1. Each current can be shown in 3 ways: an histogram, a value and a percentage; all calculated with
the same accuracy rule:
VALUE has no more than 6 spaces. If VALUE ≤ 9999 is shown on 4 digits plus the symbol “A”,
using so 5 spaces. If instead 9999 < VALUE < 99999 digits are only 3 with a decimal digit divided
by a dot and followed by “k” and “A” symbols (so 6 spaces) and are obtained reducing VALUE
to the nearest lower decimal (Example: 12550 A become 12500 and is shown as 12.5kA). If is
VALUE≥99999 digits are still 3, but are hundred, decine and unit, obtained once more reducing
to the nearest lower unit and followed by the symbols “k” and “A” (so 5 spaces). (Example:
245650 A become 246000 and is shown like 246kA).
If PERCENTAGE > 999% is shown the symbol > > > %.
2. Histograms of currents can shown values among 0 and 1,2*I threshold [A], where I threshold
is the threshold current for thermal protection (Ir); if detected current is higher than maximum
value, the histogram is shown complete (so equivalent to a threshold of 120%).

3. Temperature is shown in 3 ways: an histogram, a value and a percentage; all calculated with
the same accuracy rule. VALUE has no more than 5 spaces, 3 digits (only integer values) and the
symbol “°C”. If PERCENTAGE > 999% is shown the symbol > > > %.
4. Temperature histogram shows values among 0 and 95 [°C]; if detected temperature is higher than
maximum value histogram is shown complete (so equivalent to 95°C).
5. Residual charge on battery is shown in 3 ways: an histogram, a value and a percentage; all calcu-
lated with the same accuracy rule. VALUE has no more than 5 spaces, 3 digits (decine, unit and
1 decimal digit separated by a dot) and the symbol “V”.
6. Histogram of residual charge on battery shows values among 0 and 12 [V]; if detected battery is
higher than maximum value histogram is shown complete (so equivalent to 12V). Additionally,
for
absolute values
of voltage ≤ Val. Min. Batt. (settable parameter, see Main page – System
options), is shown an empty histogram and the message “Change battery” instead of the per-
centage value.
