3.3.5 Connecting Injection Trigger Signals

The 2410 refractometer accepts the following injection trigger signals from a manual
injector:
• Auto zero signal to automatically adjust the zero offset of the 2410 refractometer
each time the injector makes an injection
• Chart mark (inject start) signal from a contact closure signal with each injection
Each time the 2410 refractometer receives a signal from a manual injector, it performs the
corresponding auto zero or chart mark function.
