KEYPAD
The Model 3450 keypad (Figure 3–2) allows the operator to access
the gauge software. Troxler designed the keypad for ease of use,
with large keys and an anti-glare coating. Pressing a function key
activates the function only if the gauge is in the
Ready mode. Table
3–1 describes the function of each key.
