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.

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.

8.1 Block diagram of the classification output through contact relays
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.
