Scale Basic 4.2E Reference
Timer Events
Purpose 1: to trigger a scale basic function after a set time interval.
Purpose 2: to wait an interval of time inside a scale basic function.
Remarks: Timers are activated using the Scale Basic instruction: Timer on [t]. When a timer is
activated, the time interval is set into the timers countdown register. The countdown register
decrements by 1 every 0.1 seconds. When the countdown reaches 0 the Scale Basic function
is executed. There are 5 timer records that contain the following data:
Time interval [P0]
time interval in tenths of a second (x0.1sec). Max = 6553.0 sec.
Execute Function[P1] the scale basic function to execute when time-out occurs.
Timers 1-4 must be reactivated with a Timer on instruction to begin again. Timer 5 is an
auto-reload timer.
Timer5: automatically reloads after it counts down to 0. This provides more accurate timing of
repetitive events (such as pulse outputs, speed calculations, interval timing, etc.). Timer5
continues cycling until the Timer off, 5 instruction is executed.
Example Purpose 1: trigger user function 7 after a 1 minute time-out. Configure timer 1:
Time interval 600 1 minute = 60.0 seconds
Execute Function User7 execute user function 6
Example Purpose 2: display a message for 2 seconds then display Gross weight. Configure
timer 1:
Time interval 20 set for 2.0 seconds
Execute Function User1 execute user function 1
Fn. 1 Prompt, ERROR
Display ‘ERROR
Timer on, 1 turn on timer 1

If Timer1 Timer 1 is on
Next1 Wait
End if End While
Display, Gross Display Gross weight
Example Timer5: Pulse relay output 1 at 0.2 second intervals.
Configure F1 key to execute user function 10.
Configure Timer5 to execute function 10 after a 0.2 second time-out.
Time interval 2 set for 0.2 seconds
Execute Function User10 execute user function 10
