Wharton day-date calendar wall clocks have many user-selected modes of operation:

  • E and NE versions can be used in stand-alone applications using their internal time references.
  • The clock has rear connections to enable time synchronisation using one of a wide selection of time code protocols from a Wharton 5000 series master clock or suitable third party time reference.
  • You can synchronise individual calendar clocks with a satellite-based atomic time reference via a control message from a Wharton 488HS series GPS or GLONASS time signal receiver.
  • N and NE versions can be controlled and synchronised to time via their 10/100Base-t Ethernet NTP connection to your existing network with accurate time information provided by a local or internet time server for simple, low-cost installation and control.

Stopwatch operation

  • Wharton 4000 series time and date clocks have time digits freely switchable between the display of time-of-day and multifunction stopwatch or countdown time.
  • The standard RC100 IR handset controls the stopwatch and countdown timer functions.
  • You can also control the stopwatch functions of E and NE versions with an optional 496E dedicated switch panel or by external user-supplied voltage free contacts.
  • Multiple N or NE versions of 4000 series clocks may be operated in Network Stopwatch Mode to provide a remote readout of stopwatch or timer counts.
