  • Hello! I've reviewed the operating instructions for the Longacre Stopwatch SC-505. This multi-mode stopwatch features single event, lap, and split chronograph modes with timing up to 24 hours and 1/1000 second resolution. It includes a lap counter, memory recall, and on-demand memory for recording times. I am here to answer any questions you might have about using this device.
  • How can I make the display show all zeros?
    How do I select between LAP and SPLIT chronograph?
    How to time single event?
    How do I recall previous readings?

Operating Instructions
The SC-505 is a Multi-Mode Stopwatch featuring single event timing, interval (LAP)
chronograph or accumulated (SPLIT) chronograph functions. You can time events in any mode
up to 24 hours with 1/1000 second resolution. The SC-505 automatically counts up to 99 lap or
split readings and has memory recall of the last five (5) readings.
Before operating the SC-505, the display should show all zeros. If the timer is not running
(STOP appears), press “B” until all zeros appear. If the timer is running (RUN appears) press
“A” to stop and press “B” until all zeros appear. Select the lap or split chronograph by pressing
“D”. The mode selected will be indicated by LAP or SPLIT appearing in the top row.
The Lap Chronograph records and displays the interval of time from the previous reading(s).
The Split Chronograph shows the accumulated time from the start of the event.
TIMING SINGLE EVENTS: You may time single events in either the lap or split mode. Press
“A” to start timing (RUN appears). Press “A” again to stop timing (STOP appears). Press “B”
to reset to all zeros.
MULTIPLE LAP or SPLIT TIMING: Select LAP or SPLIT mode by pressing “D”. Press “A” to
start timing. RUN appears. Press “B” to record lap or split times. The LAP COUNTER will
increase by one (1) for each reading taken. Press “A” to stop timing and “B” to reset to all
zeros.
LAP RELEASE: The time reading will remain frozen for 15 seconds or press “D” to release the
chronograph to current running time.
MEMORY RECALL: You may review up to the previous five (5) time readings by pressing “C”
(RECALL appears) while the timer is running or stopped (but not reset to all zeros).
OTHER FEATURES: (1) ON DEMAND MEMORY. You may continue to record lap or split
times by pressing “B” even while you are using the RECALL function. (2) Record
CONTINUOUS SINGLE EVENTS by pressing “A” to start timing and “A” again to stop timing.
Repeat this sequence as many times as necessary. Reset to all zeros by pressing “B” while the
timer is stopped. (3) The LAP COUNTER automatically records up to 99 readings, after which
the timer will stop.
