20
p is an integer that defines the time-out code, in the range 0

5
Note: This command applies only to IMP types 1H, 1J and 2A.
Function: For a specific channel, sets the time-out period for period measurements. The settings
available are listed in Table 1.17. The default period is 2 seconds (p = 1)
The time-out period is the maximum time any period or ‘one-shot’ measurement is allowed to
take. If the period to be measured exceeds this time, the error ‘period time-out’ is returned
instead of a result. For single period measurement of cyclic signals, the time-out period must
be at least twice that of the measured signal. This ensures both edges of the signal are
within the time-out period.
Response: None

≤
20
Note: This command applies only to the digital IMP (type 2A) and the Universal IMP (types 1H and 1J).
Function: Instructs the IMP to clear its’ event totalise counter and to inhibit counting until the next ME or
TR command, for a specified channel only. The event totalise counter keeps a continuously
updated record of the number of events that have occurred since an initial ME or TR
command. It can only be cleared by a power-down or the CL command. Maximum count
value = 16,777,215.
Response: None.
