Heater Bar Definition

The Model 332 includes the Heater Bar feature in Display Location 4. The bar gives a visual rather
than numeric representation of the heater output. Each block indicates 2% of heater output with a
large index block every 10%. The height of the smaller blocks reflect the heater range. See Figure 4-3.
