7. Pulse Generators
TypeIN-SxxorIN-WLF pulse generators may be plugged
onto the side of the index cover for volume pulse output to
external devices (e.g. a volume corrector).
Fitthepulsegenerator(ifrequired)asfollows:
– Slide both guidesoftheIN-Spulsegeneratorintothe
guide slot on the index cover until the guides can be
heardtoengage(clickingsound).
– Assign the terminalsonthepluginaccordancewith
the pin assignment on the meter/pulse generator.
– Use a screened cable to the external device.
You can use HF pulse generators (Types A1R and A1S)
forhigherfrequencies(ifavailable).HFpulsegeneratorsare
screwedintothemeterhousingpressure-tight.However,the
connection plug can be turned.
