The Analyzer requires you to zero immediately after power on. If Zero Warn is ON, the
Analyzer prompts you for an optional zero after the first five minutes and then after each
subsequent 30-minute interval. To zero at the prompt, follow these steps:
1. Place the Analyzer on a flat surface with sensors/adapters disconnected at the
Analyzer (Figure 3-2.)

2. Press G. Press R at any time to initiate an unprompted zero. Generally, it is
appropriate to zero before any pressure or flow measurement.
3. Reconnect the sensors/adapters (Figure 3-3.)
