401-405 SERIES - 11 - Since the alarms act as switches they do not produce a voltage or current signal. However, they can be used to generate a voltage signal on an Alarm Out line. This is done by connecting a suitable pull-up resistor between an external voltage supply and the desired alarm line wh...

401-405 SERIES - 12 - 2.2. Rotary Gas Selector The Hastings 400 Series flow meters can have up to eight different calibrations stored internally. These are referred to as gas records. These records are used to select different gases, but they can also be useful in other ways; for instance reporting ...
