3.1 External Control Inputs
Attention
!
Terminals 8, 9, 10 and 11 are electrically connected to the measure-
ment input. External switching elements must be electrically isolated
from earth as required by measurement input potential.
Reset and Device Test
The entire display is darkened if
a connection is established
between terminals 8 and 11.
Attention
: This connection
causes resetting of the
microprocessor.
A segment test is performed for
approx. 1 second after this connection has been interrupted. The instrument
returns to normal operation after the segment test has been completed.
Save Display Value to Memory (Hold)
The currently displayed value is saved to memory if a connection is estab-
lished between terminals 9 and 11 during normal display operation. This has
no effect on the measuring cycle.
Program Protection (Lock)
Selected parameters are protected against possible change if a connection is
established between terminals 10 and 11.
