4. Basic Operation

This section covers fundamental operations. For detailed instructions on advanced features, refer to the full user manual available on the Siglent website.

• Vertical Controls: Use the Vertical Scale (V/Div) and Position knobs for each channel to adjust the vertical sensitivity and waveform position.
• Horizontal Controls: Use the Horizontal Scale (s/Div) and Position knobs to adjust the time base and horizontal position of the waveform.
• Trigger System: The Trigger Level knob sets the voltage level at which the oscilloscope captures a waveform. Press the Trigger Menu button to access various trigger modes (Edge, Pulse, Video, Slope, etc.). The Auto button can automatically set the trigger level.
• Auto Setup: Press the Auto Setup button for the oscilloscope to automatically adjust vertical, horizontal, and trigger settings to display a stable waveform.
• Measurements: Press the Measure button to display automatic measurements such as frequency, period, peak-to-peak voltage, and RMS voltage.
• Math Functions: Access mathematical operations (Add, Subtract, Multiply, Divide, FFT) via the Math button. The 1M point FFT function provides detailed frequency domain analysis.
• Storage: Use the Save/Recall menu to save waveforms, setups, or screenshots to internal memory or a USB drive.

3. Setup and Installation

1. Battery Connection: The UPS battery may be disconnected for shipping. Refer to the quick start guide or the full manual for instructions on connecting the internal battery. This typically involves removing a cover and connecting a battery terminal.
2. Placement: Place the UPS on a flat, stable surface, ensuring adequate ventilation around the unit. Avoid placing it near heat sources or in direct sunlight.
3. Power Connection: Plug the UPS power cord directly into a grounded 3-prong wall outlet. Do not use extension cords or surge protectors with the UPS input.
4. Initial Charge: Allow the UPS to charge for at least 24 hours before connecting critical equipment to ensure full battery capacity. The UPS will charge whether it is turned on or off.
5. Connecting Equipment:
   • Connect critical equipment (computer, monitor, router) to the Battery Backup & Surge Protection outlets.
   • Connect non-critical equipment (printer, scanner) to the Surge Protection Only outlets.
6. Dataline Protection: If desired, connect your network cable through the UPS's dataline protection ports to protect against surges on the network line.

4. Operation

• Power On/Off: Press the main power button on the front panel to turn the UPS on or off.
• Display Indicators: The front panel display provides information on battery charge level, load, and estimated runtime. Refer to the full manual for detailed explanations of all indicators and alarms.
• Automatic Voltage Regulation (AVR): The UPS automatically adjusts high and low voltages to safe levels without switching to battery power, protecting connected equipment and preserving battery life.
• Power Outage: During a power outage, the UPS will automatically switch to battery power. An audible alarm will sound, and the display will show the remaining battery runtime.
• Software: Install the power management software on your computer to monitor UPS status, configure settings, and enable automatic shutdown during extended power outages.

5. Maintenance and Battery Replacement

• Battery Life: The typical battery life is 3-5 years, depending on usage and environmental conditions.
• Battery Replacement: The BX1500M features a user-replaceable battery. When the battery needs replacement, the UPS will indicate this via an alarm and/or display message. Follow the instructions in the full user manual for safe battery replacement. Use only genuine APC replacement batteries.
• Cleaning: Keep the UPS clean and free of dust. Use a dry cloth to wipe the exterior. Ensure ventilation openings are not blocked.
