Depending on the type of error or alarm and of the chosen resolution, the histogram scale is
linear or logarithmic. The maximum number of errors or alarms that can be shown in a histogram is
65534, but most counters can count more than that.
The histogram has two limitations: the total monitoring time and the quantity of errors that it
can store. The histogram memory is limited to up to 3663 positions. This means that if the chosen
resolution is minutes, the equipment can monitor a test during up to 61 hours. But also, the
maximum number of errored minutes that can be shown is 70. So, for example, if more than 70
minutes are monitored and they all have error(s), no more errored minutes can be stored.
