Apply the factors from the table above.
Grab your last 12 utility bills. Find the highest "Demand" value. Compare it to the sum of your connected load. You will likely find you are paying for capacity you rarely use.
Where is the Demand Factor (or Diversity Factor). Standard Demand Factors (Reference Guide) | Load Type | Typical Demand Factor | Notes | | :--- | :--- | :--- | | Lighting (Office) | 0.75 – 0.90 | Fluorescent/LED | | Lighting (Warehouse) | 0.95 – 1.00 | High bay, always on | | General Power Outlets | 0.10 – 0.50 | Varies heavily by occupancy | | HVAC (Cooling) | 1.00 | Worst-case summer day | | HVAC (Heating) | 0.80 – 1.00 | Electric heat is high demand | | Lifts / Elevators | 0.40 – 0.60 | Largest motor only | | Motors (Continuous) | 1.00 | Pumps, compressors | | Motors (Intermittent) | 0.40 – 0.60 | Conveyors, cranes | | Kitchen Equipment | 0.40 – 0.70 | Not all used at once | The "Pro" Calculator Tool (Manual Method) If you don't have a power analyzer, use this systematic approach to estimate your MD.
In most commercial tariffs, the electricity bill is split into two parts: and Demand Charges (kVA/kW) . The Demand Charge is often the larger shock—it is based on the highest average load recorded during a billing window.
[ MD = (Load_1 \times DF_1) + (Load_2 \times DF_2) + ... + (Load_n \times DF_n) ]
Convert to kVA (PF 0.90): ( 21.1 / 0.90 = ) The "Real" Calculator: Power Analyzer / Smart Meter Manual calculations are estimates. For accurate MD (and to verify your diversity assumptions), you need real data.

The classical scanning mode where the variation of a focal plane if any is pre-calculated with a focus map and later the motorized XY stage captures optimally focused images by translating across the region of the scanning.
Uses single 40X or 20X objective combined with a secondary overhead camera for capturing preview (thumbnail) of the full slide including the barcode area. maximum demand calculator
Whole slide imaging is preferred over other modes when exhaustive image capture is needed for deferred access. Apply the factors from the table above

An all powerful scanning mode where multiple images covering all focal planes are captured at every field. The end result is essentially a whole slide scan mixed with pre-captured Z-stack at every position. Compare it to the sum of your connected load
Similar to WSI mode, Volume scanning uses a single 40X or 20X objective combined with a secondary overhead camera for capturing preview (thumbnail) of the full slide including the barcode area.
Volume scanning is preferred over WSI when exhaustive image capture is needed for slides with overlapping cells such as Fine Needle Aspiration Biopsy slides, Pap smear slides etc.
