5.9 Initial test procedures

5.9.1 Preliminary activities

This section presents a protocol that can be used to ensure that the detector is working in the

proper way.

When the device is set-up, the procedures indicated below should be performed to determine

the speciﬁc characteristics of your unit. We suggest that you save the results in a permanent

location, as they can be very useful when you are performing troubleshooting activities.

Before starting the tests for a new device or after storage, ﬂush the detector with water at a ﬂow

of 1mL/min for at least 15minutes.

The following activities should be performed:

Power up the device. When the detector is shipped from factory, the gain is set to 1 and the

offset to 0mV. The Signal screen should indicate 000 (or a very small signal).

Access the Temperature/Gain screen, set the temperature to 50 °C and press . View the

Status screen and verify that the temperature is rising to the setpoint on the Status screen. Tem-

perature regulation is stable when the Temperature value stops blinking.
