Event/action function
An example of setting the event/action function is given below.
Set the event/action function if you want to reset the results after computation is carried out for a
certain period of time, then resume computation.
1. Set TIMER RST for the MFUNC KEY:1 event.
2. Set MATH:START for the same MFUNC KEY:1 event.
3. Set MATH:RESET for TIMER:1 event.
4. Set the mode for TIMER No.1 to RELATIVE and TIME to “00 01:00”.
After the above settings have been made, press the MFUNC1 key. Timer 1 will be reset
according to the above steps 1 and 2, then computation starts. After elapse of one hour,
computation results will be reset according to step 3, but computation will still continue. When a
further hour elapses, computation results will be reset. The above operations will be carried out
repeatedly until computation is stopped.
For a detailed description of the event/action function, refer to 9.1, “Setting Event/Action
Functions” (page 9-1). Refer to pages 2-9, 6-2 and 6-3 for a description of timers.
Status display during computation
The following status symbols are displayed in the sub-display 2 (lowest display section).
C : Computation is in progress.
X : Incomplete measurement has occurred. If this status occurs frequently, reduce the number
of equations or reduce the measurement period. The number of equations may be too large
for computation to be carried out within the specified measurement period.
Restrictions during computation
The following settings cannot be made while computation is in progress.
• Measuring range
• Computation equation/constant
• Group
• Copying with RANGE COPY set to on
