A series of numbers. the indicator is gas-discharge.
Recommendations for use:
Working position — any.
Cooling is natural.
When installing the indicator on printed circuit boards, bending of the pins is allowed.
Fastening by pins is not allowed.
The indicator is connected to the control circuit through tinned contact petals by soldering
tin-lead solder.
The indicator must be operated in multiplex mode.
Digital multi-digit gas discharge indicator IGP-17 is designed for
to display information in the form of digits from 0 to 9 (and decimal places) in
each of the 16 digital digits and additional information in the service
the category in the media of displaying information for individual and group use.
The case is flat, glass. Weight not more than 150 g.
