3.4. USE OF RESET AND AUTOMATIC SELF-TEST
3.4.1. Reset
The Reset pushkey is useful for quickly terminating execution of a control function
following choice of an incorrect function or one that is not self terminating. In such
circumstances, pressing the Reset key will return the 2313 to normal standby status
where selection of a new function is possible.
Another use of the Reset pushkey is in ensuring that the 2313 always selects the
appropriate control mode following alteration of its Address Switch. In addition, it is
capable of restoring normal operation of the Recorder when this has been blocked by
a minor malfunction or mains interference.
However,
whether this use of the Reset key
is successful or not largely depends on type of disturbance. If not successful, normal
operation can usually be restored by selecting Power Off for a couple of seconds and
then selecting Power On. This has the effect of performing a power on reset, which
returns the 2313 to its initial power on status
,
deleting measurement data stored in its
volatile memory. An alternative method of performing a power on reset is as part of
Self-Test,
and is described in section 3.4.2.
Yet another means of restoring normal operation after a minor malfunction is by press-
ing the Paper Feed pushkey and whilst keeping it pressed
,
momentarily pressing Reset.
This performs a hard reset which resets the entire instrument including its built-in
clock
,
plus deletes all measurement data in its volatile and continuous memories. A
hard reset should therefore only be performed after having tried the other methods of
reset described.
If the 2313 fails to respond correctly even after a hard reset, then it is likely that a
more serious fault has occurred. To check the Recorder plus the Application Package
the Self-Test mode discussed in section 3.4.2 can be employed
.
3.4.2. Automatic Self-Test
For checking the correct function of the
2313,
it is equipped with a Self-Test
mode.
This may be activated in two
ways,
the simplest of which is by pressing the extreme
right-hand key in the second from top row of pushkeys and while keeping it depressed
,
momentarily pressing Reset. The 2313 then starts the test cycle described below and
on completion of the tests performs a power on reset which returns the 2313 to normal
power on status plus deletes measurement data stored in the volatile memory of the
instrument.
