red LED
MEASURE mode
The LEDs and the contact relays match displayed function.
HOLD mode
Display shows the measured value. The relays are open, the LEDS are
off and the synchronous output is disabled. The commutation to their
respective state occurs with the release of the key. Displayed value will
then be sent to the RS232 digital output.

To allow for the connection of the various programmable devices either to the Vcc (internal
or external powering) or GND, the value classification with Good, Rework or Scrap uses
contact relays.
