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.
