directly in the coin-operated machine using the Teachmode Function
(see On site programming).
Yet another alternative would be to transfer a previously prepared
complete coin parameter data set from the PC to the coin selector. This is
commonly referred to as the Cloning Function. This method is far less
involved than calibration because it dispenses with the time consuming
task of inserting coins. A pre-requisite however is that an approved and
appropriate coin parameter data set is available. These may be acquired
via the internet from WH Münzprüfer (info@whberlin.de).

Under the Edit pull down menu is the function Calibration”. Pressing the
<F4> key can also directly access this window. This will bring up the
following window:
Fig. 4 Window Calibration
At the top left side a coin channel to be calibrated is selected. The coin
value and currency code for the selected channel is displayed provided
that it has been written to the file as being programmed to that channel.
This is shown next to the channel number.
Not only the coin channel may be chosen but also the calibration mode.
The calibration mode is activated for the chosen coin channel from the
data set, it may be modified at any time until the end of the calibration.
The calibration mode “fix” is intended for use with coins and coin channels
for which preset tolerance parameters are available and calibration mode
“fix” is also preset. As a general rule, “fix” provides the best results when
such information is already available.
The coin tolerances are automatically adjusted to the test coin set when
“narrow”, “average” or “broad” are chosen. This makes them particularly
appropriate for the calibration of new coins or tokens in the absence of
coin data sets.
Each of the calibration ranges approximates coin acceptance as follows:
narrow approx. 95%,
average approx. 98%,
broad approx. 99%.
