Why are one or more of my target zones greyed out or missing?
A greyed-out or missing target is caused by insufficient profile information or missing measurements.
The profile information of the appliance is the most important piece of information that mQ collects. Taking measurements is pointless if you do not know what the measurement is supposed to be, just like checking air pressure in a tire is pointless unless you know how much air is supposed to be in it. For example: without a TESP (total external static pressure) rating, we cannot tell if the static is in an acceptable range. Your system might be rated at 0.3" WC or 0.5" WC.
Profile information is how we determine the specific details of the equipment being serviced and how we determine what the measurements should be. Enter the best information you can so mQ can make the best calculations possible.
Go to the Profile page on the Gauge Screen or the Profile page of the project workflow and fill out the heating or cooling profile as accurately as possible.
Another cause of missing targets is missing measurements. The performance of a refrigeration system is directly impacted by the conditions of its operating environment. For example: if you do not measure or enter an Outdoor Air Temp, we cannot predict what the High Side pressure or Approach should be. If you do not measure or enter a Return Air Temp and Humidity, we cannot determine the expected load on the evaporator to determine an expected Low Side pressure target.
Make sure your probes are placed correctly and connected through the Toolbox so all required measurements are captured. For help with workflow checkmarks, see Why can't I get a green checkmark?
