Power-On Check
- Connect the power supply within the specified voltage range.
- Turn on the SmartSampler.
- Observe the status LEDs.
- Expected result: Power LED lights solid, activity LED blinks after startup.
Jumper Configuration
- Power off the SmartSampler.
- Open the enclosure or access panel where the communication port jumpers are located.
- Compare the jumper setting with the requirements of your connected sensor (e.g., termination resistor enabled/disabled, bias resistors engaged, RS-232 vs. RS-485 mode).
- Expected result: Jumpers match the intended communication setup.
RTC Battery (CR2032)
Purpose: This maintains date/time when the unit is unpowered.
Locate the CR2032 coin cell battery holder on the main board.
Remove the battery and check voltage with a multimeter.
Expected result: Voltage ≥ 2.8 V.
If < 2.8 V: Replace with a new CR2032 battery.
Reinsert or replace the battery, ensuring correct polarity.
