Which statement is true regarding the 5-day warnings for the device?

• A. Both preventive maintenance expiration and dry gas canister expiration trigger a 5-day warning
• B. Only preventive maintenance expiration triggers a 5-day warning
• C. Only dry gas canister expiration triggers a 5-day warning
• D. Neither triggers a 5-day warning

Answer: (A)

The device is designed to alert you when either of two expiration dates is approaching: preventive maintenance and the dry gas canister. A 5-day warning shows up if the maintenance due date or the gas canister expiry date is within five days of today. This setup keeps the instrument reliable by nudging you to service it or replace the calibration gas before use. So, both types of expiration can trigger the 5-day warning, which is why that statement is true. The other options miss that both dates can prompt the warning.
