CONTROLS/INDICATORS
ON/OFF
button turns unit on and off.
FORMAT/(ALM
“
)
button permits timing in four different formats:
decimal seconds, decimal minutes, decimal hours and clock.
Illuminated LED indicates the current timing format. During alarm
operation, FORMAT/(ALM
“
) button allows user to advance digits.
DISPLAY/(ALARM)
button allows user to view the running time of the
internal clock while unit is in Cumulative or Interval Timing mode.
During alarm operation, DISPLAY/(ALARM) button permits setting,
changing and deleting an alarm.
MODE/(ALM
Ž
)
button permits timing in four different modes: start/
stop, cumulative, interval, and time-out. Illuminated LED indicates
the current timing mode. During alarm operation, MODE/(ALM
Ž
)
button allows user to select each digit on display for individual digit
advancement.
RESET
button resets the internal clock and display to zero.
START/STOP
button permits starting and stopping timing opera-
tions, performs time-outs and resets display to zero, depending on
current mode and number of times pressed.
TIMING OPERATION
Single action timing
In Single Action Timing mode, unit times uninterrupted single events.
1. Press MODE/(ALM
Ž
) button until START/STOP light illuminates.
2. Press FORMAT/(ALM
“
) button until desired format light
illuminates.
3. If display is not at zero, press RESET button to return display
to zero.
4. Press START/STOP button to begin timing.
5. Press START/STOP button a second time to stop clock for a
readout.
6. Press START/STOP button a third time to automatically reset the
internal clock and return the display to zero. This action also
restarts clock.
Cumulative Timing
In Cumulative Timing mode, unit records any number of cumulative
timing breaks while internal clock continues.
NOTE:
Blinking digits on display indicate the internal clock continues.
1. Press MODE/(ALM
Ž
) button until CUMULATIVE light illuminates.
2. Press FORMAT/(ALM
“
) button until desired format light
illuminates.
3. If display is not at zero, press RESET button to return display
to zero.
4. Press START/STOP button to begin timing.
5. Press START/STOP button a second time to “freeze” display for
recording a time while the internal clock continues to run.
6. Successive presses of START/STOP button “freezes” and shows
the accumulated time from the original start while the internal
clock continues to run.
7. Press DISPLAY/(ALARM) button to “unfreeze” display and show
the cumulative running time.
Interval Timing
In Interval Timing mode, unit records any number of noncumulative
timing breaks.
1. Press MODE/(ALM
Ž
) button until INTERVAL light illuminates.
2. Press FORMAT/(ALM
“
) button until desired format light
illuminates.
3. If display is not at zero, press RESET button to return display
to zero.
4. Press START/STOP button to begin timing.
5. Press START/STOP button a second time to “freeze” display while
the internal clock automatically resets to zero and begins timing.
6. Successive presses of START/STOP button “freezes” the display
and shows the elapsed time since the previous press.
7. Press DISPLAY/(ALARM) button to “unfreeze” display and show
the interval running time.
Time-Outs
In Time-out mode, unit permits any number of stops to be performed.
Unit stops and restarts internal clock upon user command. Total
cumulative time will not include time-outs.
1. Press MODE/(ALM
Ž
) button until TIME OUT light illuminates.
2. Press FORMAT/(ALM
“
) button until desired format light illuminates.
3. If display is not at zero, press RESET button to return display to
zero.
4. Press START/STOP button to begin timing.
5. Press START/STOP button again to stop timing for a time-out
(both internal clock and display will be halted).
6. Press START/STOP button a third time to resume timing from the
point at which it was stopped.
Simultaneous Timing
Up to 12 events may be timed using any combination of the available
timing modes (start/stop, cumulative, interval, time-out) and timing
formats (decimal seconds, decimal minutes, decimal hours, clock). To
view the status of any timed event, simply use MODE/(ALM
Ž
) and
FORMAT/(ALM
“
) buttons to enter appropriate timing mode and
format.
WARNING:
When an attempt is made to set more than 12 different
event times or more than 4 alarms, unit emits a signal and the display
will not respond to the keyboard.
Continuous Timing
For events lasting longer than the unit’s maximum timing capacity, unit
instantly rolls over to zero and continues timing.
