Which is the default startup mode for the instrument?

• A. Normal Mode
• B. Maintenance Mode
• C. Fast Mode
• D. Standby Mode

Answer: (C)

Startup modes determine how quickly the instrument becomes ready to take measurements after power is applied. The default choice is Fast Mode because it drives a quick path to a usable state, running the essential checks and loading standard operating settings while skipping longer, more exhaustive diagnostics and calibrations. This minimizes wait time so you can begin data collection right away. If you need higher certainty upfront, you can still run full calibration or diagnostics later in Normal Mode, but that slows the boot. Standby Mode is for low power and not immediately ready for active measurement, and Maintenance Mode is reserved for service, not routine operation. So Fast Mode gives the fastest, most practical startup for regular use.
