Operation 9
Switch Action Display Comments
Press 2 " 2 " 345 Pressing the key will change digit and
enables the next digit to be
incremented.
(The right arrow on the RUN key indicates
to change digit.)
Press PRESET 22345 Pressing PRESET returns the instrument
to the Run mode and batches can now be
run.
Note: If there are no keys pressed within 10 seconds while the instrument is
in preset mode it will return to the run mode saving the current value as the
preset quantity.
Upon exit of preset mode the value is checked against the programmable
batch limit. If the value is greater than the batch limit the preset value is
set to the programmed limit. This check is disabled if the batch limit is
programmed as zero.
Once programmed, the Preset quantity will be retained in memory and will
not alter until changed by the user. The Preset quantity can only be set
while the instrument is in a non-operational state such as when the batch
is complete, or has been cancelled.
STARTING A BATCH
To start a batch press the RUN key. The Total will then reset to zero and,
provided there is flow, the Total display will start counting upwards.
The batcher has two output transistors and these are switched on and
off as described in section 3.3.
STOPPING
The process can be stopped at any time by pressing the STOP switch. This
is indicated by the "Pause" message being displayed on the screen. Once
the process has been interrupted in this way, it can be continued by
pressing the RUN key or the process can be aborted by pressing the STOP
switch a second time.
