Analogue outputs are an optional extra that must be ordered for installation during
manufacture; they cannot be retrofitted to the gauge.
The analogue outputs may be configured to output diameter or error measurements as an analogue
output voltage.
Analogue outputs connection
Three analogue outputs may be accessed through the “INTERFACE” connector.
Connector type: DB25 female (socket)
