AUTORANGING OPERATION
When SW1/1 on the micro board (see Appendix A Fig 1) is set on
the operation of the changes as follows:
1.
All enamel rating currents up to 45mA are displayed and
saved to two decimal places (10
μ
A). Note that 5mA of
hysteresis is incorporated in the design, so that with a
decreasing current the does not operate to two
decimal places until the current drops below 40mA.
Currents above the thresholds continue to be displayed to
one decimal place (100
μ
A).

LINE NUMBER ENABLE
When SW1/2 on the micro board (see Appendix A Fig 1) is set on
the operation of the changes as follows:
1.
On power up the prompts for a line number.
This can be set to any value between 0 and 99 using the
↑
and
↓
keys. One or more cans can then be enamel
rated as a batch. When the data is sent to a printer or
host computer the line number is also sent.
2.
When a batch of measurements have been taken and
statistical information, a printout or data transfer
completed, pressing END will cause the to
prompt for a new line number. Note that once a new line
number is entered, all data from a previous line is erased.
The line number facility is provided primarily so that a
complete set of data can be sent to a printer or host
computer.
