DT9100 B
7.8. Synchronisation gate time (06. menu item)
Function The setting of the pulse width of the remote
synchronisation signal. When the active state of the
synchronising pulse is lower then this value the instrument
will not accept it as a synchronisation pulse (this function is
useful for filtering a false pulse caused by noise). The
active state of the pulse is low (closed contact
R < 1 kΩ. between contacts 7 and 8 at the synchronisation
terminals).
When the pulse is in a low state the clock stops (and you
will see the

mnemonic on the display), and when
the pulse goes to a high state, the clock starts (and you will
see the time on the display).
