Elapsed Time Mode
DPS3300 Series can be programmed to run as timer. In this mode the unit will
indicate elapsed time in hours, minutes and seconds. The display format is
'HH.MM.SS'. This mode is selected during SYS Setup by opting for
'ELPSD t'. The elapsed time is the time passed since the unit was turned on or
when the time was last reset. To reset the time, first push the TIME key and
while keeping it pressed, push the RESET key. The display will show
'rESEt' and on release of the RESET key, the display will reset to '00.00.00'
and begin timing.
The elapsed time can also be momentarily displayed while the unit is
operating in any other display mode. This is done by pushing the TIME key
once. The unit will first display the word 'ELPSd t' followed by the elapsed time. This will stay in the display window for
a brief period and then the unit will revert to the normal display mode.
