Main technical features:
Display:
LCD, 8 decades, height of the figures 8 mm.
Display range:
-9999999 ... 99999999
with leading zeros suppression.
Overflow:
In case of a display range overflow, the
counter starts again from 0, but without
removing the leading zeros and activating
all decimal points.
In case of a display range underflow, the
counter starts again from 0 and displays
the minus sign, without removing the lead-
ing zeros and activating all decimal points.
