Batch Number
To set the Batch number, use the right-hand button (arrow up) to step through the digits sequentially.
The left-hand button (arrow left) moves the display one decade. Each decade's value may be set
using the right-hand button. When in operation, the instrument will count, and when it reaches the
number set as Batch, it will operate the associated relay.
Decimal Point
When the batch number has been set, continue to press the left-hand button to step one decade at a
time to the left. When the most significant decade is flashing, press the left-hand button again, and
the decimal point will become active. Pressing the right-hand button causes the decimal point to step
one decade to the left.
Pre-Batch
Once the Batch has been set, pressing the RESET (lower middle button) will cause the instrument to
step to the next function — Pre-Batch. Set the required value in the same way as for the Batch
Number. The Pre-Batch value is set as the value before Batch at which the Pre-Batch relay is
required to operate.
For example, in count up mode, if Batch = 1000 and Pre-Batch = 200, then the count will start at 0
and the Pre-Batch relay will operate at 800. If count down mode is selected then the count would
start at 1000 and the Pre-Batch relay would operate at 200. The Batch relay operates at 0.
This gives the advantage that if the Batch number needs to be reset then Pre-Batch value will
automatically follow and remain 200 below the new Batch number.
Scaling Factor
Pressing RESET again now allows the scaling factor to be set. As described in Calculating a Scaling
Factor above, this is be used to turn the input count in pulses into a meaningful readout. Use the left-
hand button to step to the most significant digit, press the left-hand button again, and the decimal
point is displayed. Use the right-hand button to step the decimal point to the required position.
Once a scaling factor has been set it is retained in memory upon power down. When power is
reinstated the unit will immediately be ready for operation without need for a reset command.
Count Up / Down
The next item to be set is the Count Up / Count Down option. When CNT UP is displayed, the
instrument will count up activating the relays at counts determined by the Batch / Pre-Batch settings.
Pressing the right-hand button will change the option to CNT DN. If this is selected, the instrument
will count down from the Batch setting activating the associated relay when it reaches zero. In either
case, the Pre-Batch number is an amount before the complete batch is reached.
Pressing RESET once again brings the available function back to BATCH. You can step through the
functions as many times as necessary to input or check the required settings. Once you are satisfied
that the settings are correct, pressing and releasing the BATCH SET button takes the instrument into
operating mode ready for use.
